If my understanding of "dynamite" is correct, it involves the use of the reverse lever while the train is in motion. It could be done on steam, but I'm not sure about diesel. No matter what, it would be hard on the equipment.

Elliot,
A dynamiter is a car with a bad brake valve...the slightest brake application causes it to blow, and puts the entire train in emergency...the bad part is you cant find it easily...you have to pump up the air, walk a bit, and have the engineer draw off some air, and hope you can hear which car bust first...you have to do this several times, walking down the offender...because the air will bust from the bad car both ways, forward towards the locomotive, and back to the rear... if you hear the air going away from you, you walked too far....coming towards you, you still have some walking to do!

Once you find it, you can cut that brake valve out...and the train line runs straight through that car.
First chance you get, you have to set it out bad order at the nearest repair facility...

Thanks Ed, I hadn't heard of that usage. Air brakes aren't something that comes up in the modeling world. The flying switch move is at least heard of, but can't really be performed because of low mass on the car, and and the way model couplers work. [;)]

Actually your search method for the bad car reminds me of looking for an electrical short in Lionel track. Both equally annoying and difficult to find.

On my OSL dutch drops use to be done but The UP who now owns the line has decleared them illegal and they are illegal. Out here on the Nampa Sub of the OSL we have industries that haul hazmat and where I live in Bliss it is no exception. We got a cold storage wearhouses, we got an oil refinery, we got grain elavators,we got silage unloading, and we have a cement plant and they don't want their freight damaged. You don't go dutch drops on the OSL lets take Bliss for example Hulcum Cement delivers car loads of quicklime to Bliss and loads empties with coal ash which is delivered by truck origonal these cars were dutch dropped but today with better crews they pick them up and hook them to the train avoiding dutch drops. Another facility is Lancing Grain they pick up and load grain here and those cars are 90 tons full loaded you don't dutch drop them. In Glenn's Ferry and Gooding we have cold storage one of them is owned by WEL trucking and Glambia Cheese who interchanges refergertor cars with the Union Pacific Fruit Express every thursday and they like their cars undamaged. On the south side we have Agratec who gets car loads of silage and United Oil's Gooding refinery and they don't like their cars smashed. also in this area is Glambia's rail dock and the Gooding branch of Lancing Grain and they don't want damaged cars. This is why a dutch drop is illegal.  Cars are pushed down a hill a switch is thrown and the cars are braked. which can cause flatspots or worse derailment.
