New pit line work commences at Mangaluru Central Railway station

As part of development of Mangaluru Central Railway Station, Palakkad division of Southern Railway has taken up the construction of a new pit line capable of holding 24 coaches at the coaching yard. The new pit line is constructed in lieu of the existing 18 coach pit line. This will also facilitate the construction of new platforms four and five to go with the existing three and also enable the railway station to handle more trains.

Pit lines are the main infrastructure required for conducting primary maintenance of coaches of both express and passenger trains. The pit line will have facilities for day/night inspection, coach cleaning, coach charging, watering and other allied maintenance works. The catwalks on the both sides of the pit line helps to easily get into the coaches, which makes the maintenance and cleaning work easy, maintain division officials.

Pitline Under Construction At Mangaluru Central Rly Station

After every scheduled trip, under gear examination, checking of braking system, electrical maintenance, cleaning, washing both exterior and interior, and checking the amenity fittings, watering of the coaches is done at the pit lines. After this, coaches are being given fit for 96 hours (4 days) run from the carriage depot.  Draining out the water tanks and maintenance of bio toilets are also carried out at the pit line in regular intervals. 

All the maintenance activities are according to the guidelines given in the coach maintenance manual issued by the railway board. In addition to the trip attentions, monthly schedules and tri-monthly schedules are also carried out in the pit lines. Other than trip attentions and scheduled maintenance, after nine months of service, coaches are sent for intermediate overhauling. After 18 months, periodic over hauling of coaches is carried out.

The latter overhauling schedule is undertaken at nominated railway workshops. The new pit line at Mangaluru Central is being constructed at the eastern side of the coaching yard. The 596 metre length pit will have the capacity to handle a train rake of 24 LHB coaches or 26 ICF make coaches. The estimated cost of the project is ₹6.76 crore.  Demolition of the existing 18 coach pit line and skewing of the track is part of the project.

A rake requires an average of 8 hours for the maintenance at the pit line.  The new 24 coach pit line being constructed in lieu of the existing 18 coach pit line will be suitable for maintenance of all coaching rakes.
