They made a total of 3 of these sets:

this one has track master tracks and was the original building with Jeremy instead

this was a road and rail version

And your version was a limited edition 60th anniversary set which had a medium to small-ish run time

The mechanism used in the building is similar to Harold's. Hope this helps .
