Add multiple receivers to your existing Rolling Thunder setup so you can simultaneously hear multiple locomotives (and accessories) through your Rolling Thunder system!

Since each Rolling Thunder receiver locks onto a single locomotive at any given time, if you want to have multiple locomotives sound through your subwoofer at once (while double heading, for instance), you'll need to combine the signals from multiple receivers into a single cable going to the subwoofer.

This cable allows you to do just that. In addition, BLI have some exciting new accessories that utilize the Rolling Thunder system, and this cable enables their use as well.
