And is there a reason, other than platforms, that we can't have 15 or 16-car units in the south east?
I think spacing between signals is one reason why 15 or 16 car trains cannot operate in the south east.
Its the cost of the extra works. To change from 12 to 16 car trains on the Brighton MainLine was costed at £1bn+ and the extra cost of rolling stock. New trains aren't cheap. Whats forgetten about the Thameslink Project is that out of the £5.5bn its costing, £3.5bn is for stations, track and signalling. £2bn is what its going to cost to get all the new trains and depots up and running.
Simply put its not good valve for money. Signalling was mentioned but you also have to do platform extensions, change track layouts in stations. But the biggest concern isn't actually anything to do with the running line. Basically of you start running 16 car trains in peak your concourse can't cope so somewhere like Victoria would need expansion and that isn't going to be cheap.
This is why there is work on Crossrail/Thameslink style routes as they going through London they should in theory allow for more balanced traffic flows.
:roll: This is what annoys me...
People in the south east don't have a clue what its like up north, we have the same problems, but the moneys always invested there. You're looking for 12-16 car trains, and we're still looking for 3 car or 4 car trains!
How on earth is it? London/South east gets a lot more investment than the north, and im not saying we need 12 car trains - we need stock with either more seating or lengthened 142s! We don't have any of that because its all being put into the south east, im sorry - but they moan about 12 car trains, and we get a mere 2 car full and standing, pulling away with another hour to wait...
Right I say this as someone who lived in the Northwest (Manchester, Liverpool and Warrington) for 18 years and have been in London for the last 3 years.
London simply has more people travelling. Yes the north has massively overcrowded trains but London does as not just people within the London area travel but people from all over the Southeast creating extra pressure.
Basically once Crossrail and Thameslink is finished the north needs to get extra units and plough some funds into getting either more trains or lengthing the ones they have. Putting up OHL seems to be one way to achieve this as you can have new eletric trains on the major routes and used the spare units to double up other services.
The north problem are easlier to solve but don't think that because you have a 2 car train that you have worse situation than people with 8 and 12 car trains. You don't. London and the Southeast needs longer trains but still gets worse overcrowding than the North.
But if the Northern council's and PTE's could work together to propose something then they should get the funding. But its not going to be easy.
Look at what Manchester has done with the trams and raising its income to achieve massive investment in its Metrolink system. Its even paying for the Airport extension without money from the Central Government because it wants the extension so badly. Hell the Canary Wharf group is building the Canary Wharf Crossrail station to a tune of £500m. (And if Woolwich station gets built on Crossrail then its will be privately funded as well).
And before anyone says anything, Id actually like to see some major investment in the North's railways and I mean major. Its easy to solve the problems. But everyone is going to have to put into the fund. If business actually put more money then there could be more investment.
