This Mod is now being Mainted by D3x0r here: https://mods.factorio.com/mod/JunkTrain2 I officially give him permission to maintain, update and modify things as necessary.

Adds a new technology just after automation, that allows the creation of the slow but cheap scrap train, a low capacity portable chest variant of the cargo wagon and cheap but fragile Scrap rails.

The scrap train burns 200% more fuel and moves at a third of the pace of a vanilla train all while producing far more pollution, but far cheaper to craft and allows early rail systems to be set up.

0.1.0: Updated for 0.16! No other changes really, but check out my new mod Portable Chests!

0.0.8: Updated for 0.15!
