A school bus stalls and becomes trapped on the railroad tracks. What should the driver do?

AAMVA CDL Manual Section 10.4.4 (Bus Stalls or Trapped on Tracks), p. 10-9; 49 CFR Part 380, Appendix D, Unit D1.5 (Emergency Exit and Evacuation) and Unit D1.6 (Railroad-Highway Grade Crossings)

Every second counts once a bus is stuck on the tracks, and the direction people run matters as much as the fact that they run. Moving away from the tracks at an angle toward the oncoming train, rather than straight back or in the train's direction of travel, is the specific guidance meant to keep evacuees clear of a collision and its debris.
