You can't buy set wagons for Saxonia as you mentioned, but you can use any other wagons that you have in your Storage or buy in the Shop. Look at the attached screenshot: click on one of the wagon types I marked ("Set" wagons tab is active on the screenshot, and I have all wagons for it as I've already completed these contracts).

Hope this help.
