Most of the train track is allready set up with the TX. (expandmd06.mix)
there is some track (90' crassings. "Y" switches and end stops) that need rulesmd.ini editing. but most of the rest works.
NOTE: FA2 shows the old mono track in most of the terrain. But fixis up in game.
track.ini is supposed to be merged into any map file (use the FA2 .ini editor to merge it in) that uses tracks, it doesn't get used on its own. You only need to merge it into a map file if it is supposed to be mod independant (i.e. doesn't rely on the mod having the code in the rules.ini file).
