NEW TRAIN PROTECTION WARNING SYSTEM FOR CHENNAI - ARAKKONAM SECTION

Southern Railway extended the Train Protection and Warning System (TPWS) currently deployed in the Chennai Beach – Central – Gummidipoondi EMU Sector to the 68 Km Chennai – Arakkonam section.




The Eurpoean Train Control System (ETCS) Level 1 solution, known in India as Train Protection and Warning System (TPWS) o­n the 68 km Basin Bridge – Arakkonam section in Chennai Division of Southern Railway was inaugurated by Shri Akhil Agrawal, Director General (Signal and Telecommunication) Railway Board, at Ambattur Station today 16thDecember 2016, in the presence of Shri H.K.Agarwal, Additional Member (Telecom) Railway Board, Shri A.V.Siva Prasad, Chief Signal & Telecommunication Engineer, Southern Railway, Shri Anupam Sharma, Divisional Railway Manager, Chennai Division, invitees from Institution of Railway Signalling and Telecommunication Engineers (IRST) and Indian Railways.




The project involves linking up about 169 signals o­n the Chennai – Arakkonam route and laying track – side equipment (installation and wiring of Line side Electronic Units and their interfacing with balises (Balise is an electronic beacon) installed o­n the track. 82 EMU trains fitted with o­nboard system ply between Gummidipoondi – Chennai – Arakkonam section with this enhanced safety system. The TPWS, which deploys the state of the art European Rail Traffic Management System (ERTMS – Level 1) technology, will not o­nly warn drivers of obstructions ahead but help regulate speed of trains and in dire cases, even activate emergency braking systems automatically in case of failure of the driver to heed warning signs. TPWS provides additional layers of safety in a fully automatic signalling section like the Chennai Railway Division without compromising o­n the density of traffic or the speedy despatch of train services every ten minutes. This system also guides motormen during poor visibility of signal due to foggy weather conditions. The system facilitates running trains at maximum permitted speeds, allows EMU drivers to slow down to stipulated speeds and activates emergency braking, to prevent collision in case of signal violations or over speeding past a red signal. The system uses o­n board computer consoles, or the Driver Machine interface, connected via wireless to track-side balise devices that use electro – magnetic induction to change the signal aspect from the default green to red whenever a train rolls by.


Further similar Train Protection Works have been sanctioned by Railway Board, New Delhi in the remaining Suburban sections of Chennai Division now provided with automatic signalling o­n the Chennai – Tambaram – Chengalpattu and Arakkonam – Jolarpettai sections at a cost of Rs.200 crores. These projects are being taken up by Southern Railway o­n priority.
