Vehicle check-in closes at 2:30 PM, no matter what traffic on I-95 does.
2:30 PM
Standard vehicle check-in closes, for a 4:00 PM departure
The deadline here is the cutoff, not departure: miss it and the car does not travel. Use 2:00 PM if your vehicle is oversized, a motorcycle, towing a trailer, or booked for priority offloading. Drag the deadline back half an hour and every row above it moves.
The Auto Train is the one Amtrak service with a firm check-in cutoff. Your car has to be handed over before the wall-clock time, not just before departure.
Same plan drawn to scale. The end block is handing the car over and checking in, with margin to reach the cutoff. Everything before it is the drive.
Front door to the check-in cutoff: 1hr 40min
You hand the car over, then wait in the terminal until boarding is called. The queue to check a vehicle in is the step that varies: arriving at the front of the window is a different experience from arriving near the end of it.

Amtrak advises two hours, which puts you at Lorton by 2:00 PM. The plan aims about fifteen minutes inside that, because the check-in cutoff is firm: 2:00 PM for oversized vehicles, motorcycles, trailers and priority offloading, and 2:30 PM for everything else, against a 4:00 PM departure. The Auto Train is the one Amtrak service with a firm check-in cutoff. Your car has to be handed over before the wall-clock time, not just before departure.
Work backward from the check-in cutoff, not departure: 2:30 PM, not 4:00 PM. Then the handover, the queue, and the drive (35 minutes in the default plan). The leave-by moment is the first travel row.
It does not work that way here. Auto Train coach seats are assigned when you check in, and sleeper accommodations are booked in advance, so arriving early does not improve where you sit. Arriving early protects the cutoff, which is the only thing it needs to protect.
There is no later departure that day. The Auto Train runs once each way, so a missed check-in is a missed day. Treat 2:30 PM as the deadline (2:00 PM if your vehicle is oversized, a motorcycle, towing a trailer, or booked for priority offloading).
The cutoff makes it feel closest to one, but there is no screening and no boarding pass to collect. What you are making is a vehicle handover with a wall-clock deadline, and once the car is checked the waiting happens in the terminal. Budget for the queue, not for a security line.
Flying instead? The airport pages use the same kind of plan with security. Station not listed? The Amtrak leave time calculator has the same rows with your own numbers, and the wake-up time calculator runs it back to the alarm.
