Railway Rolling Stock

The railway industry is known for very extreme working conditions for electrical equipment, where vibration, dust, temperature, humidity variations and electric interference requires that all electrical components must work under very harsh conditions. With a heavy demand on reliability Mors Smitt railway components are manufactured and tested to offer long effective hours of work and low life-cycle costs.

Mors Smitt products are designed and compliant to the strictest railway directives, such as EN 50155 Electronic equipment used on rolling stock for railway applications, IEC 60571 Electronic equipment used on railway vehicles, and EN 50463 Energy measurement on board trains.

Filter

Relays

Mors Smitt widest relay range fit for all railway rolling stock applications. Continuous innovations and obtained “Silver” quality performance level of IRIS certification for single railway components.

Circuit Protection

Wide range of Mors Smitt railway hydraulic magnetic circuit breakers meet individual customer requirements and can handle challenging environmental conditions.

Engineered Solutions

Mors Smitt engineered control panels for any onboard challenge of space limitations or technical requirements for a new built or retro-fit. Size and quantities on demand.

Onboard Systems

Range of systems for vital onboard applications, such as Intelligent Circuit Protection (ICP), Train Protection and Warning (AWS/TPWS) and Automatic Power Control Systems.

Energy Measurement and Traction Control

Highly accurate high voltage and current measurements for energy calculation on board. Includes catenary detection and reference signal for traction synchronization. Easy integration on a new build or existing trains.

Hall Effect Sensors

Hall effect sensors offer maximum protection and ensure high accuracy of voltage and current measurements in railway traction or sub-station power equipment during power surges, overload or ground faults.

Protection Relays

Electrical relays for high voltage and high current protection in traction equipment as well as railway infrastructure. Used to detect catenary voltage, short circuit, overload or ground fault in traction power electronics or railway sub-stations.

Maintenance & Test Equipment

Comprehensive set of Mors Smitt maintenance and test equipment for in-service inspection, fault finding, and verification of relay conditions for optimal life-cycle costs of equipment.

Panel indicators (DISCONTINUED)

The signalling / infrastructure sector is served with systems that ensure factors as full signal integrity, automatic train protection, energy distribution and control. For many years, our Panel Indicators have been a reliable component in different systems.

Due to decline in demand and increasing production and distribution costs, we will discontinue this product line as of December 31, 2025.

Retrofit & Replacement Solutions

With an increasing demand to replace relays or accessories in installations, which have become obsolete, replacement solutions have to be form, fit and function compliant (FFF).

Vapor Relays & Contactors

Vapor relays and contactors have established a reputation for quality and reliability for critical applications in rail passenger cars and locomotive control and starting circuits.

British Rail relays

Mors Smitt relays include the full range of British Rail relays with AC & DC coils, instantaneous, gold contacts, safety critical, push to test relay button, timer/time delay, and flashing relays.
