Hi.
First up please sign your posts with at least a first name, (board rules). We need to see pictures of the rest of the sword to be certain but at the moment there are some question marks. The mounts are not shingunto mounts, the hilt wrap is certainly wrong and the tsuba is also doubtful. If you can find it there should be a mekugi, (bamboo peg) under the hjilt wrap at some point. This should push out though you may have to struggle a bit. When this is free the sword should come out of the nakago, can't resist saying that you need to be careful at this point. The decorative motif, which I assume you refer to as the markings, has no connection with anything railway oriented I'm afraid.
A picture of the blade overall and of the nakago with any markings, as well as overall shots of the whole sword will allow people to give you the lowdown.
Don't get your hopes up on this one, it doesn't look too good at the moment. Meanwhile have a look at this site, http://ohmura-study.net/905.html Lots of things to see.
All the best
