Could we try and have the class 141 and 143 pacer units come to TSW5 i know they would likely require a route in their respective time frames aswell
Would be unlikely to get a licence for a pacer because GWR would prefer focus or more current stock for their brand image you could maybe use something backdated.
The 141 would fit superbly onto NTP for services between Leeds and Huddersfield. NTP is set around the time they were first into service. I have suggested this multiple times as a dlc for NTP but still not arrived.
