Simce dovetail have trouble licensing newer trains I thought I would do a route set in the 90’s.The route could be from Ealing Broadway to Tower Hill. The District line was the second line of the London Underground. The D78 stock was in service by 1978. You can’t see the d stock today but you can see it as a br class 230. The district line was fully replaced by the S stock trains in 2017. (Tower Hill is one of the terminus’ for the District line).The O stock is a train which was to be replaced by the D78 stock. So they could set this in the 90’s.The speed would be about 55mph since they did not reduce the speed yet.Earl’s Court is also a terminus for the District line Here are some pics.
