Default Maintenance of Buses by various STUs

Some of the leading STUs have tens and thousands of buses running round the clock both on inter city and city routes. These buses need regular maintenance and these large organizations have large facilities to keep these vehicles running on the roads. Some requirements are outsourced such as coach building while some STUs build them in their own regional workshops. The mechanical upkeep of these buses are done both in depot and in workshops. Some of the buses in the fleet need specialized care such as the Volvos which are maintained by Volvo personnel deployed in depots itself as told by a BMTC staff. Some information collated from various STU websites are as follows. Any more information and pictures of workshops, buses under maintenance, depots, maintenance schedules are most welcome.


APSRTC follows two tier maintenance i.e. preventive maintenance of buses at depots and major repairs/ overhauls at workshops. To serve this purpose Corporation has constructed 7 retreading shops and 7 work shops. The Bus Body Building Unit in Hyderabad builds more than 600 bus bodies every year.
Modern and updated technologies have also been introduced. To provide thorough cleaning in minimum possible time, 28 Automatic Washing machines were installed at major bus stations and district head quarters depots at a cost of Rs. 28 millions. Each machine washes about 250 buses a day effectively


Every month all the BMTC buses are subjected to smoke check. The depots are provided with computerized emission testing machines. Emission norms ensured.
Preventive and periodical maintenance are being carried out as per the recommendation of the vehicle manufacturers and the schedule is as follows.
  • Daily maintenance (Every day)
  • Alternate day maintenance (Once in two days)
  • Ten day maintenance (Once in 10 days)
  • Docking-I, for every 20000 kms of operations.
  • Docking-II, for every 40000 kms of operations.
  • Docking-III, for every 60000 kms of operations.
  • Docking-IV, for every 80000 kms of operations.
The Corporation has provided four Mobile Workshops, which attends the en-route breakdowns immediately after receiving the message.

Though these details are given in their websites, the only thing common between them is they follow Breakdown maintenance. Most of them do not have a comprehensive preventive maintenance that's actually followed!

I find APSRTC Employees love their vehicles more than the others. Today I was following an AIRAVATH B7R and a GARUDA B7R, the GARUDA looked almost new. At the Satellite Bus Station in Kasturi Nagar, I found a VOLVO, parked neatly with the air-vents on the roof open to let out bad odour as the Bus rested

Parisar compared the performance of PMPML with bus service providers in five other Indian cities; BEST (Mumbai); MTC (Chennai); BMTC (Bangalore) and DTC (Delhi). In a previous study titled PMPML Report card, Parisar had quantified the performance of PMPML, which showed how PMPML scored low on all counts. The current study concludes that PMPML also performs considerably worse than other bus systems in Indian cities.

Default Re: Maintenance of Buses by various STUs

The above data looks very fishy especially comparing Breakdown rate of 0.0 (or negligible ) for MTC. Knowing MTC, the break down rate is definitely not this level. But one aspect I agree is that fleet age is younger which might contribute to lesser breakdowns as it has a policy of condemning buses even which are less than 5 years old.

PMPML surely fails in many areas apart from the ones mentioned below

Drivers and conductors have laid back attitude
There is no change carried , they ask for change from you all the time.

From the very brief time that i travelled, i noticed buses with missing floor panels, torn engine cover ,hanging body parts, non functional lights.

Default UPSRTC bus journey a test of endurance

This is the condition of buses run by UPSRTC. No wonder there are not many takers for such as commute which is so uncomfortable and filthy.

With the exception of just a few STCs most of the other state corporations are in a state of rot. Read on-
