Dedicated "buffer cars" are only used on unit trains carrying hazmat because otherwise they would have to keeping looking for buffer cars. ALL trains are required to comply with hazardous material placement rules, they have buffer cars but they aren't dedicated cars, just cars in the train that can be used for cover..

Its not an "agreement", its the CFR hazmat placement rules.

The regulations have changed significantly since 1979, so if you are modeling after the 1980's you will need a more recent version of the rules.

According to what I read and was told by a retired CSX and NS conductor the FRA wanted 3 buffers behind the engines and two buffers on the end of the train. The railroads and FRA came to a agreement one buffer would be ok..
