Great question. Buffer cars, as far as I know, are generally empty. They are placed for the protection of the crew as well as the loads. In the event of a derailment, it adds some distance between the crew and the oil (in this case). Perhaps more important, it provides some space between the oil and a potential fire on the locomotives.

The buffer cars, common on tank/oil trains today. Are these just empty hoppers or filled with some retardant?
