Installing Head-End Power on a railroad passenger car would be a lot more difficult without Northwest Rail Electric's HEP Mounting Plates, Communication Receptacle Mounting Boxes, MU Receptacle Mounting Boxes.

HEP Mounting Plates

Northwest Rail Electric HEP Mounting Plates are designed to work with Clements HEP Connectors and comm/MU connectors.

HEP connector Mounting Plate

This is a photograph of Northwest Rail Electric part # HPMTGPLT. There isn't much sophistication or detailed features. This is what your shop crew needs to weld onto the end of the car ( in four places for full Amtrak HEP compatibility ) for the connectors that carry the head-end power from one passenger car to the other.

Northwest Rail Electric's HEP mounting plates are laser cut, so that it will always fit the connector mounting assembly. It would not be possible to fabricate your own HEP mounting plate as quickly or as cheaply as you can buy these from us, and it will save you a lot of headaches.

HEP Single Mounting Plate

This is a photograph of Northwest Rail Electric part # HPMTGPLTS. This is a HEP mounting plate that is designed for tourist railroad cars that do not need full head-end power capability. It could also be used to mount a HEP connector on the side of the car to receive yard power. For information on the various HEP train line configurations used in North America, please see our Basic HEP Information page.


Comm. / M.U. Receptacle Boxes

Communications and MU Mounting Box

Northwest Rail Electric part Double Comm/MU Box is a double-hole mounting box for installing both multiple-unit ( MU ) receptacles and communications ( Comm ) onto your passenger car. Communications lines are required for passenger cars operating in any Amtrak train, while operating on certain Amtrak routes requires both COMM and MU.

MU or Communication Mounting Box

Northwest Rail Electric part Single Comm/MU Box is a single-hole mounting box for installing either multiple-unit ( MU ) receptacles or communications ( Comm ) onto your passenger car. Communications lines are required for passenger cars operating in any Amtrak train, while operating on certain Amtrak routes requires both COMM and MU. MU would be required, for example, if installing a system on a passenger car that operates anywhere cab-control passenger cars would operate, or for operating on a system where a locomotive might operate on each end of the passenger car ( such as some locomotive testing cars do ).

In both cases:

Parts Required to convert a passenger car to HEP.

A brochure is available in the PDF format brochures area of our web site that also lists the parts required to convert a passenger car to head-end power.
