I tried to use that, Stugger's plugin is based on that and seems to work fine in the video he uploaded

Tried creating a path and a train with that plugin and the behaviour is strange, it creates the track, the cans appear, but when i start the train it just makes cans disappear, no model is shown there.
(Yeah, i have set a model before that)
Console:
Setting CBaseEntity to non-brush model models/props/cs_office/vending_machine.mdl
PrecacheScriptSound 'none' failed, no such sound script entry
Dynamic prop [U:1:108073217]_trainprop0: no sequence named:idle
func_track_train must be on a path of path_track
