Скачать или смотреть Source SDK - Moveable Trains (func_tanktrain)

A fairly basic tutorial showing you how to make an automated train (tracktrain for the sort you could control in Half Life 1, perhaps I'll cover it at a later date).

0:04 - Making the train itself
0:13 - Making the path for it to follow

PROBLEMS
0:52 - Train goes through ground!
1:07 - Train gets blocked by player
1:14 - Unwanted shadows on train
1:29 - Problem nobody will actually get but will insist they do
