Previously loved Thomas & Friends Super Station revolving round house tower station.   Interchangeable (from other Thomas & Friends kits) tracks  can be added.   Original kit with 35 feet of track retailed for more than $140. 
It’s assembled already (mostly because I didn’t know how to take it apart).  Has been in storage for some time and the dust will be scrubbed off prior to pickup. 
Thomas & Friends is a timeless character, storyline and program!
