You need to update IC2 Nuclear Control to 1.1.11 to fix this. It is a known bug.

I agree.

Replace the buildcraft/api folder in the railcraft zip with buildcraft/api in the buildcraft core zip.

Replace the buildcraft/api in the railcraft zip with the buildcraft/api in the buildcraft core zip for both the client and server.

I have never had this happen before. Is there any other log anywhere?

use MCEdit of mIDas to remove advanced machines and rock crushers. Also update to IC2 Nuclear Control 1.1.11

Replace techniclauncher/tekkit/mods/IC2NuclearControl_client_v1.1.10b.zip with http://goo.gl/u6DqD and server/mods/mod_IC2NuclearControl-1.1.10b-mcpc-r1.zip with https://github.com/downloads/mushroomhostage/ic2-nuclear-control/mod_IC2NuclearControl-1.1.11-mcpc-r1.zip. As for MCEdit, look up a tutorial because youtube has done a way better job explaining it than I will ever be able to.

No problem

1. Replace the buildcraft/api in the railcraft zip with buildcraft/api in the buildcraft core zip. Then use MCEdit to remove rotary macerators, singularity compressors, centrifuge extractors, and rock-crushers. 2. Don't use tekkit for single player anyway, technic is better.

This is not a problem with tekkit. I have had this without mods before.

Check the techniclauncher/logs/launcher_0.log file for the error log.

Replace the buildcraft/api in the railcraft zip with the buildcraft/api in the buildcraft core zip for both the client and server to fix the error you had after removing advanced machines. Rock Crushers will also have to be removed FYI.

Replace the buildcraft/api in the railcraft zip with the buildcraft/api in the buildcraft core zip for both the client and server. Worked for me and two friends, and other random people on the forum so far.

Use mIDas or MCEdit to remove advanced machines. As far as I know there is no other way to fix this.

Using my fix above still leaves IC2 Nuclear Control (Just update this to 1.1.11 on client and server), Advanced Machines, and Rock Crushers broken.

Replace the buildcraft/api in the railcraft zip with the buildcraft/api in the buildcraft core zip for both the client and server. That will fix the current error log you have. You will get another one if you don't update to IC2 Nuclear Control 1.1.11 for client and server. You will also crash if you have advanced machines or rock crushers. Remove those using mIDas of MCEdit.

If you have Rock-Crushers, the server will still crash because Rock-Crushers use the new api. Try using mIDas or MCEdit to remove all Rock-Crushers.

What exactly are you doing? I can't reproduce this.

Due to copyright, I can't redistribute railcraft. This fixed this for me and three of the friends. The exact steps I took were... Server 1. Extract "Railcraft-5.4.7-MCPC-1.2.5-r7.zip" and "buildcraft-2.2.14-mcpc1.2.5-r8.zip" 2. Delete Railcraft-5.4.7-MCPC-1.2.5-r7/buildcraft/api 3. Add buildcraft-2.2.14-mcpc1.2.5-r8/buildcraft/api to Railcraft-5.4.7-MCPC-1.2.5-r7/buildcraft/ 4. Compress ALL the files in the Railcraft-5.4.7-MCPC-1.2.5-r7 folder that was extracted. 5. Rename the new archive "Railcraft-5.4.7-MCPC-1.2.5-r7.zip". 6. Paste the new archive into the mods folder and delete the extracted folders. Client 1. Extract "Railcraft_Client_5.4.7b.zip" and "buildcraft-client-A-core-2.2.14.zip" 2. Delete Railcraft_Client_5.4.7b/buildcraft/api 3. Add buildcraft-client-A-core-2.2.14/buildcraft/api to Railcraft_Client_5.4.7b/buildcraft/ 4. Compress ALL the files in the Railcraft_Client_5.4.7b folder that was extracted. 5. Rename the new archive "Railcraft_Client_5.4.7b.zip". 6. Paste the new archive into the mods folder and delete the extracted folders. SCoFF3D, your error is due to advanced machines using industrailcraft 1.93s API. Remove all rotary macerators, singularity compressors, and centrifuge extractors. in MCEdit or a similar program. I have not found a simple fix for this; I think it will require a recode.
