Indian Railways is actively planning to develop a compatible medium-speed track to run a train at a speed of 200 km/h at surface level near the existing track between Bangalore and Secunderabad as a greenfield project at an estimated cost. at Rs 30,000 crore.
While the total length of the existing track between the two cities is 622 km, the railways are planning to reduce it to 503 km from Umdanagar near Secunderabad to Yelahanka in Bangalore under the Gati Shakti initiative.
Estimated at around Rs 60 crore per km including low side walls on both sides, the proposed route is an attempt to save costs by avoiding multiple detours.
Fences or side walls on both sides of the track are essential for semi-high speed trains. It has been proposed to construct 1.5 meter high sidewalls along the new track to provide an exclusive right of way for mid-high speed rail operations.
The elevated road with viaducts like the RRTS corridor between Delhi and Meerut or the Mumbai-Ahmedabad high-speed rail line is expected to cost around Rs 300 crore per km.
Due to the Road Over Bridges (ROB) in urban areas, an elevated track along existing tracks would require multiple detours, resulting in the requirement for a number of vertical and horizontal curves.
Currently, the railways are upgrading two routes between Delhi-Mumbai and Delhi-Howrah to run trains at a speed of 160 km/h.
However, ruling out the option of upgrading the existing track to 200 km/h level, the railways are now reportedly exploring the possibility of developing a semi-rapid track at ground level as a demonstration project to begin with.
According to the plan, a new line would be built with a separate train control system and signaling close to the existing track for which a detailed project report would be commissioned shortly. The locally developed signaling system Kavach meant a speed of 160 km/h and more.
The ambitious Gati Shakti project linking two IT cities is still at the drawing board stage, preparatory work has started for the detailed project report.
The railways recently launched tenders for the manufacture of 200 Vande Bharat trains with a maximum speed of 200 km/h.
As part of the rolling stock modernization plan, the railways are preparing for modern systems such as articulated bogies or tipping cars, state-of-the-art technology as well as an upgraded version of the railway communication system.
Also, there would be 302 Vande Bharat trains with a speed of 160 km/h. Thus, our rolling stock becomes compatible for semi-high speed operation, said a senior official from the Ministry of Railways.
