Here I describe some steps to create your own town-names:
Open windows explorer (windows key + E)
browse to “{install directory}\Train Fever\res\config\name\{Language which your game is in}” (for default steam installation install directory is : “C:\Program Files (x86)\Steam\SteamApps\common”)
Make a copy of “towns. lua” as backup
Open the original “towns.lua” with notepad or another source editor
The first 2 and the last 2 lines in this file should be untouched. All other lines could be removed, adjusted or even new lines could be added. Make sure each of those lines keep the following format. every line looks as follow (as in the original file): {tab} “{town_name}”,
