What DLC do I own ?

[Cardinal51]

I there an option in TS2012 / Steam that shows me the Steam-DLC I bought / installed ?

Start Steam if it is not already running. Login, if necessary. Click on xxxxx's account where xxxxx is your username in the upper left corner of the display.

You should see a listing of all your steam purchases/downloads.

Go to your Library on Steam:

Right click on Train Simulator 2012 > Click on View Downloadable Content.

Thanks guys, will check it out in the morning.

Also (and better) to check all your installed assets (not only Steam DLC):
RWTools | Route Building Tools | Check Routes or Scenarios | Print list of all Routes and Scenarios... and yer done!

Thanks for the help guys !

Just checked Steam , using your tips, and I saw the list.

I have proof now. Got another copy of TS2012 (gift for someone) for as little as 3.6 US$

Print list of all Routes and Scenarios... and yer done!

Will that also tell me what DLC I have from steam. Or does it just list everything ?

was my mistake, this list is not usefull for what you want. It's just a list of all routes and theirs scenarios, not of all assets (and also doesn't have origin: Default, DLC etc.).

When trying to buy a DLC pack that you already own, you get a green banner saying that. That's the way I check (confirm) that I already own the pack.
