I have six of the Hornby lit Pullmans* - there's a fair drag from all the pick-ups - running a supply from the front may be a good idea for that reason also.
*or Pullmen, who knows..?
The sign on the pillar seems a little bit superfluous. You would nearly have to get out to read it.
Still the bridge itself is fairly noticeable - and the upstairs passengers must have reacted pretty sharply...
Bridge strike in London - seven people on the top deck at the time, but only minor injuries, apparently.

Is it definitely railway? I can't quite read the signs, other than "First Class Passengers Only".
Is it possible it's from a ship? The "porthole" makes me wonder that....
Compromise!
Warhammers in your coaches - and tell anybody that notices that they're going to a fancy-dress party and couldn't get anybody to be the designated driver..
I presume that it would be something similar to this - http://www.ocinitrogen.com/Media%20Library/Ammonia%20transport%20-%20Guidance%20for%20transporting%20ammonia%20by%20rail%20(2007)%20-%20Brochure.pdf - some potentially useful pictures in here.
I expected full-size Lego to be available by now - you could adjust your house to suit your needs, even changing it from winter to summer configurations, perhaps.
Whatever happened to the future?
