I'm getting it from World of Trainz, payware. So I'm not sure if its a zip file or cdp. When I click on the link it goes to open w.o.t. page then stops loading. I didn't wanna mention where I got it from cause I don't wanna people to think his stuff don't work. I had the same locos when I had xp but now this windows7 thing is a whole different world, well for me it is anyway. I e-mailed him back but he hasn't gotten back to me yet.
