The Meaning of Life, the Universe, and Everything.
It says here on the traincraft wiki that railcraft loaders and unloaders (also including liquids) can work with traincraft: http://trains-and-zeppelin.wikispaces.com/Tank carts
So I put the unloaders 1 block above the holding track like the wiki says, and how its supposed to work with railcraft. I make a railcraft cart come along works fine, it stops, loads up and goes off. Then the traincraft train comes along (i did make sure i changed the holding track to train holding track) and it just keeps going, it doesnt stop or anything. What can I do now?!
