MPRX
TransCore Proprietary 3–3
Required Materials
• Torque wrench (in/lb. range)
• Bolts and nuts (#10-24 NC threaded studs and nuts)
• Aluminum pop rivets
• Pop rivet gun
Mounting Surface
The mounting surface must be metal, vertical, and smooth within the area of the tag. If the
mounting area does not meet this requirement, you must use a metal mounting bracket.
If the mounting surface is irregular or non-metal (e.g., fiberglass), the tag must be
attached to a metal bracket to provide an electrical reflector for the tag. Use a 1/8-inch
(0.32-cm) or thicker smooth metal bracket that is the same size or larger than the tag.
The mounting bracket and tag must be in contact with each other to avoid interference
with transmission of radio waves.
Tag Positioning
Each piece of equipment has a specific area or tag placement window for optimum tag
placement. Tag positioning in the tag placement window is based on the center of the tag
in reference to window physical parameters.
The tag placement window is on opposite ends and opposite sides of the equipment.
The front and rear ends of the equipment are referred to as the “A” end and “B” end.
The “B” end represents the hand brake end and the “A” end represents the opposite
end looking forward. To determine left and right sides, stand at the “B” end and look
toward the front end of the equipment.
Refer to the appropriate section for tag placement window location on rail cars and
locomotive devices. Where possible, tags should be mounted in locations that minimize
the likelihood of damage from equipment such as forklifts, cranes, and other hazards.
Mount the tag on a plane perpendicular to the rail (back of the tag against the
equipment) with the long edge of the tag horizontal to the rail.
There is a clear zone surrounding the tag and toward the wayside that allows for
unobstructed data transmission. This zone must not be obstructed by any metallic
objects or protrusions.
