Carrying both acid and lye? Does having both on the same train make things more or less dangerous (mixing the two together will produce a very powerful exothermic reaction, but the by-products of that reaction will be sodium sulfate and water--not nearly as nasty as either NaOH or H2SO4).

I'm puzzled, though--wouldn't uncoupling cars on a moving train cause all the brakes along the entire train to get automatically thrown pretty quickly? Or did whoever uncoupled the cars cap the brake lines to prevent that from happening?

You're more informed than me.

I don't know.

The way I read it they were turning the manual brakes on the car (the big wheel) that sets individual brakes.
