Changing of the Faces:

the little known working hard face from one of the last trackmaster 1 sets that made a figure 8 with switch in the middle. was released around the same time as working hard diesel and cranky.

Never, ever seen that third to last Thomas face. It's not TrackMaster Revolution, so where's it from?

its a hybrid of the pre 2012 thomas with the animated face fitted. was available for a short time in some Trackmaster sets.
