While looking into the traincraft mod for my SSP world I discovered something cool and totally game breaking. It turns out thanks to traincraft it is possible to turn 24 iron, 8 coal and a clay ball into 64 steel with 0 exploit. This is done via its built in steel recipe on its train workbench and the steel can be used in all recipes that use steel thanks to the ore dictionary. Which means their is no point in building a blast furnace that has a 1 to 1 ratio when you can more than double your steel production via traincraft. To make matters worse their is no option to disable the recipe in its config and the recipe is done on a non-standard crafting table so disabling it will be very hard with out disabling the whole mod.
Here are the recipes - http://trains-and-zeppelin.wikispaces.com/Recipes
Note that you will only get 32 steel dust but when you cook it in any furnace it will double it and even net you a good bit of xp if done in a normal furnace.
Edit - It also appears that all the train craft recipes will allow you to substitute refined iron for its steel so if a way is found to disable the recipe then it will not break the mod.
