But it's clear from Tam's blog that support for the south London line reinstatement is very much on her mind - and this aim is being loudly proclaimed by other local parliamentary candidates.

Tam - Just make it plainly obvious would you please? Can you state clearly that you are opposed to the reinstatement of the south London line or any other service (such as the Bellingham to Victoria service) which would remove "paths" from existing services such as our own.

It just isn't possible to get "something for nothing" given the crowded state of London Bridge, Charing X and Victoria - certainly not an entire line's worth of trains. Anyone who doesn't believe this need merely look at the loss of our existing services to CX - these have been "given" to services serving more easterly parts of our own borough. If we are to get them back, somebody else will lose out. There's a limited cake and not enough to go around. To pretend that you can create new lines without a knock-on effect is useful in political terms but won't work in practice.

Can I say that this is not an attack on any political party - just a hope that candidates do not attempt to face in both directions at the same time and expect us to vote for them.
