Linke Hofmann Busch (LHB) coach is a passenger coach of Indian Railways that is developed by Linke-Hofmann-Busch of Germany[1][2] and produced by rail coach manufacturing units at Kapurthala, Chennai and Raebareli.[3][4] They have been used since 2000 on the 5 ft 6 in (1,676 mm) broad gauge[5] network of Indian railways. Initially, 24 air conditioned coaches were imported from Germany for use in the Shatabdi Expresses, following which, the Rail Coach Factory started manufacturing after technology transfer.[6] IR declared that all ICF coaches will be replaced by LHB coaches to provide more safety and comfort. The last ICF Coach was flagged off on the 19th of January, 2018, making way for LHB Coaches to be used for all new coaches to be introduced by Indian Railways in the future.[7]

History

During 1993–94, Indian Railways decided to look for a passenger coach design which would be lighter and capable of higher speeds compared to their existing rakes. The main features of the Railways' specification were high speed light weight coaches to run on the present infrastructure of the Indian Railways, i.e. the railway, track and environmental conditions in India at an operating speed of 160 km/h (99 mph).[5][8] It was decided by the Railways that the design would first be tried in the Rail Coach Factory in Kapurthala (RCF), and upon successful completion of this trial, it would be tried in the Integral Coach Factory in Perambur.[6]

In 1995, after a global selection process, Alstom-LHB received the order from Indian Railways to design and develop a new passenger coach under a transfer of technology agreement.[8] As part of the order, Alstom-LHB had to execute two contracts, one for the supply of "Light Weight High Speed Coaches for Broad Gauge"[5] which includes the development, design and manufacture of 19 AC 2nd Class Chair Cars, 2 AC Executive Class Chair Cars and 3 Generator-cum-Brake vans[9] and the other contract for the "Technology Transfer" which includes the transfer of technology for design and manufacturing, the training of Indian Railways personnel in the premises of the manufacturer and the technical assistance at RCF during the start of production.[6]

Out of the 24 coaches imported from Germany, all of them mostly being Air Conditioned chair cars,[10] the first lot were used for New Delhi-Lucknow Shatabdi Express on a trial basis. It didn't turn out be successful as the coaches' wide windows were targets of mischief and stone-pelting. Railways had to use sealing tapes to tape up the bruised windows.[8] When these rakes were brought into service, couplers came unstuck and the data collected from the passenger feedback showed that the air conditioning was not "very effective". They were withdrawn from service and after attending to the problems, Railways reintroduced them on the New Delhi-Lucknow Shatabdi Express and proved successful.[8][11]

The RCF began to manufacture other variants of LHB design like the air conditioned first class, AC 2 tier sleeper, AC 3 tier sleeper, hot buffet (pantry) car etc., from 2001 to 2002, and rolled out its first rake in December 2002. The first such rake was introduced for Mumbai-New Delhi Rajdhani Express in December 2003.[10] Up to March 2011, 997 LHB coaches were produced by the RCF.[12][13] All of these coaches are being used in premium trains like Rajdhani, Shatabdi, Duronto Express, superfast trains and have been offering better passenger comfort.[14] Soon, all the Duronto trains will be equipped with LHB coaches.[15]

Technical

The coaches are designed for an operating speed up to 160 km/h (99 mph) and could go up to 200 km/h (124 mph).[16] However, they have been tested up to 180 km/h (112 mph). Their length of 23.54 m and a width of 3.24 m means a higher passenger capacity, compared to conventional rakes.[17] The tare weight of the AC chair car was weighed as 39.5 tonnes.[18] They are considered to be anti-telescopic, which means they do not get smashed through a second coach or flip in case of a collision (chiefly head-on). These coaches are made of stainless steel and the interiors are made of aluminium which make them lighter as compared to conventional rakes.[8] Each coach also has an "advanced pneumatic disc brake system" for efficient braking at higher speeds, "modular interiors" that integrate lighting into ceiling and luggage racks with wider windows.[19] The improved suspension system of LHB coaches ensures more riding comfort for the passengers compared to conventional rakes. The air conditioning system of the LHB coaches is of higher capacity compared to the older rakes and is electronically controlled which is said to give passengers better comfort than the older coaches during summer and winter seasons. They are relatively quieter as each coach produces a maximum noise level of 60 decibels while conventional coaches can produce 100 decibels.

Each LHB coach costs between ₹ 1.5 Crore to ₹2.0 crore, whereas the power car which houses a generator costs about 3 crore .[16][20]

Production

Annual production of LHB coaches is around 400 per year for year 2013–14.[21]

  • During 2010–11, Rail Coach Factory, Kapurthala produced 300 coaches.[22] During 2012–13, the total number of coaches that were produced was 1680, while in 2013–14, RCF was able to increase the production to 1701 coaches.[23]

Production

  • Since 2001 onwards until March 2016, 4,020 LHB coaches were made by Indian railway various coache factories.[24]
  • During the 2008-09 Railway Financial Budget session, it was announced that after 2010 only stainless steel coaches will be manufactured.[25]
  • In 2009-10, 169 LHB coaches produced by Rail Coach Factory (RCF), Kapurthala, Indian Railway. In 2010-11, 316 LHB coaches produced by Rail Coach Factory (RCF), Kapurthala, Indian railways.[26][27] In 2011-12, 260 LHB coaches manufactured by RCF[28] In 2012-13, 470 LHB coaches produced by Rail Coach Factory (RCF), Kapurthala.[29]
  • In 2011, the Ministry of Indian Railways had approved the construction of a 300 LHB coaches per annum facility at ICF at a cost of Rs 252 crore. The foundation stone was laid in April 2012. It was inaugurated in July 2015 by Railway Minister Suresh Prabhu through video conferencing.[30]

During 2013–14, Integral Coach Factory produced 25 LHB coaches.[31] It plans to increase its manufacturing capacity of LHB coaches. It has set a target to manufacture 300 LHB coaches in 2014-15 and reach a capacity of 1000 LHB coaches by 2016–17.[32]
