In the official Support forum tehy said its only possible ingame

Note 4: Downloading items directly from the Steam Workshop via the Web instead of the game is NOT recommended just yet - Please Use The In-Game Content Manager instead.

but its not running, i think there is a bug?

yes there is a big bug !!! I have posted a thread in the general discussion.

I think I have a solution for you. After uploading the items via Steam-Workshop (subscribe) you have to start RCTW and go to the "Community-Menu" (there you are able to active your items).

That seems a little excessive to get content items from the Workshop. You don't need to uninstall the game, and you definitely don't need to uninstall Steam. That's a lot of unnecessary work.
