I would love to see the Class 710 on Bakerloo line. In real life, the Bakerloo line has overheads especially for London Overground and Southern services. I would love to see the 710 on Bakerloo line as it would create a sense of realism. I also want DTG to add pantographs on the 377 Southern to have them as a layer on the Bakerloo line in order to create the realism. I think that the main aim for DTG to gain power on the rails especially at platforms 1 and 4 at Queens Park where their is no electricity or power. I think that this would create the realism and also could mean that the Bakerloo line has potential for the likes of Southern and The London Overground.
Bakerloo Line between Queens Park and Harrow runs on the Watford DC lines. The 710s run on DC between Euston and Watford on the same tracks as the Bakerloo Line. The 377s run on the same tracks the 66 AI does on AC. I agree DTG should do a 377/2 and maybe /7 along will all the other 377 and 375 variants they didnt do however its never gonna happen.
