HYDERABAD: As the detailed designs of metro rail overbridges are getting necessary approvals from South Central Railway engineers, Hyderabad Metro Rail managing director NVS Reddy on Monday discussed with them the modalities and requirements of ‘traffic blocks’ (stoppage of trains for three hours each time to launch metro rail bridge segments).
The ‘traffic block’ will be enforced initially for the Bharatnagar metro rail crossing and later for the other seven crossings.
Metro rail is crossing the railway tracks of SCR at Alugaddabavi, Chilkalguda, Oliphant bridge and Bhoiguda near Secunderabad railway station and at Bharatnagar, Begumpet, Lakdikapul and Malakpet.
While the railway tracks at Bharatnagar and Begumpet are at the ground level, the track at Lakdikapul is below the ground level. As for the other five places, the railway tracks are at a high level needing the metro rail overbridges to cross them at double the height _ ranging from 35 feet to 74 feet _ leaving enough clearance for double-decker trains.
Similarly, keeping the requirement of the railway for future laying of tracks in mind, the obligatory span lengths are also designed for large lengths ranging from 128 feet to 272 feet.
NVS Reddy met SCR general manager PK Srivastava and discussed the metro rail crossing (metro overbridges) over the tracks of Indian Railways. Reddy informed the general manager that the requirements of railways were taken into consideration while designing metro rail bridges by L&T engineers under the guidance of HMR experts.
While Oliphant and Bhoiguda bridges will be built with steel, the other six will be concrete bridges.
After discussing the launching methods and the time required for the ‘traffic blocks’ with his senior officers, Srivastava assured Reddy that arrangements would be made from railway side to facilitate Bharatnagar metro rail bridge construction in the next few days and the remaining bridges as per the requirement of HMR.
