What is the procedure to go into Surveyor, and pick a locomotive to run in Driver Mode? I downloaded some NKP Geeps and would like to run them. I am new to this and I'm using TRS2006. I found the NKP unit in the spoked wheel thing, and I've clicked Conrol F2, but it says I have to install a train before I can drive. There are not many US Routes to chose from, and other than the Country/City and Tidewater South, what other scenarios are there?
