Railway Power Solutions

 

We have helped Municipal Rail systems to extend car life for many years by replacing old technology with the newest and most advanced technology available. We have also helped save millions of dollars for these municipalities by:

  • Lowering installation time by insuring the product is form-fit-function identical to the equipment being replaced and is usually lighter than the equipment being replaced.
  • Lowering operating costs our replacements are more efficient, run cooler and require less power than the equipment being replaced.
  • Lowering repair costs our MTBFs are longer and MTTR are shorter than the equipment being replaced. In addition, our designs are usually more efficient and run cooler than the equipment being replaced.

We have supplied products to many Municipal Rail systems including New York City Transit Authority, MARTA, MBTA, BART, Metro North, LIRR and others. In addition, we have worked with several new car manufacturers.
