A Modern Approach to Protecting Wayside Railroad Equipment from Lightning Damage

Tuesday, March 25, 2014
4:00 – 4:45 p.m.

The need to protect signal, power and data lines of the railroad infrastructure from the effects of lightning strikes is an ongoing issue. Traditionally, railway signal and power line protection against voltage and current surges resulting from lightning strikes has been provided through the use of spark gap-based surge protective devices incorporated within the railway bungalow structure.

Congress set a mandate for the implementation of Positive Train Control (PTC) as part of the Railway Safety Enhancement Act of 2008. This mandate has served as the driving force for the rail industry’s upgrade of its electronic control infrastructure. This mandate has, in turn, created the need for an upgrade in SPD design within the railway bungalow structure. Design requirements for SPDs to address the upgraded PTC system include faster turn-on times, lower let-through voltage levels, an upgraded mechanical design, hot-swappability, and a remote-sensing capability.

During this session, discussion will be held on:

  • The current state of railway signal line protection methods,
  • Proposed SPD design changes to address PTC operational requirement upgrades,
  • The remaining challenges to minimize lightning strike damage within the bungalow structure.
