installing Trains and Zeppelin Mod for Minecraft

So, my son would like to play this "Trains and Zeppelin Mod" for minecraft. Talk about complicated! I've got a mac which adds a little more complication. Anyway, here's how to do it:

1. go to terminal and type:
1. cp ~/Library/Application\ Support/minecraft/bin/minecraft.jar ~/Library/Application\ Support/minecraft/bin/minecraft_backup1.jar
1. this creates a backup of your .jar file
2. mkdir ~/temp
1. this makes a folder in your home folder called temp
3. cd ~/temp
1. this moves you into this folder
4. jar xf ~/Library/Application\ Support/minecraft/bin/minecraft.jar
1. this unzips the .jar file into the temp folder
2. download:


1. Modloader -> download file here
2. ModloaderMp -> download file here
3. Minecraft Forge API -> download file here
4. Trains and Zeppelin Mod -> download file here
3. unzip these zip files (double click on them)
4. copy, in the order downloaded, all the contents of these zip files to the ~/temp/ folder on your home drive
1. a dialogue box will appear saying something along the lines of:
1. do you want to overwrite this file
2. tick the "apply to all" box and click "replace"


5. finally, go back to "Terminal" and type:
1. jar uf ~/Library/Application\ Support/minecraft/bin/minecraft.jar ./
1. this zips the temp folder up into the .jar file in the right location

When the game is now loaded, it will tell you down the bottom left that there are 4 mods, and it should all work.

I had a bit of trouble before, but I've found I did things a little different then suggested. Heres some things I did different:

1. I loaded the game up after just installing the Modloader, ModloaderMp and Minecraft Forge API without the Trains mod installed.
1. I then went through the process again, and added the Trains and Zeppelin Mod
2. I didn't delete the META-INF folder in the .jar file
3. I couldn't find the trainconfig.cfg file.
1. turns out it is automatically made when minecraft is started.
2. doesn't look like this file works on Mac OS X 10.6.8?!
3. None of the Keys work!!!!!!

Hope it helps.

One note I'd like to make is:

• Why is this such a long winded process. The way I would like to add Mods is to:
• double click a file which loads and says it's installed!

But, I ask myself, why don't I do this. Well I guess I expect too much.
