Electrified Transit and Third Rail

Electrified transit and third rail systems are reliable and environmentally friendly mass transit solutions. Constructing these systems requires an extensive number of steel rails, caps, ramps, anchors, and other components. These products must be precisely fabricated from high-quality raw materials to ensure safety and longevity.

At Selco, our fabrication services support the longevity and operational efficiency of mass transit infrastructure. We create durable transit rail products for agencies like NY MTA, Amtrak, BART, and SEPTA. Our products sustain both over-running and under-running third rail systems, meeting all relevant specifications for North American transit projects. Some of the most common components we fabricate for electrified transit applications include:

Brackets Brackets
Cable Trays Cable Trays
Signal Platforms Signal Platforms
Protection Boards Protection Boards

Transit Rail Products

We offer a comprehensive range of transit rail products to support the needs of both heavy rail and light rail systems. Some of our most popular offerings include:

  • Copper connectors
  • Silver ball and knife disconnect switches
  • Substation equipment
  • Snowmelters
  • Signal distribution platforms
  • Relay rooms

In addition to these solutions, we also custom fabricate third rail brackets, protection boards, and anchor sets for agencies like Amtrak, PATH, and Metro-North. With over a century of manufacturing expertise, our solutions meet the demanding standards of modern transit authorities.

DC Traction Power Distribution

Many metro train systems run directly on DC power. Since converting from AC to DC results in significant energy loss, DC power systems are a more efficient and environmentally friendly transit solution. Direct current systems offer high torque at startup and accommodate precision speed control during operation, making them the ideal option for many transit applications.

Building a DC traction power distribution system requires a multitude of fabricated steel products. Selco Manufacturing has a long history of creating DC power distribution components for rail and industrial projects, with many of our electrical products listed by Underwriters Laboratories. As the shift toward renewable energy transportation and battery storage accelerates, our solutions support critical infrastructure modernization efforts.

Electrical Enclosures

An electrical enclosure is a special type of cabinet designed to protect electronic equipment. NEMA-rated enclosures signify the ability to withstand specific environmental conditions. These requirements, established by the National Electrical Manufacturers Association (NEMA), standardize enclosure manufacturing. With our proven solutions, you can be certain that your products will perform as required in their end-use environment.

Electrical enclosures from Selco safeguard America’s most critical infrastructure systems from environmental and operational hazards. These components provide reliable protection for sensitive equipment in bridges, substations, tunnels, and water treatment facilities. At Selco, we design and fabricate electrical enclosures across all NEMA ratings, including 4X and 6P.

Cable Trays and Fittings

Modern infrastructure projects require an extensive amount of cabling. Cable trays ensure that all wires are safely supported and protected. At Selco, we create durable cable management products that keep cables out of the way while still allowing easy access for maintenance. We fabricate an extensive range of design options, including:

  • Solid-bottom cable trays
  • Channel trays
  • Ladder trays
  • Ventilated trays

All of our cable tray designs are configured for fast and easy installation. Our solutions are fabricated from durable materials like stainless steel, Corten steel, and aluminum, which offer durability and grounding capabilities. Cable trays from Selco are used throughout high-voltage and third rail projects, as well as many industrial and commercial facilities.

Steel Security Bollards

Protecting people and property from road accidents is a critical requirement for government and commercial facilities alike. Steel security bollards provide the strength needed to withstand high levels of impact and protect structures from vehicular accidents. They also delineate pedestrian and vehicle areas.

At Selco, we manufacture many types of steel security bollards, including:

  • K-12 crash-resistant
  • Shallow mount
  • Rising
  • Fixed

Fire-Rated NEMA 4X Boxes

As a leader in fire-rated electrical enclosures, Selco was the first manufacturer in the world to offer FHIT-certified cable in-conduit solutions. Our fire-rated NEMA 4X boxes are UL certified and pass the two-hour fire-rated endurance test specified under UL 2196 and ASTM E119 standards. Our solutions are manufactured using grade 304 stainless steel and flame-rated silicone gaskets.

Every enclosure is water-tight, corrosion-resistant, and designed for use in critical infrastructure projects. In applications like major transit hubs, subway systems, and tunnels, our products provide reliable fire protection and endure harsh environmental exposure.
