ModelSpeed is a model railroad speedometer.

Ever wonder how fast your model trains are running in scale speed? Now you can find out.

Speed is calculated by measuring the time it takes to travel a known distance. On your layout or test track measure a section of track as accurately as possible. This could be the length of a bridge, grade crossing or simply pen marks. Just about anything you know the length of.

As the front of the train hits one end of the measured section, press the Speed Calculation button. When it reaches the other end, release the button. Your model train speed is displayed.

ModelSpeed comes in handy when trying to configure DCC speed tables. It supports F, G22.5, G24, G29, #1, O, S, OO, HO, British N, N & Z scales.

Train speed

I took a chance and very glad I did. I’ve been able to speed match all my DCC engines with good accuracy. I model N scale and recommend spacing your timing markers at least 36” apart preferably on straight track (but it does not have to be). You choose your distance and your scale and you’re all set.

Great App!

If you have ever seen a model railroad that looks realistic until a freight train comes flying by at what appears to be the speed of sound, you will appreciate this app. Like the other apps by this developer, it is very easy to use and an incredible bargain.

Handy, but only if the profiles were saved. You lose them when you exit and they have to be entered again. You can do what this does online for free, so I lost a $1. It was the profiles feature that made it worth the money for me, but I assumed they would be stored.

Update: the latest version saves the profiles and makes this well worth the price! Thanks for the update!
