On-Board and Rolling Stock

For operation in mobile environments, electronic systems require a physical construction capable of withstanding extreme conditions in harsh environments. nVent SCHROFF cabinets, cases and subracks are therefore designed to protect the electronics they house with high levels of mechanical stability and resistance to shock and vibration, according to EN 50155, EN 61373, EN 45545, CENELEC and AREMA.

Upgrading, adding new electronics & Maximizing limited space in on-board railway applications.

The rail industry is well established and, as a result, there is legacy infrastructure in place along with a need to upgrade existing rolling stock with new technology to enable predictive maintenance, safety initiatives, and next generation 4G-LTE and 5G communications to enhance customer experience and enable better signaling capabilities.

Modernizing aging equipment for rolling stock presents unique challenges such as

  • Installing more electronics in onboard locations where space is at a premium
  • Maximizing space while creating passenger and operator friendly interiors
  • Adding new electronic systems also introduces a higher complexity electromagnetically
