OK let's start at the beginning. One presumes you got the thing unzipped and have something that looks like this.

The only issue is if you do not have a LukRailAmerica folder the child object will not go into the proper place. If that is true you need to take the LukRailAmerica folder and put it into your Assets THEN go into it and make a new folder named Child. Then cut and paste the ET44AC folder into that. I think he was assuming that you already had a child folder inside the LukRailAmerica folder. I did because I had these plows already in there. Note the path and what this looks like. You may not have the plows.

Now you need to copy and paste the the ET44AC from the RSC section into the PennCoal\RailVehicles\Diesel\ES44AC folder. Again check the path to see that it looks like this. You should have something that looks like this:
RSC ET44AC into ES44AC.jpg
Now as per the instruction find the ES44_Default.GeoPcDx in the default Engine folder and copy and paste it into the ET44AC Engine folder.
Make sure and check off the LukRailAmerica child box in the Assets list and SHAZAM!
