2.5.2 Transmitter Line Applications

When it is desirable to transmit signals over dedicated line wire or buried cable to the track, a
Line to Receiver Coupler, 7A388 (See Section 3.3.3 and Figure 3-8), must be used to couple
the transmitter to the line and a Transmitter Line to Rail Coupler, 7A399-f (See Section 3.3.5
and Figure 3-11), must be used to couple the line to the rail (for application drawings see Figure
9-11 and Figure 9-12). Correct frequency information must be specified in the railroad's or
agency's written instructions and the couplers should be installed per those written instructions.
A typical application is when the distance from the transmitter to the rail is between 300 – 2000
ft. (91.4 – 609.6 m) (based on using 14AWG, increasing the diameter of the wire will
proportionally increase the potential distance from 2000 ft./609.6 m). See Section 7.2.3 for
further information regarding maximum distances for track wiring).

2.5.3 Receiver Line Applications

When the receiver is connected to the track via dedicated line wire or buried cable a pole-
mounted Receiver Line to Rail Coupler, 7A377-1-f (See Section 3.3.4.1 and Figure 3-9), or the
shelf-mounted Receiver Line to Rail Coupler, 7A377-2-f (See Section 3.3.4.4 and Figure 3-10)
is required to couple the track to the line. A Line to Receiver Coupler, 7A388 (See Section 3.3.3
and Figure 3-8) is used to couple the line to the receiver (see Figure 9-8, Figure 9-9, and Figure
9-11 for typical application drawings). Correct frequency information must be specified in the
railroad's or agency's written instructions and the couplers should be installed per those written
instructions. A typical application is when the distance from the receiver to the rail is between
300 – 2000 ft. (91.4 – 670.6 m) (based on using 14AWG, increasing the diameter of the wire will
proportionally increase the potential distance from 2000 ft./609.6 m).

2.5.4 Insulated Joint Bypass Couplers (Non-Electrified Rail Only)

WHEN GRADE CROSSING PREDICTOR (GCP) OR MOTION SENSOR
FREQUENCIES ARE ALSO BYPASSED AROUND INSULATED
JOINTS, ALONG WITH PSO FREQUENCIES, ALWAYS FOLLOW THE
INSTRUCTIONS GOVERNING THE GCE OR MOTION SENSOR
APPLICATION AND INSTALLATION.
The A62776 MS/GCE Termination Shunt Burial Kit is designed to protect
shunts while they are buried. For additional information, refer to Section
9, Auxiliary Equipment.
