Where the wires are carried through the floor or any partition, a
steel chute, lined with electrobestos, is used to protect the wires
against mechanical injury. It will be noted from the above that no
power wiring, switches, or fuses are placed in the car itself, all
such devices being outside in a special steel insulated compartment.
A novel feature in the construction of these cars is the motorman's
compartment and vestibule, which differs essentially from that used
heretofore, and the patents are owned by the Interborough Company. The
cab is located on the platform, so that no space within the car is
required; at the same time the entire platform space is available for
ingress and egress except that on the front platform of the first car,
on which the passengers would not be allowed in any case. The side of
the cab is formed by a door which can be placed in three positions.
When in its mid-position it encloses a part of the platform, so as to
furnish a cab for the motorman, but when swung parallel to the end
sills it encloses the end of the platform, and this would be its
position on the rear platform of the rear car. The third position is
when it is swung around to an arc of 180 degrees, when it can be
locked in position against the corner vestibule post enclosing the
master controller. This would be its position on all platforms except
on the front of the front car or the rear of the rear car of the
train.
The platforms themselves are not equipped with side gates, but with
doors arranged to slide into pockets in the side framing, thereby
giving up the entire platform to the passengers.
