Lowboy High-Centering Risk at a Passive Georgia Railroad Crossing
You are pulling a 53-foot lowboy hauling a track excavator, gross combination weight 78,000 pounds, on a two-lane Georgia county road. The route crosses a passive railroad crossing with no gates or lights, only a crossbuck. The crossing surface has a noticeable hump, and the trailer's ground clearance is about 7 inches. Sight distance to the left is blocked by a stand of pines until you are about 50 feet from the tracks. The road speed limit is 55 mph, and a pickup is tailgating you closely. The tracks run at a slight angle to the road, and the far side of the crossing leads directly onto a narrow bridge with no shoulder. A train horn sounds in the distance, and the crossing has a small blue sign with a 1-800 number.
1. How do you approach and cross this crossing, and what do you do about the tailgater?

Treat the passive crossing as a stop-and-check situation even though there is no stop sign. Slow early and gradually, using your turn signal or hazards to warn the tailgater. Open the window, turn off the radio, and look and listen. Because the pines block the view to the left until you are close, you need to be slow enough to stop before the tracks, not just slow enough to look.
Do not shift gears on the crossing. Select a low enough gear before you reach the tracks so you can cross without a gear change. Check that the far side is clear: the narrow bridge with no shoulder means you cannot stop just past the rails. Cross only when you can clear the entire crossing and get onto the bridge approach.
The tailgater is a secondary problem. Do not speed up or wave the driver around; slow smoothly and let the driver pass if they choose. Your job is to protect the space you need for the lowboy, not to manage the pickup's impatience.
2. The hump worries you because of the lowboy's 7-inch clearance. What is your plan if the trailer high-centers on the crossing?
Read the worked answer
Before crossing, assess the approach and departure angles. A lowboy with 7 inches of clearance can drag its frame or ramps on the hump. If possible, stop before the tracks and walk the crossing to see how the trailer will bridge the hump. In some cases, crossing at a slight angle reduces the chance of dragging, but only if the angle does not put you into the path of a train or off the pavement.
If the trailer does high-center, do not stay with the vehicle. Get out, move away from the tracks, and call 911 and the railroad emergency number on the blue sign. Give the dispatcher the crossing location and the fact that a lowboy is stuck. Do not attempt to restart or rock the combination while a train may be approaching. The priority is to clear people from the danger area and get the railroad to stop traffic, not to save the load or the schedule.
3. A train horn sounds and the pickup behind you pulls into the oncoming lane to pass as you slow. What do you do?
Read the worked answer
Maintain your lane and your speed control. Do not follow the pickup onto the tracks just because it is passing; the driver may be trying to beat the train, and that does not make the crossing safe for you. If the crossing is clear on the far side and you have already committed, keep moving steadily across without stopping. If you have not entered the crossing, stop before the stop line or the edge of the tracks and wait.
Do not swerve to block the pickup or to avoid it. The oncoming lane may be your only escape path if something goes wrong, and a sudden steer with a lowboy can swing the trailer or drop a wheel off the pavement. Sound the horn if the pickup is creating an immediate hazard. Keep your attention on the tracks and the far-side bridge, not on the other driver.
