I know that the route is steam but there are 2 diesels and 27 miles overall I have been on the route pleanty of times
If in doubt, post a link to wikipedia https://en.wikipedia.org/wiki/Romney,_Hythe_and_Dymchurch_Railway This little narrow gauge railway runs in the very south of Kent between the seaside towns of New Romney, Hythe and Dymchurch, and also onto Dungeness Used as a school train as much as a tourist draw the little trains also perform regular runs along the full length of the line. They also have an excellent website themselves https://www.rhdr.org.uk/
Actually, I'd quite like this. Although probably when they've added steam trains, because just the diesels would be boring.
