Staggering Piccadilly Line Trains

Does London Underground appreciate that the vast majority of tube passengers (or “customers”, “clients”, “johns” or whatever might be the latest business-speak term for the long-suffering punters) simply want to be delivered to their destination as quickly as possible (and in reasonable comfort, but let’s put that issue to one side for the moment).

Why, then, would the operators deliberately slow tube trains down?

I’ve been pondering this question on many an occasion over the last year when I’ve had the dubious pleasure of making use of the Piccadilly Line to travel into central London from Acton Town (previously I took the Central Line from Ealing Broadway, which has a different set of problems).

Take last Saturday. I was concerned how long it would take me to get to Golders Green due to the closure of the Northern Line, I understand to test new signalling. As it turned out I needn’t have worried, since a frequent replacement bus service whisked me there from Finchley Road (though anyone who didn’t twig they were best off catching the Jubilee Line there might well have arrived late at their destination). Still, credit where credit’s due.

Anyway, when I left home last Saturday morning I naturally had no foreknowledge of the impending outbreak of efficiency at Finchley Road, so I was keen to get there as soon as possible. When I saw a Piccadilly Line train on platform 4 at Acton Town, I jumped on immediately, even though there were no free seats and I had to stand. When traveling into London, Acton Town is the first station on the Piccadilly Line after two branches come together. Well, they partially come together at Acton Town, since there are two platforms serving Piccadilly Line trains in each direction and two sets of track each way, it seems for much of the distance towards Hammersmith. Sometimes there are trains at both platforms and occasionally there’s even an announcement telling you the other train will leave first.

But on Saturday there was no Piccadilly Line train waiting at platform 3.

Nevertheless, to my considerable annoyance, the full train I was on was OVERTAKEN by TWO other Piccadilly Line trains as it trundled towards Hammersmith. Since the Piccadilly Line operators like to maintain the gap between trains this happenstance added maybe as much as 10 minutes onto my 1/2 hour journey to Green Park to pick up the Jubilee Line.

And the trains that overtook us were fairly empty. That’s right: a full train with hundreds of passengers was held up to allow relatively empty trains, perhaps with only scores of passengers to pass.

What’s going on? The only conceivable explanation is that the Piccadilly Line operators are not concerned directly with the passengers at all. No, they’re simply focused on their timetable. Operational processes, I suspect, take priority over customer service. Now, a glance at the Piccadilly Line reveals there is no branch in the east, only in the west:

It’s not outwith the bounds of possibility that the Piccadilly Line timetable ensures trains join the merged section of track based on where they’ve come from. That is, it could be that trains from Uxbridge are held up to allow Heathrow trains to overtake. I know: this is stupid. The trains appear to be identical. It’s not as if there’ll be a knock-on effect if trains arrive at the other end of the line in the wrong order. In fact, the trains being identical is another problem with the Piccadilly Line: the Heathrow trains need more luggage storage space. More about that issue another time perhaps.

Another possibility is that the trains are being ordered according to their destination. Not all trains go to Cockfosters. Some terminate before then. But holding up trains to ensure that (say) every other train goes to Cockfosters is almost as stupid as ordering the trains based on where they’ve come from. The reason not every train goes to Cockfosters is presumably because they are fairly empty when they get there. So delaying trains full of hundreds of people at Acton for the convenience of a few passengers at the other end of the line would make no sense. Which isn’t to say that’s not why it’s being done.

As I mentioned earlier, Piccadilly line eastbound train ordering is usually achieved by holding trains at Acton Town station. Infuriatingly, you often can’t tell whether the train at platform 3 will leave first or the one at platform 4. Simply providing this information would save hundreds of person-hours of tube travel time every day. But maybe (understandably) the operators don’t want hundreds of people rushing from one train to the other – though not everyone would necessarily move, since there’s the issue of access to those precious seats to consider.

But why hold up any trains at all? Holding up trains ALWAYS delays many passengers whereas managing train ordering – or, as we’ll see, the intervals between them – generally speeds up very few journeys.

Here’s my advice to Transport for London: stop trying to be clever. Start trains according to a timetable, but after that just run them as fast as possible. Hold them at stations only long enough for passengers to get on and off.

The calculation the operators should be carrying out, but I very much doubt they are is whether the amount of time they are costing the passengers on held trains is less than that saved by passengers who would otherwise miss the held train.

Perhaps this becomes clearer if we consider what happens when trains are held to even the intervals between Piccadilly Line trains in Central London. There’s only one tunnel and one set of platforms there, so there’s no issue of trains overtaking each other. Yet frequently – maybe on as many as half of all journeys – you sit in a station and hear that “we’re being held to regulate the service”. But consider the effect of this procedure. ALL the passengers on a train are being held up so that a few passengers further down the line find the train hasn’t already left when they reach the platform.

