The problem with the Hayes Line is that although it is the obvious one to grab, it doesn't have much traffic potential. Low density housing and badly sited stations. I did some back-of-the envelope calculations once, at best, Lower Sydenham to Hayes would generate around 20,000 journeys a day (for comparison, the last three stops on any Underground Line in North London generates more).

South London has always been treated as being second class by London Transport. The Victoria Line was always going to go all the way to Walthamstow (Zone 3) in tunnel, but Brixton (Zone 2) was always a struggle. I looked in the London Transport archives at projected passenger usage south of Brixton, the figures were absurdly low, with a station slap-bang in the middle of Streatham estimated to generate 1/3 the number of passengers as Brixton IIRC.
In September 2010, Jonathan Roberts Consulting produced a preliminary appraisal of options for extending the Bakerloo for LB Lewisham: http://tinyurl.com/c7fhltm - well worth a read.
Thanks for drawing our attention to the PTAL number. Why is this not more widely known? I'd have thought estate agents would be screaming PTAL 6 from the rooftops.
I'd love to see the Bakerloo take over the Hayes line with a spur to Beckenham Junction. While you're correct about low density housing plenty of old Victorian homes have been replaced with apartment blocks. The biggest issue for the Hayes line is it's seen as a driver of commuters in the peak hours between the suburbs and the City/town. You either take a semi-fast to Charing Cross or wait 15 minutes for a slow train via Lewisham to Canon Street. Weekends are a joke. Put the Bakerloo line and with tube frequencies alone you instantly make the line more attractive. Beckenham Junction appears for more popular than New Beckenham (location helps) so I see no issues with lodgings there. We only get half hourly services from Victoria to Beckenham Jn on the Orpington line after 8pm so a direct link to the West End without a torturous wait at Victoria would be a godsend. Unfortunately this is a conservative area that resists change. No one will want a depot built and despite the obvious benefits of a more frequent service into the West End and cheaper pay as you go fares there will be resistance from commuters who like their direct route into London Bridge and Canon Street. The no campaigners will say tubes have fewer seats ignoring the fact you could catch one every couple of minutes as opposed to every 15-30 minutes.
@Dan I'd imagine it sounds a little geeky, not sure. All planning departments in London use it religiously...possibly a bit too religiously.
I have always thought the Bakerloo line taking over the Hayes branch is about the daftest idea ever to be suggested in the area of public transport in London. It makes the cable-car look relatively sensible. It started off as a suggestion from Lewisham council as a way of getting the Underground to Lewisham but this is a council that can't even be bothered to include an obvious DLR extension to their masterplan.

I could write masses on why not but basically:

- Commuters on the Hayes line tend to work in the city near Cannon Street. What is the point of a plan that takes away the direct route for a lot of people ?

- From the first point it is not simply just a case of having spare capacity on the Bakerloo line. How are they going to get to the city? On the Northern line using the spare capacity on that ?

- People simply don't grasp the difference in capacity between a standard above-ground train and a little tube train. It is about 3 to 1. Using tube trains on the Hayes line would literally create problems down the line and that spare capacity would be completely inadequate for the demands put upon it.

- There is no point in considering the scheme as if it were to be implemented today. Such a scheme would probably take at least ten years to come to fruition. We would then have 12-car trains on the Hayes line and little high-density "Evo-stock" trains on the Bakerloo. If the latter it would be a very uncomfortable for a long commutes from places like West Wickham and Hayes. Also, at today's rate of increased public transport use the spare capacity on the Bakerloo would probably no longer exist.

Whatever Max thinks about not having much traffic potential the reality is that this is the only line for a very large catchment area that serves Cannon Street station and the trains are currently very crowded indeed in the rush hour. Nowadays it also has a healthy off-peak level of traffic.
I don't see why the existing Southeastern pattern could not continue, with Haykerloo trains slotting in between - like the Watford DC line. Would trains run all the way from H&W to Hayes, or Hayes to QP, BKJ to SbP and H&W to E&C?

