The National High Speed Rail Corporation Limited (NHSRCL) has commenced an aerial survey for the construction of the high-speed railway corridor between Mumbai and Nagpur. The survey is being conducted to prepare the detailed project report (DPR) for the railway corridor. The survey will provide ground data details in four months.
Ground survey is a crucial activity for any linear infrastructure project as the survey provides accurate details of areas around the alignment. This technique uses a combination of laser data, global positioning system (GPS), flight parameters and actual photographs to give accurate survey data,” said a senior NHRSCL official.
LiDAR Survey for the Preparation of Detailed Project Report for Mumbai-Nagpur High Speed Rail Corridor has started today, where an aeroplane fitted with state of art Aerial LiDAR and Imagery sensors took the first flight and captured the data related to ground survey.
The spokesperson said, “During the Aerial LiDAR survey, 150 mtrs of area around the proposed alignment is being captured for the survey purpose. After the collection of data, Three Dimensional (3D) Topographical map of corridor of the proposed alignment on a scale of 1:2500 will be available for designing of the vertical & horizontal alignment, structures, location of the stations and depots, Land requirement for the corridor, identification of project affected plots/structures, Right of Way etc.”To provide clear pictures of the structures, trees and other minute ground details,100 megapixel cameras are being used for the LiDAR survey.NHSRCL has been entrusted to prepare the Detailed Project Reports for seven (7) High Speed Rail Corridors and LiDAR survey technique will be used for ground survey in all the corridors.The proposed plan for Mumbai Nagpur HSR Corridor (approx 736 km) will connect Mumbai city with cities/towns like Nagpur, Khapri Deport, Wardha, Pulgoan, KaranjaLad, Malegaon Jahangir , Mehkar, Jalna, Aurangabad, Shirdi, Nashik, Igatpuri, Shahapur.
Mumbai-Nashik-Nagpur Hi-speed corridor is amongst the seven hi-speed corridors, including Ahmedabad-Delhi, Delhi-Varanasi, Mumbai-Hyderabad, Mysuru-Bengaluru-Chennai and Varanasi-Kolkata.
NHSRCL has stated that the trains will be operated at a speed of 320km per hour. Passengers travelling by rail from Mumbai to Nagpur are likely to save up to 50% of their commuting time after the route is ready.
