Mike's Railroad Crossing Forum

This level crossing is located in Castelnuovo Calcea (Asti, Piemonte - Italy).
We filmed it up late in the afternoon with the barriers down, stop signal switched on, train passage and the lift of the barriers.
Another video of this level crossing by night with the passage of a freight train is available here: https://www.youtube.com/watch?v=vSPOxHmZ3QU

What was going on with the light? Looks like it could have something to do with the frame rate of the camera?

No, it's just the stop light. In Piemonte some level crossing have the same particular characteristic of light.
