I think it would be cool the have a London Overground class 378 'Capitalstar' for the Bakerloo line to run services on the section of track between Harrow and Wealdstone and Queens Park were the overground shares track with the bakerloo line.
I would like for this loco to come , but I find it unlikely it will due to the small amount of stations it would use on the route .
I'd love to see this train, but I'd much rather see it come with a new LO route and the train layered onto the bakerloo line. Are all platforms at Queen's Park useable?
