Indian Railways achieves big feat! India’s longest electrified rail tunnel built by Indian Railways is not just an engineering marvel but also a game-changer for freight operations across the railway network. The longest electrified railway tunnel – 6.7 kilometres long – in the new 112-km long broad gauge (BG) line between Obulavaripalli-Krishnapatnam is expected to result in major monetary benefits. Indian Railways is saving almost Rs 7.5 lakh per coal rake, since the commercial operations on this route began, a railway official told Financial Express Online. The horseshoe-shaped tunnel has been constructed through the New Austrian Tunnelling Method (NATM) spanning across a length of 6,600 metres. The total anticipated cost of the constructed tunnel is Rs 437 crore, while that of the whole project is Rs 1,993 crore. The tunnel has been provided with LED lights at intervals of 10 metres.
According to CH Rakesh, Chief Public Relations Officer (CPRO), South Central Railways (SCR), four commodities namely coal, iron ore, limestones, and fertilizers are being loaded on the freight trains from the Krishnapatnam port and deported to the western parts of the country. Read More
