TUGS was Thomas the Tank Engine and Friends's sister show. Thomas and Friends used some of the TUGS models after the latter was cancelled, such as the ocean liners, Lakesider III, the Salvage Barges, the Brendam crane, the tugboats, and the Fultan Ferry. Some of the models' likenesses made it past the switch-over and are now seen in CGI.
- The China Clay Trucks used in Season 2 of Thomas and Friends were later used as Goods Trucks pulled by Puffa and the Goods Engine in TUGS.
- In December 2012/January 2013, members of SiF purchased most of the original TUGS models and formed The Star Tugs Trust, which aims to restore the models.
