Kapurthala, August 8

The Rail Coach Factory (RCF), Kapurthala, is working to reduce the weight of Linke Hofmann Busch (LHB) coaches, which will make them more efficient, help in saving energy and increase the speed of trains.

An LHB coach weighs around 46 tonne. It is one of the lightest coaches running in trains across the world.

Several design improvements have been made to the LHB coach shell, furnishings and electrical fittings to reduce weight. These improvements have made AC first class, AC-2 tier, AC-3 tier, sleeper and general coaches lighter by 7 quintal to 1.5 tonne.

The RCF said, "By bringing in changes in seats and berths, reduction in weight of 3 quintal, 6 quintal and 6.7 quintal will be achieved in AC first class, AC-2 tier and AC-3 tier coaches, respectively. Three quintal weight will be reduced by changing material of the AC unit. Replacing partition frame of the sleeper and general coaches with light honeycomb structures will result in substantial reduction of weight in the coaches. A provision has been made to reduce weight through design and structural changes in bio-tanks, transformers and switchboard cabinets, among others."

By adequate weight reduction, haulage cost will be reduced, which in turn, will save energy. The number of coaches per train can also be increased.

With the Indian Railways aiming to increase the speed of trains, these light weight LHB coaches will contribute to faster train travel.
