No - just alter the gradients so that it's low at Blackfriars and St Pancras, but much higher in the middle.. :-) Paul |

Apparently further work since the LSP was published shows that 1300 was over the top and 1100 will now do the job. Doesn't that make some heroic assumptions that "they" know what the job is? Lynn to Eastbourne requires more stock than Lynn to East Croydon or Gatwick, surely? I believe there is enough evidence in the public domain to strike both Kings Lynn and Eastbourne from the route, namely the recent discovery of Kings Lynn in the IEP programme, and the dissapearance of places like Eastbourne and Littlehampton from the Thameslink final route maps in the more recent South London RUS...

IEPs on the Cambridge fasts then? It's looking likely. The South London RUS saw a major contraction in the route map at the south end to inner-ish suburban, and there's also been a recent disappearance of 2 ECML trains per hour from the final MML/ECML split (was 14/10, now 16/8). The old plan would have made poor use of King's Cross, leaving it half- empty just as its redevelopment was complete. Although I don't know what use the suburban shed will be post 2015.

I suspect that they are thinking of a hybrid arrangement with batteries or super capacitors, as have been proposed for light rail schemes to avoid wiring up historic city squares. the original artists' impressions of Manchester Metrolink, and I think from ageing memory Leeds supertram, showed no wires, which is a far cheaper way of avoiding complaints!
