Microprocessor Radio Locomotive Control
HUBBELL
Hubbell 72 & 450 MHz Remote Control System for Locomotive Applications
The Hubbell Intelligent Radio Loco-
motive Systems features a micro-
computer with status
display and built-in di-
agnostics along with
our high speed, digi-
tal, biphase modula-
tion to provide reli-
able, efficient and
economical operation
of diesel-electric loco-
motives from a por-
table transmitter.
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.
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.
• 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.
• Cost Reduction — Operating crew
is reduced on each shift. Payback
is realized in just a few months.
• Better Visibility — Remote control
takes the operator out of the cab
providing him with improved visibil-
ity and total control from grade level.
• Simple Operation — Portable,
lightweight transmitter is easier to
operate than manual controls.
