Development of Local vendor and tool for Rolling

Stock Spare.

The Rolling Stock Department has addressed challenges associated with Original

Equipment Manufacturer dependency and maintenance. Recognising the high cost

and long lead times for OEM-supplied train dampers, the department successfully
identified and validated indigenous suppliers as an alternate, capable of meeting

stringent compatibility, safety, and performance standards. Rigorous testing of the
newly developed dampers over a month demonstrated satisfactory performance,

paving the way for reduced reliance on the OEM, significant cost savings, and shorter
procurement timelines.

RST Department has also focused on the local manufacturing of non-critical train

spares. Collaborating with domestic manufacturers has led to the successful
indigenisation of key components like the Saloon Door End Stopper and the Gearbox

Composite Gasket, previously sourced exclusively from the OEM. This shift has
eliminated prolonged lead times and high costs associated with foreign procurement

while maintaining stringent quality and performance standards. Additionally, to address
frequent train damper failures and the lack of specialised tools for their dismantling,

the RST Department ingeniously designed and developed an in-house special tool.

This innovation enables thorough failure investigations, component replacements, and
overhauls without dependence on external suppliers, resulting in reduced maintenance
costs, improved repair efficiency, and minimised train downtime.
