Rule 80 is not properly copied, so if you are required to know it verbatim good luck. Horn/communicating signals are just not even remotely accurate and are certainly not taken from NORAC, as i remember in the app 4 shorts on the horn was a horn test? Signals are okay but you won’t hit them all. ### 1/5 — Can’t even go to the rules or horn test *2022-02-17, version 1.701* Throw it in the trash start over man like it’s no way I’m pressing my option and it doesn’t click like where we do that at pop get it together ### 2/5 — Needs a update *2020-05-01, version 1.701* App needs a update take too long to start and the only one that work properly is the signals would like to practice signal progression and horns and the others but not coming up ### 5/5 — Great App For A Railroader! *2018-04-19, version 1.213* 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. ### 5/5 — It's about time !!! *2018-02-18, version 1.0* Long over due, great app. ## Frequently asked questions about R. D.
