In order to maintain its tracks in impeccable working order and to keep high levels of safety standards, Indian Railway is procuring and using latest machines and technologies available in the world. In this connection Northern Railway has inducted a Dynamic Tamping Express Machine for Broad Gauge Tracks.
This machines has been manufactured in India under MAKE IN INDIA initiative with imported components and is the first of a series of 42 machines that are going to be in service over Indian Railways.
Sh. M.K. Gupta, Member Engineering, Railway Board recently inducted the Machine on the tracks of Northern Railways.
When a train moves over a set of parallel rails, it generates enormous forces. More the speed more is the pressure exerted on the tracks. The entire track consisting of rails, sleepers and ballast is fairly elastic system that deforms and returns to its original position after the train has passed over it. But over time and repeated use the track progressively moves, causing deviations from the desired vertical and horizontal alignment.
For smooth and incident free running of trains, track maintenance has to be done at regular intervals – this includes leveling, lifting, lining and tamping, this ensures the ideal geometry of the track.
Tamping is the process of squeezing and uniformly re-arranging the ballast (rock pebbles) under the sleeper to keep the track in position and provide it with a homogenous ballast bed. The new 09-3X ‘Dynamic Tamping Express’ is a self propelled, bidirectional single unit high output tamping and stabilizing machine.
The machine has the advantage of an integrated stabilisation trailer. This eliminates the need for a separate stabilisation machine which reduces operating costs and track possession.
The machine is also equipped with the latest measuring and recording equipment. This means measurement of all necessary track parameters after tamping without an additional measuring run, which additionally reduces track possession time and costs.
