@WindupGuy posted:Yes, Hafner. They used a bell clapper that was flipped by those tabs to ring the bell as the loco went around the track.
Interesting !!! And that reminds me that I saw a wind-up Hafner loco in a friend's collection, years ago, which had a simple bell clapper feature to work with this type of track. It also had a battery powered headlight, see photo.
Perhaps the track shown previously (Marx?), with a bump on each crosstie, was also for a noise-maker feature?
