    I'm about to take my signals test in a couple of days. I didn't verify the signals but as far as I can tell they look legit. Some of the questions had the answer multiple times and that is something I would change. Also a previous person commented about indication test. This would make this app awesome. The worst thing about this app is the rules test because rules change all the time and It would be a full time job keeping up with all the changes. Once again thank you for this app. Full Review

    Good overall, but would be even better if users could edit which signals they are tested on. I currently don't need the color position lights and would like to be able to remove them. Full Review

    It's perfect for whenever you have down time and want/need to study your NORAC signals. I really hope more rule books will be added, such as Metro-North and GCOR. Full Review
