First Class motor 8AM is one of the group of original First Class motors that retained their classification to enable an M(2nd Cl.) + AM(1st Cl.) pair to take E trains out to the edge of the suburban electrified Network - thereby allowing both classes of passengers to be catered for. The larger compartments of the 1st class originating car are shown by the broader panels between compartments compared to the 2nd class motor - see:
As with my other swingdoors, the model is scratchbuilt, primary components being: My casts for cab front, sides, van, cab roof, under-chassis detail and last compartment, modified G&E sides and roof, SEM bogie sides, Tomix cross-arm pantograph, and a scale wood chassis.
