This guide explains the role of CLS Panels, their working principle, key features, railway applications and the factors to consider when selecting a railway electrical equipment manufacturer.
What Are Railway Electrical Products?
Railway electrical products are equipment and components used in railway power distribution, signalling, control and supporting electrical infrastructure.
These products help supply, control, distribute and protect electrical power for different railway applications.
Depending on the project, railway electrical equipment may include:
- CLS Panels for colour-light signalling supply
- Railway LT Panels
- AC Distribution Boards (ACDB)
- DC Distribution Boards (DCDB)
- Control and distribution panels
- Terminal boards and junction boxes
- AC/DC fuse boxes

The exact equipment required depends on the railway application, approved drawings, technical specifications and project requirements.
What Is a CLS Panel in Railway Signalling?
A CLS Panel, or Colour Light Signalling Control and Distribution Panel, is an electrical panel used to provide and distribute power for railway colour-light signalling installations.
ESPL’s CLS Panel product information refers to RDSO Specifications TI/SPC/PSI/0020 and TI/SPC/PSI/0025. The latter covers the design, manufacture, testing and supply of a 240V, 50Hz AC power supply control and distribution panel for colour-light signalling installations in a 25kV AC traction system.
The panel’s source-changeover arrangement is intended to transfer the supply from the main source to an available standby source when the main supply fails, and back to the main source when it is restored, according to the specified configuration.
Why Is a CLS Panel Important?
Railway signalling installations require a dependable power supply for their electrical equipment.
A properly specified CLS Panel can help provide:
- Controlled distribution of the incoming electrical supply
- Automatic changeover between designated power sources
- Protection through suitable electrical devices
- Convenient monitoring of panel operating conditions
- Organised control of incoming and outgoing circuits
- A structured arrangement for railway signalling power distribution
The actual functions and configuration depend on the panel design and the applicable project specification.
How Does a Railway CLS Panel Work?
A CLS Panel receives electrical power from the designated incoming supply sources and distributes it to the required signalling circuits.
1. Incoming Power Supply
The panel receives power from the designated main source and, where provided, one or more standby sources.
2. Source Monitoring
The configured control arrangement monitors the availability of the incoming supply sources.
3. Automatic Changeover
If the main source fails, the changeover arrangement transfers the supply to an available standby source according to the approved design.
4. Electrical Distribution
The panel distributes the supply through its designated outgoing circuits to the connected equipment.
5. Protection and Indication
Suitable protective devices and panel indications help support circuit protection and operating-status monitoring.
6. Return to the Main Supply
When the main supply is restored, the system can return to the main source according to its configured changeover logic.
The precise operating sequence, number of incoming sources and outgoing circuit arrangement should be verified against the approved panel drawings and technical specifications.
Key Technical Requirements for Railway CLS Panels
When purchasing a CLS Panel, it is important to review the applicable RDSO specification, approved drawings and project requirements.
