That's "the mighty sound of beans"(my term) from the 1980's used with some low-end set locomotives.

You're quite right, there's a bunch of plastic "beans" inside the cylinder that shuffle around as it rolls on the third rail, creating a chuffing (by a long stretch of the imagination) sound.

It tends to sound more like a rain stick with hiccups.
