Receiver Cabinet
By operating the
transmitter switches, a radio mes-
sage is sent to the locomotive
mounted receiver to control the di-
rection and speed of the locomo-
tive. Additional data bits are avail-
able to perform special auxiliary
functions such as sounding of horn,
application of brakes or control of
couplers.

Lo
i
Each radio control system operates
on a licensed frequency in the 72–
76 MHz or the 450–470 MHz
bands. The receiver is crystal con-
trolled. A synthesized 72–76 MHz
receiver is also available.

Benefits
• Easy to Maintain — Self diagnos-
tics identify problem areas via the
status display.
cseorRad
• Fast Response — High Speed data
rate offers fast, responsive operation.
• Frequency Conservation — Up to
four systems can share the same
radio frequency, which also saves
on spare parts requirements.
por
• Cost Reduction — Operating crew
is reduced on each shift. Payback
is realized in just a few months.
r
c
i
• Better Visibility — Remote control
takes the operator out of the cab
providing him with improved visibil-
ity and total control from grade level.

Pneumatic Cabinet
Sp e cifica t io n s
The pneumatics enclosure
is of NEMA 12 construc-
tion and houses the pneu-
matic controls for the re-
mote operation of the lo-
comotive. The locomotive
throttle, independent
brakes, and the train line
brakes are normally oper-
ated via binary pneumatic
valves for control of the air
pressure. Other functions
