Hi Rod and welcome to the Trainz forums and to Trainz. You were lucky to grow up with that kind of traffic outside your front door. I had a small freight yard which my dad brought me over to see. This was a small local yard with a switcher which served a now extant paper mill on a branch off the main line. The through passenger and freights traveled between Boston and points west and north to Maine. We'd see parades of potato trains at one time before all that moved to trucks in the late 1960s.
Even though many of us show November 2006 as our start date, we've been here much longer. There was a very sad forum crash just before then which wiped out everything and we had to start from scratch. I've been here, for example, since December 2003 with others being here since 2001.
If you have trouble registering your software, or creating a MyTrainz account, contact the help desk via the button on the top of the forums page. They will contact you on Monday, or very late Sunday our time. The company is located in Australia and the support staff does not work weekends, although some members of their staff will visit the forums.
Presently we are experiencing some network or server issues which Bill (Hiballer) has explained in another thread. This has caused issues with downloading and updating content. The company is aware of the issue, and hopefully this will be sorted out soon.
Once you are able to connect to the Download Station, you will find a vast amount of content, perhaps 300,000 plus items which you maybe able to install into your iPad version. I'm not sure if all of it will work, given you have the tablet and not a PC or Mac version, which I highly recommend investing in. At the present time, the company is working on a totally new version called Trainz: A new Era, which we refer to by it's initials T:ANE or TANE. This is a version, which has been delayed, however, for good reasons and is being built from the ground up. If you have a PC or Mac, you might be interested in this version eventually, or even the current version TS12 as it does offer more content.
Anyhow, sit tight and once things are sorted on the server side, you should be able to download content. If you have any questions, feel free to ask and hopefully we can help you.
John
