Crash Report
It seems that there is an issue with Railcraft and ElectriCraft. As stated in the post HERE that you would need full logs to see what is happening, I have linked them above. This is the smallest set of mods I can get to have both Railcraft & ElectriCraft.

So... the only coremods inside that could mess up are DragonAPI and RotaryCraft...
@ReikaKalseki Is either of those mods shipping the BuildCraft API or parts/individual classes of it?
@bookerthegeek could you try adding BuildCraft and see if the crash still occurs?
Buildcraft 7.1.14
DragonAPI 1.7.10 V10d
ElectriCraft 1.7.10 V10b
Railcraft_1.7.10-9.8.0.0
RotaryCraft 1.7.10 V10d
Modpack loads up as expected with no glaring issues.
@bookerthegeek As expected. Thanks for the investigation.
@Vexatos May I ask what the resolution is? I am curious as to what the original issue is in a very non-finger-pointy kind of way. Mainly so I can figure out how to solve it easier next time.
@bookerthegeek Usually FML tells you in the log which .jar file an API is loaded from if multiple jar files are shipping it. Railcraft crashes because it cannot find the Wrench API class. FML, however, says that it did load the API from the Railcraft file which most definitely contains the Wrench class unless someone tampered with it. Adding BuildCraft fixes the issue because it guarantees the API is there in its entirety.
Would you mind checking if the file buildcraft/api/tools/IToolWrench actually exists in the Railcraft jar file?
@bookerthegeek So the class was there, supposedly detected by FML... But couldn't be loaded. This is a really strange issue.
But... Railcraft is shipping the BuildCraft Tools API. It is even the one actually loaded by FML...
@Vexatos Can you reproduce in your environment?
Can you push a version with more logging options I could run for you?
The problem is an FML classloading error, and there is no fix outside of simply copying the classes into the DragonAPI jar.
