This is a demonstration on how to make a moving subway tunnel, made by func_trains. Nothing new, but i think this is better than the conveyor method.
EDIT: sorry but the .bsp need some other wad; tomorrow i'll update with textures embedded.
Anyway the .rmf can be opened and the textures replaced.
Shadows are correctly rendered, creating the illusion of real-time lighting.
In Poke646, a combination of both methods was used, resulting in a very good trainride level. The subway tunnel was made with the conveyor method, while architectural details like lamps and signs were done with func_trains.
So, I don't think this method is 'better'. It's just more usefull in some occasions...
But with the method i used you can add more variety, you can make a door into a part of a wall, vents in the ceiling...
Anyway yes, it depends from what it has to be done, btw, the func_conveyor method require less work, and less entities.
Sorry but the site give me an error if i edit the map; i cant'upload a new version.
