Requires a two-person crew minimum for railroad trains or light engines used in connection with the removal of freight

HB 3349 requires railroad trains or light engines moving freight to operate with at least two qualified crew members, excluding helper services (assisting trains), hostler services (yard locomotive movements), or slow-speed loading/unloading (under 10 mph). Violations incur escalating fines: $1,500 for a first offense, up to $10,000 for third or subsequent offenses. The Missouri Department of Transportation enforces the rule, but the law only becomes effective after Missouri's attorney general confirms federal courts have validated the Federal Railroad Administration's two-person crew standard.
