Hi guys, I hope I'm asking in the right place, but I have a question regarding Trainz for Android devices. I have it for my Kindle Fire, and I was wondering something, can I get add-on's for it? Such as that site with the USRA engines? And, what are the limitations to it?

P.S. For all msts users reading this, no I'm still a msts man. No offense to the Trainz guys .

Thank you very much,
