As an experiment I would suggest (but would never recommend) finding one of these routes and installing it. They are usually identified by having a thumbnail rotated by 90 degrees. But good luck with that.
It was a solid plan; I have attempted to download my TD2 routes to Trainz 2009: my only version of Trainz on PC. Failed of course, but the thing is though, the reason why it cannot be downloaded is very much unclear.
At first I thought that it might be a Build Version issue; as in Trainz 2009 is 3.3, and TD2 is 3.8— same as TS2 Mac (
I initially thought TD2 corresponds to TS12, since whenever I check on my routes via the My Content tab on the website, the website categorises my routes as 'Game Version: TS12' despite being made in TD2, and later on when I first attempted to download my routes via Trainz 2009 DLS, the Build Version of my routes were labelled as 3.8.). New Trainz can support old assets, but Old Trainz cannot support new assets; which causes errors whenever I attempt to download routes with higher Build Versions unto Trainz 2009, as according from what I have read from the distant past: Trainz 2009 may not support newer assets. So I'm thinking of shelling out for either TS12 SP1 or T:ANE as the Build Version of either version are close to, or above TD2's Build Version.
But then again, it could also be Version issue; as in Trainz 2009 is PC, and TD2 is Mobile. Therefore concluding any further hoping. But it shouldn't be an issue, because its visible in the DLS
— Now the Baseboard and Track thumbnails can be easily explained as I make TD2 routes myself: In TD2 surveyor, we can't change the Thumbnails, we can set the thumbnails, but only BEFORE our first save (
including autosave from experience). So that means we have to set up a decent layout in at least 15 minutes, enough for a good shot to make a good thumbnail. If we took too long, the autosave will take a thumbnail for us; If we Save And Exit (
TD2 has no 'Save' in the Main Menu, only 'Exit Surveyor' which may as well be 'Save And Exit'. There is a 'Save' in a sense, but its in the System Tab, a tab that is very clunky to navigate to, so I often just Save via 'Exit Surveyor'.), it will take a thumbnail for us, and its often the unflattering sorts with the baseboard and track. Why they're 90°, it just became a fact of life for us. It's awkward to see for sure, but we don't have much choice in the matter, we just make do with what is available.
—Sorry for the rambling, moving back; It shouldn't be an issue, because it's visible in the DLS. Yes N3V may just be using the DLS as a way for mobile users to safely save our routes (
Trust me: locally saving, as in depending on the game itself to save routes, is very hardcore; I've had crashes that corrupted routes, corrupted routes can't be uploaded to the DLS and therefore doomed to obscurity. And that's in an iPad series, a popular device to play TD2 in.), but if that're be the case, and Trainz Mobile routes are exclusive only to other Trainz Mobile games and users, then it shouldn't ever appear to fellow PC users, the same way PC routes are hidden from Mobile users, and yet it is visible for PC users, and unless its an oversight and/or coding limitations (
which may very well be the case as far as I know.), it implies that Trainz Mobile routes are compatible and can be downloaded for Trainz PC, given that certain assets may be missing due to Mobile Exclusive Routes & Assets if such exists. Or, all of this positive reasoning may just be optimism talking, and TD2 routes are in fact incompatible for PC use. Honestly I don't know anymore.
In short; Experiment gave inconclusive, unusable, useless, unworkable, moot, fruitless, and vain results. The test download error can't be determined if its a Build Version issue, or a Version issue.
If I came as a pestering sort, I'm really sorry. The ability alone to play Trainz on PC excites me: being able to do cinematography, and BIG screen, still had to get used to Trainz 2009 surveyor, but to also have the hope to play the routes I've made from Mobile to PC with improved graphics, and do cinematography while at it, well its basically a dream realised to life. Maybe later on I'll find a definitive answer but for now, my Mobile Routes are basically Schrödinger's. Again, I'm really sorry for pestering.
