RTR Technologies, Inc., an ISO 9001: 2000 equivalent, certified DBE / WBE, is a manufacturer of de-icing and corrosion prevention systems and related controls for the rail and mass transit industries worldwide. RTR designs and manufactures an extensive line of high-performance systems for:

  • Contact rail de-icing systems and controls
  • Guideway snow and ice melting systems and controls
  • Power rail snow and ice melting systems and controls
  • Switch point snow melting systems and controls
  • Door system heaters and controls
  • Passenger comfort heating systems and controls
  • High-performance electrical harnessing
  • Electro-mechanical / electronic trainline, HVAC and door operating controls
  • Overhead catenary contact wire de-icing systems and controls
  • "C3" climate corrosion controllers for temperature and condensation control


RTR’s line of contact rail heaters uses self-regulating and constant wattage heater technology (600VAC to 750VAC) to de-ice contact and running rails. RTR offers both traditional hard wire and radio frequency controls for our heating systems. Since 1980, more than 2 million feet of contact rail heaters has been installed worldwide preventing accumulation of ice and snow and reducing interruption of service.


Snow and ice build-up between the stock and switch rails can cause malfunction of the signaling system and increase the risk of damage and derailment. RTR’s switch rod and switch point heating systems help to eliminate service interruptions and equipment failure caused by compaction and compression of ice and snow in switches.


During cold weather, railroads may experience interruption of service due to frozen valves, pipes and other equipment. Utilizing proven self-regulating and constant wattage heating technologies combined with highly reliable optimized controls, RTR provides railroads and their suppliers with numerous long lifecycle valve heating systems (including air, drain and exhaust valve), pipe freeze protection systems, water tank heaters and coupler heaters.


RTR’s self-regulating and constant wattage threshold and door guide heaters keep thresholds, door guides and door pockets free of ice and snow build-up without the need for costly electro-mechanical controls. RTR’s heating technology keeps the surface temperature of the threshold well within a safe temperature zone for passengers, railroad personnel and equipment.


RTR is a recognized supplier of retrofit control and relay panels and systems. Utilizing existing space and car body wiring, RTR designs and engineers modular replacement systems to update obsolete equipment (including HVAC, Trainline and door operating systems). These systems increase mean time between failures, reliability and duty cycle.

RTR specializes in teaming with leading-edge firms to meet complex engineering challenges by ensuring their customers’ equipment operates in a safe, reliable and cost-effective manner while being virtually impervious to snow, ice, corrosion and temperature extremes.

RTR is an expert in devising cost-effective, turnkey solutions in order to ensure a substantial reduction in total installed costs as functions of:

  • Design / application compatibility
  • Purchase price
  • Ease of installation
  • Durability / reliability
  • Safety
  • Increased MTBF (Mean Time Between Failure)
  • Decreased MTTR (Mean Time To Repair)
  • Long service life
  • Low lifecycle cost

With an unwavering commitment to quality, RTR designs and manufactures zero defect, cost-effective products and systems which satisfy customer requirements. Technical support, training and on-time delivery complete RTR’s total dedication to customer satisfaction.
