In the wake of the East Palestine, Ohio train disaster the AskRail mobile app has been discussed in a number of forums.
AskRail is an app for all public safety users. It’s a free app that at the VERY least offers phone numbers to all the rail car safety lines – however its primary purpose is to identify train car contents.
When the car’s code is entered, the app shows what is in the car, how full it is, if it is empty, what was last in it, and more. If the code of the car in question is not visible – choose another car in the train. It will show all of them, and run isolation maps.
