SIGNAL TESTING LABORATORY

1. AN OVERVIEW

RDSO, an ISO:9001 certified organisation, is the sole R&D organisation of

Indian Railways and performs the following important functions:-

Adoption, absorption and development of new technologies for use on Indian

Railways.

Development of new and improved designs.

Development of standards of materials and products specially needed by

Indian Railways.

Technical investigation, statutory clearances, testing and providing

consultancy services.

Inspection of rolling stock, locomotive, signalling and telecommunication

equipments, track components etc. for ensuring quality.

Quality audit of Railway workshops & production units.

RDSO has a number of laboratories, which are well equipped with research and

testing facilities for development, testing, and design evaluation of various railway

related equipments and materials.

Signal Testing Laboratory are fully equipped for development, testing and

investigations of most of the signalling equipments.

2. SIGNAL TESTING LABORATORY

Signal Testing Laboratory undertake testing of all types of signalling equipments

involving safety such as Signalling Relays, Block Instruments, Power Supply

Equipments, Point Machines, Signalling Cables, Electromechanical Signalling

Equipments/Components, Modern Signaling equipments, etc.

There is an exclusive section for environmental testing equipped with range of

climatic test facilities as per IS: 9000. These include programmable environmental (heat

& humidity), dry heat, cold, mould growth, salt mist spray, dust, rain chambers etc.
