Are the RailSounds started by the motion of the train?
I could be wrong but I vaguely recall only two Railsounds that depended on the motion of the train.
The first was a primitive CHUG/CHUG/CHUG/CHUG sound made inside a big black plastic wheel concealed in a tender. It contacted the center rail and turned as a train moved forward or backward. Partitions inside this wheel accumulated small pieces of material
(beans, one guy told me), raised them, and let them fall down, making CHUG sounds (more or less). Marx may have come up with this one.
The other was a contact near the bottom of a smoke unit. When a crosshead moved a smoke lever up, the contact closed and made a hiss of "white noise" that resembled a CHUG as a locomotive moved faster. The speaker was in the tender.