Such train staggering only makes sense when trains are fairly empty and many passengers are arriving at the platform. But the reverse is the case for morning journeys into central London and evening journeys out. When I’m on staggered Piccadilly Line trains it’s almost always the case that many more passengers are being delayed than are being convenienced.

If TfL is not swayed by the simple numeric argument, perhaps they should consider the business argument that the more often people have a rapid journey, the more they will be inclined to use the Underground rather than alternatives, such as taxis.

My advice to TfL’s London Underground operations team is to stop dicking around trying to timetable Piccadilly Line trains along the whole line. Release them at regular intervals and then get them to their destination as quickly as possible. Simples.

Off the Buses in Ealing

I reported yesterday that TfL is planning to increase fares on average by RPI+2 each year until 2018, and Travelcard prices by RPI+3 over the same period, the supposed justification being that rail fares are to rise by RPI+3. I briefly discussed the implications of this discrepancy, but had a subsequent conversation which led me to consider a different case.

I don’t know about you, but I always feel short-changed if I buy a season pass for a transport network and then find I’d have been better off paying for each journey individually. How likely is this to happen for someone living in Ealing, but working in central London a) now and b) in 2018?

Case 1: A morning and evening peak commuter
This individual uses the tube during the morning and evening peak and sometimes catches a bus back from the station.

In the following table I’ve ignored inflation and just increased costs by 2 or 3% p.a. So in today’s prices a zone 1-3 Travelcard will cost £41.55 in 2018, compared to £34.80 in 2012.

Year   Travelcard cost       Less 10 peak tube fares      Bus fare cost         No. bus fares to break even
2012         34.80                     34.80 – 10*3.10 = 3.80         1.40                             3.80/1.40 = 2.71
2018         41.55                     41.55 – 10*3.49 = 6.64         1.58                             6.64/1.58 = 4.21

So whereas in 2012 our peak commuter would only have to catch the bus 3 times in 2012 to avoid feeling cheated on a weekly Travelcard, he’ll have to catch it 5 times in 2018. If, like me, he walks to and from the station most of the time, he’ll be in a bit of a dilemma by 2018 as to whether or not to buy a weekly Travelcard.

Case 2: A morning peak and evening peak/off-peak commuter
It gets even worse in the case I actually discussed yesterday. The evening peak is from 16:00 to 19:00, so many people working in London may not actually travel home until off-peak fares apply. If this happens 3 times in a week, then the calculation changes somewhat:

Year  Travelcard cost     Less 7 peak, 3 off-peak tube fares     Bus fare cost   No. bus fares to break even
2012        34.80               34.80 – (7*3.10 + 3*2.60) = 5.30              1.40                     5.30/1.40 = 3.79
2018        41.55               41.55 – (7*3.49 + 3*2.93) = 8.33              1.58                     8.33/1.58 = 5.28

By 2018 this commuter will need to use the Travelcard on more than one bus each work-day (or for leisure journeys) to justify the expenditure.

Personally I feel the Travelcard should be a better deal. In London, it seems, regular tube users are likely to pay as much per journey as occasional travellers. And it seems unfair for commuters to have a dilemma as to whether to by a season ticket or not – I haven’t even discussed the effect of Bank Holidays, leave, sick-days and occasional home-working. This is the opposite of the case for main-line rail commuters who get a tremendous deal compared to the occasional traveller.

From TfL’s point of view inflating the cost of Travelcards relative to pay as you go (PAYG) fares may also not make sense in the long-run. The result may be that more of us in suburban London stop buying Travelcards and instead cut out as many bus and tube journeys as possible. As I said yesterday, “maybe it hasn’t occurred to TfL that people might consume less of their product when they put the prices up”.

Off the Buses

Boris has announced the 2012 London Transport fare increases already. Do we always get an announcement at this time of year? Or is our leader trying to get the bad news out of the way as long as possible before the mayoral election in May 2012? I note that the last time I visited this topic was in January this year when the last fare rises actually came into effect. With a bit of luck there’ll be a double whammy with negative stories now and in January 2012.

Let’s get the ball rolling with a negative story, then.

The BBC provides a link to the documents issued by the mayor. I only looked at the first one (pdf), which seems to tell me everything I need to know.

It turns out that TfL has a Business Plan based on fare rises of RPI+2%. News to me, most likely totally unjustifiable, but certainly worthy of discussion.

First, are we to believe that TfL’s costs rise faster than general inflation? This seems unlikely, though we do know that many of their employees are extraordinarily privileged to the extent that they apparently deserve a bonus just for doing their job during the Olympics. A lot of people will be working then, and the vast majority will be paid their normal salary, and would expect nothing more. I don’t support the present government, but I was rather hoping they might look at strike law with a view to stopping Londoners being continually held to ransom.

