  • Vice President inaugurated the country’s longest electrified rail tunnel between Cherlopalli and Rapuru and the electrified railway line between Venkatachalam and Obulavaripalli.

About the tunnel

  • The 6.7-km-long tunnel is an “engineering marvel” and said it would provide viable rail connectivity between the Krishnapatnam Port and the hinterland for the seamless movement of freight.
  • It also reduces the distance for trains coming from Guntakal Division to Krishnapatnam by 72 km and eases traffic density in the Obulavaripalli-Renigunta-Gudur section.
  • This newly commissioned line of 112 km reduces the travel time to five hours as compared to the 10 hrs earlier for a goods train from Krishnapatnam Port to Obulavaripalli.
  • Besides facilitating operation of freight trains the new line would also provide the shortest path on the Chennai-Howrah and Chennai-Mumbai rail routes.
  • It would also ease congestion of both passenger and freight-carrying trains in the Vijayawada-Gudur-Renigunta-Guntakal sections.