By tube frequencies, probably every 10 mins would do anyway, which means they could slot in between the 6tph during the peak. Also, this would solve the problem in which I often find myself at Ladywell with a Z2+ travelcard, and a 30 minute wait.
I like the idea of a Bakerloo line extension down the Old Kent Road. If not a full scale extension but how about in stages. With a two station extension to Burgess Park and then a couple more to New Cross Gate.

The problem is TFL have other priorities. The Costs for this are high but the benefits lower compared to other schemes. With London's growing population other schemes will always win out.

TFL is foccussed on two things only. Getting the money to upgrade the rest of the deep tube network (plus possible separation of the Northern line) and the building of crossrail 2.

Future tubes under London are pretty much going to be mainline gauge from now on as they carry so many more people. TFL wants £12 billion plus for Crossrail 2 with construction to start in the 2020's just after they finish the tube upgrade programme. Of course when that is done they will just want to start on crossrail 3.

So no real prospect of £3 or £4 billion projects I'm afraid. Only those that cost £1 billion or less. Preferably less, so maybe some Tramlink schemes and Overground improvements.
Looking at the area on Google Maps, switch on the Wikipedia layer, and two disused stations will appear on the existing railway between E&C and Loughborough Junction: Walworth Road and Camberwell.

Wouldn't it be the cheapest option just to reopen them?
Wasn't there some talk of a station at Old Kent Road then connecting up with the Greenwich line to Slade Green?
The PTAL numbers may be geeky but they are also fascinating. What DG's map doesn't show is that once you head south of Peckham Rye and Nunhead you enter another railway wasteland. While I don't agree with Pedantic's passionate dislike of the Haykerloo proposals I do agree that the reduction of capacity he outlines do make the scheme unworkable.

Greg - I agree and do wonder why there have been not been more campaigns to re-open those 2 stations.

Rational Plan - It's not just schemes over a billion pounds that are hard to find money for but any scheme at all not funded by developer money - just look at the delay in getting Tramlink to Crystal Palace or the GOBLIN electrified. But I agree with your main point that, rightly or wrongly, it is only huge schemes that are seen to be worth funding.
Pedantic:

Evidence please. If you disagree with my calculation, maybe you could supply one for yourself. I base my numbers on passenger figures supplied by Network Rail and TfL. Rather than your own personal opinions (Max is wrong, I am right) lets see some proper numerical arguments for a change.
I'm not sure why crowding as a result of the northern extensions to the bakerloo precluded the southern one being made - on the contrary a better laid out southern terminus, would seem to help, and the extra peak traffic would be in the other direction, rather than unbalanced as it is at the moment.

Re-opening the Camberwell and Walworth stations on the Thameslink route would be a no-brainer, if FCC took any interest in that route.

I think you'll find Peckhham's route to the West End at Victoria is quite direct, with only one intermediate stop. However, it's less frequent than it was, as the stopping service via Clapham High Street and Battersea Park has been hijacked to go to Clapham Junction.

Peckham's route to the City is not as good.
@Whiff, yes there have been delays to Goblin and Tramlink. Goblin because there is a turf war between the DFT and TFL and Tramlink is delayed due to budgetary pressures.

But, even though TFL just wants Crossrail 2, it needs to offer some baubles in the mean time. We are talking about 2030 before it opens.

I imagine a few hundred million projects will be programmed in.
Excellent stuff. I'll need longer days if there are going to be too many more posts like this. Yes, thanks for drawing attention to the PTAL numbers. The (very) large scale maps were fascinating. I've never seen anything quite this detailed available free online. Fixmystreet used to get up to 1:10,000 IIRC but withdrew these, I haven't checked back recently.

Could I register another vote for 'Not Hayes'. I quite liked the suggestion on londonreconnections about taking over the Dartford via Bexleyheath Branch and extending to Bluewater, but appreciate this would also mean replacing big trains with little ones. Guessing you are correct and it's all academic really as nothing is likely to happen.

I've ordered a copy of The Blind Men and the Elephant mentioned on londonreconnections to read to my pesky children. Sounds fascinating. Why did I not know about this before?

Keep up the good work, it is much appreciated. Time for me to do some work now, better late than never.
I remember seeing a sign on the Bakerloo a few years (10?) back saying "trains to Elephant & Castle and Camberwell". Did I imagine that? I think it was at Paddington or Warwick Avenue.
Certainly Max,

A Bakerloo line train has 268 seats. Any "Evo" train will undoubtably have fewer.According to this site a 12-car class 465 has 1032 seats and it gives a total passenger carrying capacity of 1410 which I reckon is very conservative.

