Railway Board Secretariat Service
The Railway Board Secretariat Service (RBSS) (हिंदी : रेलवे बोर्ड सचिवालय सेवा) is a central civil service with induction at Group 'B' stage in the Secretariat of the Ministry of Railways (Railway Board) of the Union Government of India. Origin 
Railway Board Secretariat Service was constituted with effect from 1.12.1954 under the Railway Board Secretariat (Re-organisation and reinforcement) Scheme. The model followed in setting up the service was the Central Secretariat Service which had been re-organised under the Central Secretariat (Re-organisation and re-inforcement) Scheme, framed by the Ministry of Home Affairs, with a view to strengthen the secretariat structure of other Ministries of Government of India.
