Now I'm not a transport geek, but I am genuinly facinated by London's tube network - it's the oldest underground railway in the world and has many old gems left in the older stations.
There are websites dotted around the web dedicated to disused stations and old underground maps (all very facinating if you ask me), but I thought I'd start a thread on here for those of us who juse have an "amateur" interest!
I'll start off - recently on the Disctrict line I've seen a refurbished train on the line, all very nice and a lot more modern on the inside than the original design.

Does anyone know if this is more than a prototype - are these going to be rolled across the fleet?
