It would be great if the London Underground Maintenance trains were added this would make a great addition to pulling rail maintenance gear on carriages to Baker Loo line stations on the Underground A London Underground rail grinding maintenance train Image Credit to Alamy I know this would not be added right away due to permission from TFL being a requirement to have the train put into the game The Trains normally grind down the rails to keep them in good shape for the trains to use them daily but when they are not grinding the rails they are normally used to carry rail ballast and rail sleepers from point A to the maintenance site.
