Alcatel-Lucent and Transtelecom, one of Kazakhstan's communications service providers, have completed a $100m project to modernise the communications network supporting the country's Kazakhstan Temir Zholi (KTZ) railways.
Under the project, which was announced in December 2009, the company extended Transtelecom's fibre-optic network to 4,000km and upgraded a further 2,000km of existing lines.
The new network will improve communications between trains and centralised traffic control systems and support more advanced information systems to improve passenger safety, the company said.
In addition, the network will support the expansion of freight transport across Kazakhstan and to neighbouring countries.
The fibre-optic network will support advanced onboard and in-station passenger information systems as well as a variety of new broadband services, and will increase efficiency and punctuality of the train network.
