OPERATING EQUIPMENT
Equipment such as the No. 592A Crossing Gate and the No. 761 Auto-
matic Semaphore are operated by the
No.
697 Pressure type track trip. This
trip can also be used to BLOW WHISTLES, CONTROL BLOCK SIGNALS,
OPERATE TRACK SWITCHES AUTOMATICALLY, or build a controlled
block system in your layout. I t can also be used to actuate lights and circuits.
This track trip can be adjusted to be operated by the Locomotive only or
by the entire train.
I t has no electrical connection to the track and is wired direct to the
power source and to the accessory it is to operate, then the weight of the
passing train closes the circuit just as if
you were to push a button on a con-
trol box, so in the case of a whistle or crossing gate where you would want the
entire train to keep the circuit closed the trip would be adjusted so that the
lightest car would close the circuit. In the case of a semaphore it would. be
adjusted so only the locomotive would actuate the trip and the following
cars would not affect it.
The trip can be attached to any section of track and T H E TRACK
ON EACH SIDE OF T H E T R I P SHOULD NOT BE FASTENED DOWN
SOLID FOR SEVERAL SECTIONS as the track must be free
to move up
and down to allow the contact to make and break.
