Stuck Gate at a Rural Railroad Crossing

A driver hauling a 53-foot dry van approaches a rural crossing at 10:40 p.m. The crossing has flashing red lights, a bell, and gates. The gate on the driver's side is raised and appears stuck at a 45-degree angle; the gate on the opposite side is down. The red lights are flashing and the bell is ringing. The driver sees no train, but the track curves through a tree line about 300 feet to the right. The trailer is 13 feet 6 inches high; a sign says "Low clearance 14 ft" at a bridge beyond the crossing. Traffic behind includes two cars. The driver's route requires crossing to reach the terminal 12 miles away. The driver has a cell phone but no railroad emergency number posted.

1. What do the signal indications require you to do, and why doesn't the raised gate change that?

Read the worked answer

Flashing red lights and a ringing bell mean stop and do not cross. The gate is only one part of the warning system; a gate stuck at 45 degrees is a malfunction, not permission. The opposite gate is down, which is consistent with an active warning. The driver must stop before the track, avoid blocking the crossing, put on flashers, and call 911 and the railroad emergency number (usually posted at the crossing or available through the sign). Do not drive around or under a gate. No visible train is not proof: the track curves through trees 300 feet away, and at night a train can be hidden until it is too late. Cross only after the signals stop or a police officer/railroad employee authorizes movement.

2. If the driver is certain no train is within 300 feet because of the curve, can they cross after stopping?

Read the worked answer

No. A 300-foot sight distance is not a safety margin. A train at 40 mph covers 300 feet in about 5 seconds; at 60 mph, about 3.4 seconds. The curve hides the train until it is close. The warning system is designed to activate before the train reaches the crossing, so flashing lights mean a train is approaching even if the driver cannot see it. A driver's 'certainty' based on a quick look is not enough. The correct action is to wait, call, and cross only when the warning stops or authorized personnel direct the movement.

3. What should the driver do about the schedule and the traffic behind?

Read the worked answer

Put the flashers on, stop clear of the track, and notify dispatch and 911. The cars behind can wait or pass only if it is legal and safe; the driver should not wave them across the track. Document the time, the signal condition, and the call. Ask the terminal for a delay code or alternate route if one exists, but do not invent a detour that crosses the track elsewhere without checking that crossing. If a police officer arrives, follow their direction, but do not cross until the warning system is confirmed safe or the officer controls the crossing.
