\r\n\r\nThe contract includes design, manufacture and supply of the CBTC system which will enable automatic train operation and increase network capacity. It will also completely replace the existing train control, signalling and train supervision systems.\r\n\r\nCBTC will be installed first on the Ring Line which connects the southwest of Amsterdam to the west by April 2015 with all of the work conducted at night to avoid disruption to services. The entire CBTC rollout will be completed network in 2017.\r\n\r\nThe municipality is investing Euros 4.5bn in the network over 20 years, which includes Euros 800m for new trains, systems and facilities. CBTC procurement has been conducted in parallel with the introduction of the new train fleet, which is also being supplied by Alstom, after the company secured a Euros 200m order for 23 Metropolis metro trains in February 2010. The trains are currently being delivered and will enter commercial service in the autumn.
