The AskRail app is a hazardous materials safety tool for first responders who are first on scene or directly support the first on scene in the event of a rail incident. Access to certain features, including the ability to query railcar contents based on an equipment number, is restricted to authorized personnel. To obtain authorization to use the restricted features, you must assert that you are a first responder, provide information about your emergency response agency, and identify a supervisor who can attest to your first responder duties. You also must obtain sponsorship from a Class I railroad. This process may take up to several weeks. AskRail is a collaborative effort among all North American Class I railroads, the Association of American Railroads, Railinc Corp., and the Transportation Technology Center, Inc.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
FAST holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: AskRail has 37 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 58% of AskRail's written reviews are positive against 0% of FAST's, so the app with the better star average is not the one people write more warmly about.
AskRail ships an update every 4 months, FAST every 7 months. The most recent releases landed on October 3, 2026 and September 17, 2026 respectively.
