Do trains have to have EOT devises when there are single or multiple locomotives pushing a train?
On the Pocahontas Division of the NS the pusher Engineer removes the e.o.t.d. and then replaces it sometimes when he’s finished pushing.Sometimes the car dept. does this when the train makes it to a yard,and when the pusher has cut away after “draping” the train over the hill,meaning it’s over boths sides of the hill.
Also on the Poca. a pusher is only allowed one six axle of pushing power on a time freight,and two on a coal train.And no hazard or shiftable loads are permitted on the rear next to the pusher unit.
Piggyback trains are not allowed to be pushed at anytime.[:)]

Here [in SE Kansas], Specifically, Parsons, on the UP; all UP Coal Trains running with a DPU do not use a EOT, due to placement of power unit on the rear. Union Pacific on the largest share of their uint trains here, uses a single unit in DPU. The BNSF Unit trains[Coal] on run through always seem to have two units[ 2 at head end and 2 at rear of train] in DPU function, also no EOT in use{maybe, this facilitates an ability to avoid having to turn the train for the return trip?} Philosophical operating differences, I would guess? UP’s Unit Grain trains sometimes will not use a DPU at the rear of the train, but will place three or four operating units at the head end, and EOT at rear of train. Not exactly sure of the reason for the differences in placement of power. Coal trains always seem to use DPU’s on UP Trains…
