5. 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

13. ST Central Workshop
1. Most of the work is done manually
2. Manual work results in lower accuracy and
low standard manufacturing
3. Workforce is not motivated.
4. Not enough investments are done in the
Research and Development activities
5. Absence of automation leads workers to
work for long hours hence they are fatigued
and don’t work up to the requirements.
PROBLEMS IDENTIFICATION

14. 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.