The Hayes line currently has 6 tph and from personal experience and other comments on the web it is very full in peak hours - which makes you wonder how busy it would be if there sufficient capacity.

I think it is reasonable to assume that the Bakerloo will have a maximum of 24tph because it will presumably still go north if of Queens Park and have to interface to a non-automatic railway.

Based on the presumption that each 12-car train will be packed to capacity then each Bakerloo line train will have to accommodate at least an extra 350 passengers per train. Of course if the extension has other new underground stations between Ladywell and London Bridge the figure will probably substantially increase. There will still need to be space available at Waterloo to cater for increased traffic expected to transfer from SWT between now and when it would open.

I cannot get any figures for where people travel to from the Hayes line but personal experience suggests that this is predominately the city in the peak hours with people either taking a Cannon Street train or alighting at London Bridge and walking. I would love these figures to be available because it I think it would clinch the argument - or alternatively show me up to be wrong.

Don't forget a large portion of at least an extra 350 people per Bakerloo train (i.e. every 2½ minutes) will want to travel to Charing Cross, London Bridge, or Cannon Street. In the case of the latter two there needs to be capacity on other lines for them to do this.

So basically I just do not believe that in ten or so years time it will be humanly (or at least humanely) possible to accommodate an extra 350 passengers per Bakerloo train on top of what the demand will then be.
I understood that the real issue was that there is no clay in SE London to tunnel through and so it was going to be much more expensive on a per mile basis to actually construct a line.
I forgot to add that the same Jonathan Roberts that THC mentions (presumably no relation to Max) did a presentation to the London Underground Railway Society entitled "Beyond the Elephant". It is reported here.

Loads of numerical arguments for those whose like evidence and not just opinions.
Why can't we have option C, but terminating at Lewisham? After all, the Jubilee and DLR happily terminate at Statford without taking over one of the mainlines.
Cost isn't the only reason Boris Johnson scrapped the Cross River Tram. It would also have got in the way of other traffic. Cars or trams? Boris chose cars.

With the lack of access to rail, the transport system doesn't cope. Around 100,000 people live in that "transport hole" in Southwark. The area is heavily dependent on buses (no Barclays bikes here). In some parts, it is just one bus route. Try squeezing or elbowing your way onto a 343 bus in the Burgess Park area during the morning rush hour. It's not recommended for the faint-hearted.
I wouldn't put too much faith in that automatic PTAL calculator. I entered my postcode and it told me I was level 3 - just one step above Camberwell. On closer inspection, opening up the detailed report revealed that it had completely failed to spot the existence of Wimbledon station!
Cross River Tram would have affected all road traffic, not least the buses on the routes crossing it including the already badly-congested routes along the Strand and Fleet Street. Since the detailed plans included closing, rather than using, the Aldwych underpass, there would in fact have been even more north south traffic coming off the bridge at street level, even without the trams.

As I have long advocated, restoring Waterloo - City buses (currently 4, 26, 76, 172) to the route the 76, 149, and 168A used to take until c1980 via Blackfriars or Southwark bridges instead of the big dogleg via Waterloo Bridge would be a very simple improvement. TfL have not explained why this can't be done, other than "we know best"
There would not necessarily have been more traffic coming off Waterloo Bridge onto the Strand/Aldwych junction. Waterloo Bridge would have been closed to general traffic. The bridge would have remained open to trams, buses, taxis and cycles.
I think any extension of the Bakerloo line needs to head South to Camberwell Green, so it links up with all the main Bus routes.

After that, whether it continues South to Denmark Hill then Herne Hill or East Dulwich, or heading off East to Peckham and New Cross it would serve Southwark well all hours.

Simply heading through Burgess Park towards New Cross, it would just be peak time commuter route.
How about Lewisham Shopping Centre instead of Westfields?

Only problem is Lewisham shopping centre will be a stop on the DLR extension and NOT the Bakerloo extension to Catford.

Lewisham like Westfields just different.
