I did reply to a seperate thread with something along these lines but thought I would also add it as its own suggestion! As we already had the Trainbow livery on SEHS I wanted to suggest the addition of the Poppy/Remembrance livery on the 395 similar to the rail tour that was carried out to raise money for charity! One article can be found here: (https://www.bexhillobserver.net/news/high-speed-poppy-express-spotted-bexhill-station-2121797) This livery and locomotive could be added in as a rail tour or timetabled service to BML and ECW as although I don't know the exact route taken it went quite far off the beaten track! It may be a nice touch for rememberance or something similar maybe charging a small amount for the livery/layer and donating some of that to the Poppy appeal or some equivalent charity so its a meaningful addition and contribution? Heres an image I found on google of the livery! Simple but effective!
They can't or won't do the poppy and remembrance liveries because the poppy icon is licenced to the Royal British Legion and would cost a lot of money to have for just one skin on a train/loco.
