Steam Sound Reed Switch Synchronization (Item # 584) Axle synchronization can also be accomplished by gluing one or two magnets onto any axle. The reed switch is supplied with two wires and heatshrinked inside heatshrink tubing. These merely connect to the White and Black wires from the "sync" connector. To create one chuff per revolution, which most will find creates the sound effect desired, merely glue one magnet onto the axle. For two chuff's per revolution, the second magnet needs to be glued onto the axle in the opposite position. Most trailing wheel sets are 1/2 the diameter of the main drivers, so two magnets would yield 4 chuffs per revolution of the main drivers. These magnets are very small and measure only 0.1" wide x 0.2" long x 0.045" thick. Two magnets and one reed switch assembly are included in this package.

Steam Sound Synchronization Optical Coupler (item #583) Using reflective infra-red light, this coupler reads axle pattern for true chuff synchronization (4 chuffs per revolution or whatever you desire). Packaged with the pickup is various laser printed stripes for mounting on a drive axle (various diameters included) or rim locations. This pickup is optional for all steam sound systems. The infra-red optical pickup has 16" of wire attached to it. Since only 3 wires are necessary between the engine and tender, our item 521 or 758 are ideal for this application.

Sound Controller (item #755) for ALL sound systems utilizing conventional DC or AC track power and our LocoMatic™ Systems. This unit connects between your throttle output and track power. Various features are obtained depending on the sound system installed. This only sends the message to the sound unit for what to play or do - it does not send the sound nor does it interfere with any track power. It is a "pass through device" when nothing is pressed or not powered. Therefore you do not have to remove it from any circuit when not in use. It also does not have any track power loss when wired into the track power circuitry.

If operation of our older sound systems is needed, you can either order the original two button controller, item #585, or for an additional charge, item #755 specifically made for the older and newer sound operations.
