I am new to the mod so sorry if this is a stupid question. I see two engines tied together in screen shots and videos. I have played the the mod but I don't see where the option is to use them. Can any one here point me in the right direction. Thanks for any help you can give me.
OK. Let's go back to your first post.
Apparently you are looking for a way to have two engines permanently in your game setup and have it ready for your use just with one click of command.
If that is the case: it is a big NO-NO. While it could be done it would require permanently revising the original Firaxis game setup, and that is not recommended. Experts of this game strongly advise against changing anything that is in the basic installation files.(C:\Program Files\2K Games\Firaxis Games\Sid Meier's Railroads!)
You have to do all your modifications in C:\Users\user\Documents\My Games\Sid Meier's Railroads!
Directory on a case by case basis. That is you have to have a scenario (new map) that you want to have and can have duals, but if you want have them in an other map you have to transfer them (copy and paste) manually to the other map.
I suggest that you download and play the Amerigona map by Dr.Frag:

It has all the duals. That's where I have learned from how to make them.
Good Luck!
