But, there's no point having London based stock without the 4 rail track to run it on. Mainly because it just looks stupid/unrealistic. Having had a large amount of broken or unneeded set track from Hornby/Bachmann/Lima for a long time without a use, its finally been sorted though and the worst of it being dismantled to provide rail for this:-
A setrack oval featuring both 3rd and 4th rails. For a first attempt, its not gone badly and has been a very interesting practise in adding the conducting rails. Althought I don't think I'll ever build a London based layout, it does provide somewhere to run the London Transport stuff with the correct rails. That said, after seeing how easy it is to get the effect of the conducting rails, never say never..... Just not at the moment.
