I just dug out my Train Talk EOT modem, and started looking at passing trains. Many more Cab messages than EOT messages.

A lot of the traffic past here is Coal Trains, with multiple power - not uncommon to have head, middle, and rear all be multiple engines.

So, that got me curious, how do they control the other engines? I presume that RF is involved somewhere.

Thanks
