Is this a scene from this series?

There is a movie or TV series I saw in the early 1960s that opened with a scene of a car stopped at a railroad crossing. The signal bells are clanging as a train is rapidly approaching.

The driver gets out of the car and pulls a man's body (or maybe he is unconscious) from the back seat and drags it onto the tracks. The impression I got was that the driver was a killer trying to make a murder look like an accident, set up so that people would think the victim died by being hit by a train. The man makes it back into the car just before the train comes into view, before anyone could witness his actions.

I thought this might have come from a Perry Mason episode since it was on the air around the same time period, and my dad never missed an episode of that series. I asked at the PM board and nobody recognized it.

Does this sound familiar to anyone?
