    Specifically designed for mouting under railway passenger cars, the Stadco RailgenTM diesel generators are a very good solution for small package auxiliary power under the floor of railway passenger cars. Available in sizes up to 160kw continuous rating, these generator sets may be used to provide HEP power to an entire train depending on the load characteristics of the cars.

    While the units are designed so that high-frequency maintenance items are available through the doors facing the outside, a roll-out service track is available to ease servicing of the rest of the generator set:

    Note also that the service track end columns also have a height adjustment on them, so that the roll out track may be used with a variety of elevations of track-side platforms or other structures.

    Stadco Generator under a Metroliner Connected to a Northwest Rail Electric Generator Control a Stadco generator mounted under a railway passenger car is able to provide automatic backup power so that if the HEP system fails or is disconnected, the generator starts and provides power to the car automatically.

    Stadco RailgenTM series generators have a compact design, and as stated above are designed specifically to serve as auxiliary power units on railway passenger cars. Cars equipped with Stadco generators under them are still able to meet even the most restrictive undercar clearance requirements in North America. Note the Stadco diesel generator (center of photo) used as an auxiliary power unit on the metroliner car shown at right.

    There are a number of accessories available for Stadco under-car generator sets, in addition to the roll-out service rails shown in the above photo. Standard packages are 12 wire 3 phase 240 / 480 volts, but other outputs available include 208 volt three phase. Several unique auxiliary power units for a specific Northwest Rail Electric customer with unusual needs involved producing a generator with simultaneous 208 and 480 volt output. Various other custom options are available. An extended run package is available for many generator sets that extends the operating time between oil changes.

    For the most up to date information on Stadco Generators, models available, various features of specific models, and exact dimensions please see the Stadco Generators web site, and look in the "Railgen" section.

    Our web site only features some basic information on these generator sets, for which we build control systems and for which we are able to act as distributors.


    A full silencing enclosure, multi-layer sound insulation, critical grade muffler, and specially tuned rubber mounts makes these sets extremely quiet and vibration free, while adding the optional secondary vibration isolation package makes them even more quiet.

    Control Packages

    Several Control System Packages are available from Northwest Rail Electric. Please inquire about our generator controls and automatic generator starting packages to provide automatic starting and operation of your Stadco generator if extermal power sources fail (HEP or yard). These packages are our NW-GC500 models.

    Our NW-GC155 series of generator controls provide simple power car control and are also compatible with Stadco RailgenTM undercar generators, but due to the differences in the control logic they do not provide for automatic power upon HEP failure.

    Northwest Rail Electric Generator Controls are specifically designed for Stadco Generators and using our control systems with a Stadco generator is compatible with the Stadco warranty system.
