-Got your PM. I have to say, I am no different than anyone else here. I don't have the time. Trainz doesn't come first in my life and it's just a hobby. Trainz doesn't pay the bills. I don't even get the chance to open Trainz on a daily basis, maybe every other day if I'm lucky. What I'm about to say is going to sound repetitive cause everyone else has already told you but I thought I'd put my two cents in before I have to sleep and go to work tomorrow...
-I started with Trainz 2006, just messing around for years. I started to get serious when I wanted to create a real prototypical route, the Mojave Subdivision, in which I believe I started it in Trainz 2009/10, which everyone knows now is default content in Trainz 2012. Everything was not easy. I had to learn Transdem just to get the ground made and ask anyone who has used it, it is a steep learning curve. After working on it for x amount of time, posting pics, it looked good enough that Jointedrail liked it and picked me up and put me on their team. At this time I knew nothing about 3ds Max or Photoshop. I think one of the very first things I created was the tunnels on the route. Anyway, I pretty much self taught myself both programs, with JR's help, by reading and watching YouTube videos. While I was with JR I asked them, a lot of questions, bugged the cr*p out of them, to the point they wouldn't even answer me, but I never gave up and eventually ended up finding the answers I needed. Point is, if you want something bad enough, you'll have to go get it yourself.
-I have my Cajon Subdivision to work on, which is much larger than the Mojave Sub is. Since some time after finishing the Mojave Sub, life took a busy turn for me and I left JR. I am a one-man-army, just like many others. I even have to take long breaks at times, so long that I forget or loose some of my knowledge on how to do certain things. I have hundreds maybe even a thousand or two of dollars invested in programs, both routes, more with Cajon. I even took a vacation, road trip to California to take pictures, purchase information from the San Bernardino Station, etc. Bought many dvd's, timetables, purchased grade charts, Transdem wasn't free either, it all adds up. I want Cajon to be the best of the best, but it's just not going to be and it's never going to be 100% exact and you need to come to terms with that with your route or future projects.
-My advise, just like others have said, learn! If you want a prototypical route, it's going to take time. Work on what you can now, then go back and replace what needs to be replaced with yours or others custom assets. I can keep on rambling on about this and it probably doesn't even make any sense but I am tired. Good luck on your project. Take your time. Take breaks. Learn programs.
