I think the error is pretty self explanatory if you care to read it.

java.lang.IllegalArgumentException: Slot 253 is already occupied by TrainMod.Blocks.BlockDistil@3736ac when adding mffs.BlockMachine@e664ac

Chances are you can just go into the config file for your new zeplin trains mod and change the itemid for item 253
