Have you folks seen this? It adds a 52, 101 and 08 to the GWE route with new timetables for them.
It’s an interesting idea to give a BR Blue take on services out of Paddington... except the route remains set in 2016 (itself a past era) with all the modern infrastructure around.
Release a 2022 DLC (with IETs, 345s and 387s), that would fit better and probably get more interest from their target market, IMHO.
It has been pointed out on the DTG forums that these trains already exist in TSW, and that to use all the features of this DLC in full, you need the Class 31 and BR Heavy Freight (which in turn need Northern Transpennine and Tees Valley)... making this DLC for DLC for DLC.
