I added about 60 ft to the mainline and 15 feet to the siding on JR Railroad. It was a fun project, and now we will be able to run multiple long trains. Thanks!
Y'know, this is a fantastic line; it's long enough and it fits in with the rest of the yard. For me, a live steam locomotive would be a great part of a railway like this - but that's probably because I rather like live steam locomotives. I'm starting to build my own engine actually.
