Luis:
is this for your American railway? If so, get an atlas and read all the wonderful names that we pinched from every nationality we came in contact with. In southern Ontario you can find, within 50 miles, London, Paris, Zurich and Lisbon. (Used to have Berlin but that diappeared during one of the wars.) Your railroad doesn't have to reach any of those places (yet); it can have great ambitions!
If you're married, put your wife's name in somewhere. If you're not, be very careful - relettering everything to remove an old girlfriend is only slightly less painful than removing a tattoo.
Avoid bad puns! They start to grate after a number of years.
