issues with steam purchase

[scootes]

i recently purchased trs19 through the steam marketplace. i am having issues finding the seriel number so i can link my new trainz game with my existing account. I would like to use some of the dlc from this site but I cant download them without cd key. i have been playing the trainz series since the first edition this is the first time i have had issues with this part of it. any help would be great

regards

There is not a serial number. You must use the mytrainz account info you used to purchase the DLC to login from within TRS2019. Once you do that you will be offered the black Asset download window. Click download all to download all your DLC that is registered to your username. Any need purchased will show up in the same way.
