ALSTOM has won two signalling contracts to support Turkey’s General Directorate of Infrastructure Investments (AYGM) and Istanbul Metropolitan Municipality.
The AYGM contract is for the 201km 250km/h Bandirma - Bursa - Yenisehir - Osmaneli (BBYO) line. Alstom will supply Interflo 250 and 450, ERTMS Level 1 and 2 and deploy the entire interlocking system including Traffic Control Centre (CTC) through Kalyon Insaar Sanayi ve Ticaret.
Alstom will also install a smart object controller with the signalling system to eliminate the risk of obsolescence with legacy systems. This provides capability for the line’s signalling systems to interface over modern fibre-based digital networks and GSM-R to increase reliability, performance and functionality. BBYO will as a result be fully interoperable for all trains operating on the Turkish network.
The Istanbul Metropolitan Municipality contract covers the 11km Cekmekoy - Sancaktepe - Sultanbeyli (CSS) metro line. Through a joint venture consisting of Dogus Insaat ve Ticaret, Yapi Merkezi Insaat ve San and Ozaltin Insaat Ticaret, Alstom will supply, test and commission the entire signalling for the line including the supply of wayside equipment for eight stations and CBTC for four new trains.
The driverless system is designed to shorten headways between trains by 90 seconds. CSS has the capacity to carry 120,000 passengers per hour.