Second, on the customer side, how is it possible to bear continual above inflation rises in transport costs? I’m thinking of low-paid workers travelling into central London. The cost of a weekly Travelcard (tube and bus) season in 2012 will be £34.80 to zone 3, £42.60 to zone 4, after rises of 8.1% in each case. That’s about £1 per hour of work! Surely the minimum wage for central London needs to be higher than elsewhere to compensate? Assuming your pay rises roughly in line with inflation (which is doing well these days), then, if you have to spend more on transport, you have to spend less on something else. That is unsustainable. TfL is not like national rail, which, as the Transport Secretary pointed out this week, is now a service for the wealthy. It is simply not realistic for TfL to increase its prices by more than RPI for a long period of time, unless the lowest wages are increasing by at least the same rate.

So why has TfL adopted the RPI+2% formula? Maybe the document I downloaded doesn’t tell me everything I need to know after all. There seem to be a lot of TfL Business Plans, but the 2009 one for 2009/10 to 2017/18 tells us what we need to know:

“…fares in January 2011 and in subsequent years are now assumed to rise at RPI plus two per cent.”

So it is indefinite. And the purpose is clearly to increase the proportion of operating costs covered by fares and therefore reduce what TfL term “Net operating expenditure”:

Excerpt from TfL Business Plan 2009/10 - 2017/18

Let’s just note in passing that the congestion charge is going to raise less in 2017/18 than 2009/10!

Bizarrely, TfL don’t state what the figures in the table refer to. Presumably they’re 2009 £s (i.e. adjusted for inflation). Assuming that is the case, TfL assumes a steady growth (several % p.a. varying erratically) in passenger numbers as well as a 2% annual increase in the fares. They say:

“As the economy recovers from recession, it is projected that demand will return to current levels by 2012 and then continue to grow strongly as London’s employment and population increase, with demand reaching record levels by the end of the Plan.”

This is a fairly heroic assumption, as it seems to assume a very low elasticity of demand – maybe it hasn’t occurred to TfL that people might consume less of their product when they put the prices up. I’ll return to this point in due course.

TfL’s Business Plan suggests they expect costs to also rise by several % p.a. more than inflation, and also erratically, with a bigger increase in 2012/13 presumably to reflect the need to bribe the staff not to disrupt the Olympics, and in 2017/18, perhaps because Crossrail comes onstream (though there is no concomitant increase in fare revenue).

So in answer to my earlier questions, it seems that unlike every other field of economic activity, running London Transport becomes less and less efficient with time. And low-paid London commuters are expected to pay an ever-increasing proportion of their income on transport.

It seems to make sense that the fare-payer should cover the cost of the service, but let’s make a few observations:

1. Unlike many others, the London transport market is not segmented, so that those who can pay more do (compare walk-on national rail or air fares with advance tickets). I’m not saying I’m a fan of dramatic market segmentation. It creates its own problems, such as making urgent travel punitively expensive for everyone. But in an unequal society, it does allow some access to services for the less well off. Obviously it’d be better to have greater income equality in London, but until that happy day, subsidising fares helps alleviate the problem.

2. The fare-payer is not the only beneficiary of the London transport network. Just as, in the ’80s and ’90s, out of town superstores and malls benefited from the motorway network, such as London’s M25, (and generally improved roads), so the new millennium has seen similar developments – notably London’s twin east and west Westfields (or perhaps the new one should be an Eastfield?) – piggybacking on the city’s public transport network. Maybe these businesses should chip in and subsidise fares from the taxes they and their customers pay.

3. Just as for customers, businesses benefit from the availability of employees. They don’t pay a higher minimum wage even for staff having to travel into the centre of London. Maybe they should, but in the meantime it doesn’t seem entirely unfair for businesses and higher paid employees to subsidise the fares of the low-paid through the tax system. £1 travel cost for each hour of work is a lot for those earning little more than the minimum wage of £6/hour.

4. Today’s fares shouldn’t subsidise investment. That should be paid for by future fares, i.e. the beneficiaries of the investment. And in fact, the goal in TfL’s Business Plan is not apparently to increase fares to pay for more investment. So when Boris mentions investment in the same bluster as higher fares he’s actually being misleading and trying to deflect criticism.

And on top of this, there’s an anomaly in the pricing scheme – this is what really got my goat and prompted me to delve into the mire of transport fares once again:

“Travelcard season prices increase by 8% overall because of the link with National Rail fares which, as approved by the Secretary of State for Transport, are to rise by 8% (RPI+3%).”

What tosh.

