Model Train Rolling Road and Speedometer
TESTIMONIALS & ONLINE STORE click here or scroll down
The speedometer has an optical encoder that is connected to a shaft and rubber traction tire that makes contact with the locomotive wheel. The speedometer calculates the scale speed of the locomotive by measuring the rpm of the encoder shaft that is turned by the locomotive wheel. In effect, the encoder measures the distance traveled by the locomotive wheel, irrespective of the wheel diameter, and speed = distance / time. The AO Rail Speedometer also has wifi for downloading any firmware updates. The speedometer includes a power supply and operates completely independent of the DC or DCC system that is connected to the rolling road.

Testimonials
"Easy set up! When wired up to our programmer,
this makes speed matching a snap.
I wish I had this years ago."
- Dave, Southern Transcon Model Railroad
"Really enjoyed my time at Trainfest today! There were a ton of awesome new product releases, but to me, the best product was this test stand and speedometer readout from my new buddy Art with AORail.com. Anyone that's ever programmed a locomotive or had to troubleshoot one knows that the process can be tedious and frustrating. This stationary setup allows for fine tuning of the loco without needing all the space, and the speedometer readout is something we've desperately needed in the hobby!"
