Actually, it would be logical to find the handbrakes set anyway, on all loose stock. AFAIK, at least in American practice, it is not allowed to leave a train secured only with air brakes, as the pressure will bleed away as time passes (actually, pretty quickly...). Thus, handbrakes have to be set.

That was the scenario for a rail tragedy here in Canada last year in the little town of Lac Megantic, Quebec. A train carrying crude oil was parked at the top of a hill for the night; the engine driver set some hand brakes and left the engine running, then checked into a motel for the night. There was an oil fire in the locomotive, so the firemen killed the diesel engine when they put out the fire. Someone called the driver and told him not to bother coming back. Later, the train started rolling (it looks like the brake pressure bled off), went down the hill, broke apart in the middle of the town, exploded and burned and destroyed most of the town and killed 42 people. The driver has since been charged with criminal negligence, since it appears that he set the hand brakes on only about 5 of the 74 cars in the train.
