Downloaded it for interest value today and spent about an hour playing it.
To me, progress feels very slow and nowhere near as satisfying as Transport Tycoon/OpenTTD. The graphics are quite nice, and the game can certainly be classed as "pretty", with the random terrain and town generation working quite well. A feature I don't really like is the terrain and track snapping, which don't always seem to work as intended - trying to create a triangular junction is difficult, and it tries to construct expensive embankments and viaducts where totally unnecessary.
I'll report back further once some patches are in place, and I can't offer it a wholehearted recommendation till some issues are fixed.
