Introducing the most realistic throttle for
operating model diesel locomotives – the ProtoThrottle.
With the ProtoThrottle, modelers can operate just like a real
engineer because the controls feel and perform
just like the prototype.
The ProtoThrottle is a wireless controller that works in tandem
with your DCC system. It features an aluminum anodized faceplate,
fully detented throttle handle with 8 notches plus idle, fully detented 3-position
reverser handle, smooth resistive brake handle, spring-loaded
horn handle, and many other features.
Currently supported DCC systems include NCE, Lenz, ESU CabControl,
Digikeijs DR5000, JMRI WiFi Throttle, and Digitrax (via an LNWI module).

The ProtoThrottle is being developed as an Open Source project through
Iowa Scaled Engineering. To learn more about Iowa Scaled
