Due to the train tracks placement being in increments of 2 and inserters moving in 3 or 5 it is often a pain if not just impossible to load from train to chest to train without using belts.

If you made your chests 2x3 and 2x6 this mod would be awesome for use with trains.

I never had this problem, I'm simply using one row of 6 stack inserters on each side of train. Using stack inserters the whole train in unloaded in 10 seconds and that is good enough for me.

This mod was created because if only one chest was empty the unloading process would be 6 times slower.

Anyway, I dont intend to do any chests that are 2 high.

I think you miss understood my idea!
Yes there is never any problem with 1 Train stop it is when you try to unload from 2 Train Stops side by side.

Anyway the Warehouse Mod does this very well :)
