Overview
SIST-TP CLC/TR 50452:2007 offers practical guidelines for the application of radio remote control systems in traction vehicles used for freight traffic, particularly in multiple traction (multitraction) operations. Developed by the Slovenian Institute for Standardization (SIST) and based on the European Standard EN 50239, this technical report identifies additional requirements and considerations for safely implementing radio-based controls in scenarios where two or more traction vehicles are deployed together. The primary objective is to enhance operational safety, efficiency, and interoperability in railway freight transport.
Key Topics
- Multitraction Operation: Guidance on the remote control of several traction vehicles operating together in a single train consist.
- Radio Remote Control: Requirements and best practices for system design, deployment, and management when using radio links for train control.
- Communication Protocols: Recommendations for the allocation of addresses, radio frequencies, and the prevention of signal interference among multiple trains.
- Risk Analysis: Identification of safety-critical functions and risk mitigation strategies for multitraction, particularly in cases of signal loss, braking coordination, and unintended train separation.
- Track Infrastructure Considerations: Advice on adapting radio remote control systems to different track layouts and regulatory environments.
- Application Examples: Illustration of typical multitraction configurations, including segmented and unsegmented braking systems, varied control locations (onboard, trailer, or outside the train), and methods for coordinating power and braking commands.
Applications
SIST-TP CLC/TR 50452:2007 is critical in scenarios where increased hauling capacity or flexibility is required, such as:
- Heavy Freight Operations: Enabling seamless integration and control of multiple locomotives to transport long and heavy freight trains efficiently.
- Interoperable Rail Networks: Supporting radio-based control in networks where wagons or sections of trains lack communication cabling, necessitating wireless communication for safety and efficiency.
- Complex Train Consists: Facilitating operation where leading traction vehicles (LTVs) and guided traction vehicles (GTVs) must be coordinated via radio link, with attention to address management and signal integrity.
- Challenging Topography: Offering solutions for safe radio command and control in tunnels, long-distance lines, and diverse national infrastructures.
Related Standards
This technical report works in conjunction with several key railway and telecontrol standards to ensure interoperability, safety, and compliance:
- EN 50239: European standard specifying requirements for radio remote control systems in railway applications, forming the foundation for this report.
- EN 50159-1 / EN 50159-2: Standards outlining requirements for closed and open transmission systems used in railway control and protection.
- IEC 33.200: Addressing telecontrol and telemetering systems.
- IEC 45.060.10: Related to tractive stock and railway vehicle standards.
Practical Value
Adopting the guidelines in SIST-TP CLC/TR 50452:2007 delivers strong practical benefits:
- Safety Assurance: Clear procedures for risk analysis and mitigation in radio remote control, reducing the risks of miscommunication, uncoordinated braking, or unintended train separation.
- Operational Flexibility: Supports both permanent and ad-hoc multitraction configurations, promoting adaptable freight solutions across various operational requirements.
- Cross-Border Compatibility: Assists rail operators in aligning with European best practices, supporting interoperability, and regulatory compliance in international freight corridors.
- Efficient Resource Utilization: Maximizes locomotive use in freight operations, allowing operators to efficiently combine or separate train consists as needed.
By following SIST-TP CLC/TR 50452:2007, railway operators and system integrators can design, implement, and maintain reliable radio remote control solutions, enhancing freight traffic operations and standardizing safety practices across rail networks.

The purpose of this Technical Report is to serve as a guideline for the application of radio remote
control system of traction vehicles for multitraction operation.
The European Standard EN 50239 is applicable for the radio remote control system of traction
vehicles for freight traffic. This standard sets out 14 application examples. It does not include an
example of multitraction operation; it only includes an example whereby a traction vehicle is controlled
by an appropriate driving trailer in a train consist (example 13 of EN 50239).
This Technical Report is based on EN 50239 and provides an indication of the additional requirements
relevant for the multitraction application.
1 General
Multitraction is used whenever
– the tractive effort of the traction vehicle is not sufficient for the particular operational application,
– different independent trains are linked together to form a longer train consist.
In a train consist with more than one traction vehicle, one of the traction vehicles is always the Leading
Traction Vehicle (LTV). The other traction vehicles contained in the overall train consist are controlled
and monitored by the LTV. This arrangement means that communication between the different traction
vehicles is necessary.
Communication can be achieved by means of a cable link or a radio link. A radio link is for example
necessary whenever there are wagons between the traction vehicles and whenever these wagons do
not have any communication cables with appropriate infrastructure.
Commands are generally sent by the operating personnel only to the LTV.
If there are wagons between the traction vehicles, the effect of longitudinal dynamic effort and braking
behaviour must be taken into consideration during r
