3. INTRODUCTION ABOUT RDSO
 1853 – Railway was introduced in India.
 1903 – IRCA was set up.
 1930 – IRCA was changed to CSO.
 1952 – Due to increased demand of Rail transportation RTRC was set up.
 1957 – CSO and RTRC was integrated in a single Unit named as RDSO at
LUCKNOW under the control of Ministry of Railway

5. SIGNAL 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 ISO 9000. These include programmable
environmental (heat & humidity), dry heat, cold, mould growth, salt mist
spray, dust, rain chambers etc.
