If you have not yet registered the serial number, we recommend doing so to enable your forum icon and DLS access. If you have already registered the game to your account, you will be able to find it in your MyTrainz > Serial Number page. You will need to locate the appropriate item on the page, and the serial number will then be shown along with the download link. For items that require a serial number or Product Key, these will now be found in the My Digital Downloads page in your MyTrainz account.
