Well, i had to think about posting this link here.
Here's why.
MaSzyna(Machine or "He has the rail")  is a train simulator from Poland. Luckily some of the things are translated to English.

Please be advised. This program is still beta phase and will remain that way for a long time

Obeying signals and rules is not enforced
There is no collision detection (although you can fall of the track if you go fast enough :p)

OK, now for the links. Like i said earlier, sim is in polish but the forum has an English section.
Link to the forum (english subsection) http://eu07.pl/forum/index.php/board,13.0.html
Link to the download http://eu07.pl/forum/index.php/topic,5472.0.html
Link to the download list (in polish) http://eu07.pl/download/

YOU CAN TRANSLATE THIS AND OTHER SITES WITH GOOGLE TRANSLATE.
