Got stuck by a unit tank car train (not a TankTrain) on the BNSF (with NS power) the other day in Downers Grove.
I couldn't help but notice both the first and last cars bookending the train were covered hoppers. It stuck me that these might be "buffer cars" to protect the engine crew and the end of train.
Is this a way of doing things nowadays with unit tank car trains, the way BNSF does it or does it depend on the cargo?
Inquiring mind wants to know.
