Project Highlights:
- BSRP is a flagship project being executed by K-RIDE, a joint venture of Govt of Karnataka and Ministry of Railways.
- The 4 corridors of BSRP with about 148 km of Railway line will act like a connecting bridge between Rural and Urban areas. For details, see the system map provided in the bid document.
- The K-RIDE infrastructure project is being built at a projected cost of ₹ 15,767 crore. It will provide a delightful travel experience for travellers across different sectors and streams. The trains will be air conditioned (Metro-like with automated double-leaf sliding doors).
- The 57 suburban stations will be enabled with Metro-like facilities and promote smart card-based cashless travel for suburban Railway users.
- BSRP planned to setup two (2) nos. of depots at Akkupete (near Devanahalli) in North Bangalore spreading in about 49.42 Acres area and at Soladevanahalli (Near Chikkabanavara) in South-West Bangalore in an area of about 50 Acres. K-RIDE plans to construct about 77 stabling and 16 inspection & workshop lines to cater rolling stock for all the 4 corridors.
System Description of Bangalore Suburban Rail Projects The Rail Systems are based on:
- Continuous Automatic Train Control (CATC):
- This is based on CBTC which consists – Automatic Train Protection (ATP), Automatic Train Operation (ATO) and Automatic Train Supervision (ATS) sub-systems.
- The train borne Automatic Train Control system will consist of Automatic train Operation (ATO) and Automatic train Protection (ATP). This will work on a fixed block principle.
- Automatic Train Protection (ATP):
- The primary function of the train control system. This sub system will be inherently capable of achieving the following objectives in a fail-safe manner. Line side signals will be planned at diverging routes (i.e., at points & crossings), which shall serve as backup signalling in case of failure of ATP system.
- However, in such cases, train speed will automatically be restricted to 25 km/h.
- The cab-borne equipment will be of modular sub-assemblies for each function for easy maintenance and replacement.
- The ATP assemblies will be fitted in the vehicle integrated with other equipment of the rolling stock.
- Automatic Train Operation (ATO):
- The system will operate the trains automatically from station to station within the safety envelope of ATP and open the train doors on the correct side. In conjunction with ATP/ATS, ATO can control the dwell time at stations and manage the train running in accordance with the headway/ time table.
- Automatic Train Supervision (ATS):
- A train supervision system will be installed to facilitate the monitoring of train operation and also remote control of the station.
- The train supervisor will log each train movement and display it on the workstation with each Traffic Controller at CC and on the workstation placed in the Station Control Room (SCR) with each Station controller.
- The centralised system will be installed in the Control Centre (CC). The CC will have a projection display panel showing a panoramic view of the status of tracks, points, signals and the vehicles operating in the relevant section/whole system providing the following main functionalities:
- Automatic Route Setting
- Automatic Train Regulation
- Continuous Tracking of Train Position
- Display Panel & Workstation Interface
- Link to Passenger Information Display System for online information
- Computation of train Schedule and Timetable
