Railroad Crossing Sound Effects Circuits


Our MRB2 bell/strobe circuit is no longer available.   MRB2 Installation instructions [pdf]
 
To ring a mechanical bell, the Circuitron BR-1 or BR-2 may fit your need. It is available from Walthers and other retailers: Connect the BR-1 circuit to the Azatrax D2T-Xing or MRX3 crossing control circuit like this:
BR-1 to D2T-Xing
BR-1 to MRX3
 
 
Electronic sound effect modules that play through a speaker can be triggered by our MRX3 grade crossing signal controller and by our D2T-Xing grade crossing signal controller.
 
These diagrams show how to connect an ITTP GL sound effects circuit. Sound modules from other manufacturers can connect in the same way.
sound module to D2T-Xing
sound module to MRX3
 
An Xbell sound effects module from Iowa Scaled Engineering can be connected to our D2T-Xing grade crossing signal controller or to our MRX3 grade crossing signal controller like this:
sound effects connections to D2T-Xing and MRX3
Use MRX3 terminal SB for short duration sound effect, or terminal LB for long duration sound effect.
