The LHB-car , English LHB coaches are a coaches genus of the Indian Railways (IR), which from the 2000s, first in the high- speed trains will later be used in the other passenger trains and slow the older ICF-car replaces .
history
From 1993, IR initiated the procurement of new wagons, which can reach higher speeds on the existing routes compared to the existing ICF wagons. In 1995 it signed a contract with the German manufacturer LHB , under which the company, which was later taken over by Alstom , had to deliver 24 air-conditioned express train passenger cars. LHB also undertook to provide a technology transfer for the production of the cars in India.
The production facilities for the LHB cars are in the Rail Coach Factory (RCF) in Kapurthala, 400 km northwest of Delhi . By August 2020, 6,500 of the LHB wagons had been built. The production of the ICF wagons, the predecessor series, was stopped in January 2018. In July 2020, RCF completed 151 LHB wagons, which was the largest number of units produced in one calendar month since operations began.
The cars have been used on the rail network since 2000. Initially, they should only be used for the high-quality express trains of the train types Rajdhani Express , Shatabdi Express and Duronto Express . The imported wagons ran for a while in the Delhi- Lucknow -Shatabdi, where initially there were problems with broken windows, train separation and weak air conditioning, so that Alstom had to make improvements. From December 2003, the first cars manufactured by RCF operated in the Delhi-Mumbai Rajdhani. Later the railway decided to convert all passenger trains to LHB wagons, as these are lighter and safer than the ICF wagons.
technology
The car bodies are made of stainless steel , the partition walls in the interior are made of aluminum . With a length of 23.54 m, the box is more than two meters longer than that of the ICF wagons, which gives the LHB wagons a larger capacity. They have larger windows that give passengers a better view and improved soundproofing over the old cars. Two air conditioning systems built into the roof cool and heat the interior. A microprocessor control ensures that the toilets are only emptied when the car is traveling at least 30 km / h. As a result, the tracks in the station area should be less soiled. The cars are supported by air suspension on bogies that had been developed by FIAT SIG in Neuhausen am Rheinfall and derived from those of the Eurofima cars . The weight of the bogie is 6.3 t.