Fares other than Travelcards are going to increase by RPI+2% (7% this year), but Travelcards are going to increase by RPI+3%, because you might get the train.

Do they think we’re stupid?

The price for a mainline train within London is the same as the price for the same journey by tube. I can go to Ealing Broadway and get a train to Paddington or I could get the tube there. I’d touch in and touch out with my Oyster card the same either way.

The daily limit applies just the same whether I use tubes and buses or tubes, trains and buses.

No, increasing the weekly limit faster than other fares (and remember this won’t happen just this year, but indefinitely until the policy changes) affects certain people disproportionately. The sort of people most affected are those who use the system most, that is, those dependent on it most likely to get to work, that is, those with least choice.

I’m in zone 3. If you need to get a bus and tube to and from work – and tube stations are thin on the ground out here, so often a long walk – then you’re going to need a weekly Travelcard (£32.20 in 2011; £34.80 in 2012), given that 10 peak pay as you go (PAYG) zone 1-3 tube journeys alone cost £29 in 2011 and £31 in 2012.

Of course, the tragic thing about all this is that many Londoners get the bus all the way into the centre to save a few pounds at the expense of perhaps an hour a day. But even they’re being screwed. The cost of a 7 day bus and tram pass is rising by 7.3% from £17.80 in 2011 to £19.10 in 2012. I can understand why the individual bus fare is increasing by 7.7% – that’s to keep a round number (£1.40 in 2012 after £1.30 in 2011). But £19.00 for the weekly pass would have been a 6.7% increase. Why not stop there? Gratuitous.

As far as I can see, the main beneficiaries of the fare changes for 2012 are off-peak occasional tube travellers for whom the zone 1-2 fare rises by only 5.3% (£1.90 to £2 – OK a nice round figure) and the zone 1-4 fares by a mere 4% (£2.50 to £2.60). For the last, £2.70 would only have represented an 8% increase. It seems fairer somehow to impact what is most likely discretionary travel a little more and that for people trying to make ends meet a little less.

What else could be done to help the low-paid? Besides fair pay, that is.

Well, here’s another curious anomaly. “Peak” in regard to the daily limit means 4:30-9:30am. That is, if you travel between those hours the daily cap will be the peak rate (£10.80 in 2012, rather than the off-peak £7.80). But if you don’t reach the daily limit and just pay as you go, the peak is 6:30-9:30am and 4-7pm (16:00-19:00). Odd. Why not give people more of an incentive to travel before 6:30am, when presumably there is spare capacity? Why not make the peak daily limit apply only if you travel between 6:30 and 9:30am? Wouldn’t this be sensible demand-management? It would help at least some of those who currently spend more than the off-peak daily limit because they take a bus and tube to work (e.g. in zone 3 in 2012 a pre 6:30am tube fare, a peak return fare and two bus fares would come to £2.60 + £3.10 + 2x£1.40 = £8.50, above the off-peak cap of £7.80 but below the £10.80 peak cap).

The case I’m most interested in is my own, of course. It’s the borderline case, where I may as well walk to and from the tube station rather than catch the 297 (or infrequent E10). If the service were more frequent I might take the 297 to Ealing Broadway. As it is, I never do, because I don’t know how long I’ll have to wait, at least until I get to the stop, when there may be a few clues. When I come out of the station, though, I can sometimes see the bus waiting, or at least a queue of people. I’d take it more often if they actually bothered to display a departure time. But sometimes it comes down to a cost consideration. Basically, I’ll rarely pay the full fare. I might take the bus, though, if I reckon I’ll hit the daily limit.

I note that for 2012 the daily limits for zones 1-3 are increasing by more than the relevant tube fares. The peak daily limit is going up from £10.00 to £10.80 (8%) whereas the peak tube fare is increasing only from £2.90 to £3.10 (6.9%). And off-peak, the daily limit is going up from £7.30 to £7.80 (6.8%) whereas the tube fare is increasing only from £2.50 to £2.60 (4%).

So, in 2011, an off-peak return tube journey to the centre, and a journey within zone 1 (£1.90) came to £6.90, leaving 40p of the daily limit to be taken up by a bus fare, but the same itinerary in 2012 would come to £7.20 before the bus, which effectively costs me 60p. OK, it’s a 50% price increase but I expect I’ll still hop on a 297 at Ealing Broadway station if passengers are boarding!

Nevertheless, if TfL persists in increasing weekly Travelcard prices by more than other fares, there will be people who switch to pay as you go, and walk to tube stations rather than take the bus. Maybe this is all very healthy, but it seems a strange policy. It would make more sense to me to raise all TfL prices by exactly the same percentage and charge – now that it’s all electronic with Oyster – to the nearest penny if necessary.
