History

● The Maharashtra State Road Transport Corporation was established by State Government of

Maharashtra as per the provision in Section 3 RTC Act 1950.

● The M.S.R.T.C is operating its services by the approved scheme of road transport published

video Notification MVA 3173/30303-XIIA dated 29.11.1973 in the official gazette.

● The first bus was flagged off from the Pune to Ahmednagar in 1948.

● In the early 1950s, two luxury coaches were also introduced with Morris Commercial Chassis.

● There were 10 makes of buses in used during 1950 - Chevrolet, Fort, Bedford, Sedan,

Studebaker, Morris Commercial, Albion, Leyland, Commer and Fiat.

● After Asia buses Volvo Luxury Buses where introduced.

Raw Materials

The raw materials used in the body building of buses comprise mainly of MILD STEEL for CROSS BAR CHANNEL and other weight bearing parts of the bus. The rest of the body is made up of SHEET ALUMINIUM.

Pros:- ● Light Metal ● Corrosion Free ● Fast Recovery ● Inside Safety

ST Central Workshop

1. Most of the work is done manually2. Manual work results in lower accuracy and low standard manufacturing3. Workforce is not motivated.4. Not enough investments are done in the Research and Development activities5. Absence of automation leads workers to work for long hours hence they are fatigued and don’t work up to the requirements.

PROBLEMS IDENTIFICATION

ST Central Workshop

Suggestion

1. Manual work is a big hindrance in the quality production. Automated machines and tools should be inducted because their combination will increase accuracy.

2. Safety of workers should be increased.3. Proper research should go into the alternatives for currently used raw materials

and designs with the changing demands.4. Superior quality paints and other alternatives will make even better buses which will be good for the organisation in the long run.
