I don't think TSW has had anything like this yet,a single unit dmu with cabs at both ends of the same unit.I'm not sure wether this would be a better route add on or loco add on for a current route but would be at least interesting to have a single unit dmu.Plus it can pull addition units or cars as a option.
Bring it on and it should go to MML EMR paint while Northern Rail version a modern TVL or the Calder Valley Line
Here's 153385 for an example to DTG. 153385 resting in Eastleigh East Yard (18/09/22) by tft#6439 posted Sep 18, 2022 at 2:32 PM 153385 heads out of Salisbury on a loop to Eastleigh and back. by tft#6439 posted Oct 18, 2022 at 7:52 PM
It could layer into WCL, too either on the St Ives branch or on the main line, possibly in pairs or to strengthen a 150/2 formation. In the unlikely event the route were to be extended and the Newquay and Looe branch added, this would be ideal traction subject to correct physics, of course!
