Only a minor nitpick but playing on PS5 after playing a few services, I noticed all the coach numbering is the same, M12345 on multiple services using different locos. A bit of feedback there for Rivet and Dovetail.
Actually not sure this is a Rivet issue as I have had the same issue one NTP, WSR and GWE when playing Diesel Legends of the Great Western.
Ah, I've never noticed that before and I have all of those DLC, well it's not a major issue but at least it's been spotted and it's feedback that they want. Enjoying the route so far.
Interestingly I'm currently running the 08.30 light loco move in a class 40 and as I'm pulling alongside the 08 with my coaches the 6 Second class are all numbered as the image you've posted and the 3 First class (gold band at top) are individually numbered
They messed it up on Diesel Legends 12345 is Nothing, close would be a Mk3 TSO 12004-12168 but that number is outside that list. Once they used the stock on Diesel Legends all DLC that uses layered NTP stock has this mistake. However NTP is okay but use this anywhere else it's the wrong numbering. Yes it maybe a nit pick but it's a glaring mistake that annoys the hell out of me with a wrong coach number. I suspect that they saw the FK coach with a 13XXX number and changed it in error? Mk 2 a's of this spec were numbered between 5257–5433 with 177 built. I have attached is a Mk2a 5378 in NSE livery of that type seen on an Exeter to Waterloo train 29/03/1993 at Gillingham Dorset.
Just noticed this bug show up on West Cornwall with the class 47/4 (PS5). All the regular class coaches showed the unit number M12345. Saw it on 2 separate 47/4s running on the line. Oddly enough both trains had 1st class coaches for the last 3 and those had proper numbering.
