Smudger, one of the one-appearance characters from the show NEVER had a Trackmaster model. He will likely not have one after when the range redesigned in 2014, and renamed to Motorized in 2020.
However, It's possible to make a Trackmaster model of Smudger because he and Rheneas have the same shape. That same goes to all other toy models of Rheneas. Including but not limited to Take-Along, Bachmann, Bandai TECS, Nakayoshi and Capsule Plarail.
