As a Conductor, Locomotive Engineer, Signal Person or other signal related professional in the railroad industry it's important to always be able to recognize the many railroad signals and signs. This app will help you do just that. It contains the standard NORAC signals and signs as digital flashcards allowing you to study anywhere at your own pace.
The R.D. Murray Signals App is not just a digital deck of flashcards, it's also a testing system that allows you to improve you signal recognition ability by giving you a variety of ways to test your skill including a timed test. You can even post your score on a leaderboard and compete with your friends.
There's also a section on important NORAC operating rules which we update periodically.
With signals, signs and rules all accessible right from your smartphone, you'll always be on top of your game anytime and anywhere.

This app is constantly being updated.
We're working on adding leaderboards, better graphics for signs and other cool features soon.

Please let us know what new features you'd like to have in the R.D. Murray Signals App

Great App For A Railroader!

It’s a really refreshing app that makes it easier to study up on your signals, rules and compliance. I do wish that it had GCOR signals, though.
