tank cars behind locomotives

There are little to no fumes from crude oil and although it burns, it's not so easy to set on fire. From this forum I've learned that the fuel oil used in steam locomotives is even more difficult to set on fire. Ed Mines

I think you have to remember that there are differing grades of crude oil. The Canadian oil train disaster happened in part because the shipper didn't let the railroads know that the North Dakota crude is different in nature from most heavier crude oils. Among other things there is more methane in it, along with some other readily flammable chemicals (can't remember the names) that make it much more volatile than normal crude oil. I may easily be mistaken but I don't recall seeing mention of crude oil tank cars blowing up in prior years the way the current Brakken oil does. John Larkin

Today, crude oil (and diesel) are classed by the AAR as "combustible liquids", not "flamable". There is no AAR requirement to use buffer cars to separte combustible liquids from engines, occupied cabooses, or business cars. Individual railroads may have rules that are more restrictive, but crude is always a "combustible". I'm not sure what the AAR rules were pre-1961, but I doubt they were more restrictive concerning train & switching placement.

Sure, exactly what I said. It was the original comment which generalized about "crude oil" without qualifiers.

I've been told by someone that repairs
tank cars ( and other rolling stock) that the Batten crude is not only highly
volatile but very corrosive. Thankfully none of this was carried in steam era
cars.

I think we are missing the original question as to placement of tank cars in a train....there is no restriction on where a tank car can be placed...the restriction as to placement comes with the placards applied to the car....no placard it is just another car.....as info box cars with exposive placards had to have 15 cars between them and engines, cabins, etc.......Lar

I was replying to Tony specifically about crude oil (placard combustible) and placement in train. You are incorrect on the placement of cars placarded "explosives". Explosives can be in Group A, D, or E. Group D explosives (other than a loaded tank car) and all Group E explosives can be placed next to engines, etc...
