In my honest opinion, I feel like this would be a good route because of its history, and it does create a layout for future lines, such as the district, H&C and Metropolitan line, maybe even just make an extra extension to Upminster and then a small extension to Kensington Olympia or Earls Court for the depot. Cool idea anyways!
fantastic suggestion! Finally more life back in London Paddington has always been a too nice station for one single route and the existing part of the Great Western mainline can provide beautiful AI train traffic (class 166/43 HST). on the way to HAMMERSMITH Beside I'm more of a stock C 'fan because of the engines, the camshaft system and the classic handling, not to mention the appearance of this train of course but an S to start with is also fine C69 / C77
