Not all heroes wear capes; some just know how to source the railroad components that keep trains moving. When a train goes down because of a failed circuit or blown fuse, finding a replacement isn’t always simple.

Many of the original parts used in legacy rail systems haven’t been manufactured in years.

That’s where Summit Electronics comes in. We are an electronics parts supplier specializing in obsolete and hard-to-find railroad components used in trains, subways, trolleys, and other rail vehicles.

Call Us at (800) 226-6960 for the electronic railroad components you need!

Who Needs Obsolete Railroad Components?

Transit systems aren’t designed to be replaced every five years. Many last for decades. But the electronic parts for trains used in those railway systems often become unavailable long before the equipment they’re built into is retired.

We serve:

  • Intelligent Transportation Systems (ITS) integrators
  • Public transit maintenance departments
  • Tolling and traffic management contractors
  • Transportation infrastructure contractors

Our railway and other transportation clients need reliability and long-term support. That’s why they turn to our electronic parts store when sourcing discontinued electronics for subways and rail systems.

Types of Railroad Components We Supply

We specialize in obsolete and discontinued train electronic components that are hard to find through standard channels. Our inventory and sourcing network cover the essentials that keep rail systems operational:

sum

  • Diodes – used in rectifiers, voltage regulation, and protection circuits
  • Relays – for switching, control logic, and signal routing
  • Switches – including toggle, pushbutton, and rotary types
  • Fuses – critical for overload protection
  • Connectors – for secure, high-reliability electrical connections
  • Circuits – including integrated circuits and control boards
  • MOSFETs – for power switching and motor control applications

Why Sourcing Obsolete Railroad Components Is a Challenge

The biggest risk to older systems isn’t wear and tear. It’s finding the parts to keep them running. Many electronic parts for trains were only manufactured in short production runs or have been discontinued for years.

Problems we solve every day:

checkox Components go end-of-life, but systems are still in service

checkox Manufacturers stop supporting older product lines

checkox Delays in sourcing create operational risks

checkox Finding substitutes that meet specs takes time and expertise

Summit Electronics helps fill these gaps. We specialize in tracking down electronic components that most distributors can’t supply.
