Well, after a number of unsucessful attempts to make a control house, I went back to my old PC-because it's XP, not vista- and installed Sketchup and the trial of Sketchup pro. I made a mediocre first attempt of a station control house and it looks ok. I'm still working on it.
I'll post a picture as soon as I can.
Trackwork Update:

I'm getting close to finishing the track. After that, I'm adding a few more hills to the landscape and adding some palm trees around the track. I hope to upload it by Sunday if all goes well.
