I don't know if this should be in suggestions but the class 50 is one of the greatest BR era locos and has a long history of running service trains and railtours all over the country, it would be really good to see it in the game.
Was it built after 2010? Is it powered by electricity without an onboard diesel generator plant? Does it have a narrow window that is smaller than an archery slit in a medieval castle? Does it have sounds that can be synthesised from a milk float? Does it have a simple one handle push to go, pull to stop? H'mm I don't think it stands a cat in hells chance of even making it to the whiteboard in the TSW ideas chamber, let alone being made. Seriously, along with the Deltic and Class 56, frankly criminal we haven't already seen a Class 50 along with a suitable route in TSW.
Realistically probably not, though I do think JT have left a key laying about for more BR era diesels. I would love to see the key used, though thinking realistically again, I am trying not to laugh at myself.
Far to exciting for the TSW community. A desiro or Flirt is far more interesting and fun than a late 60s type 4 that thunders along the line with 13 coaches behind and and four exhausts pumping out the audio entertainment. What we really want is more PIS more GSMR more moths, more pianos more lifts and trains that sound like something a YouTube channel would advise gets rid of household pests.....
