Technical
The train is equipped with LHB coach. They are considered to be "anti-telescopic", which means they do not get turned over, if the train derails or gets involved in a collision. These coaches are made of stainless steel and the interiors are made of aluminium which make them lighter as compared to conventional rakes. 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. The improved suspension system of LHB coach ensures more riding comfort for the passengers compared to conventional rakes. The air conditioning system of the LHB coach is of higher capacity compared to the older rakes and is controlled by a microprocessor which is said to give passengers better comfort than the older coaches during summer and winter seasons. They are relatively quieter as each coach can produce a maximum noise level of 60 decibels while conventional coaches can produce 100 decibels. Each LHB coach costs between Rs 15 million to 20 million, whereas the power car which houses a generator costs about 30 million.
