30 INDUSTRIAL PREFABRICATION OF RAILWAY SLEEPERS Baku's congested subway network will be expan- ded from 36.7 km to 119 kilometres by 2030, while in Thailand 1.73 million railway sleepers will be produced over the next few years for infrastruc- ture development and for connecting rural areas to the boom cities – such mega-projects are only feasible through the industrial precasting of rail- way sleepers. As experts, we have been automating con- crete sleeper plants since the 1980s. For example, Vollert developed a circulation system for the pro- duction of the concrete sleepers for the 57-km long Gotthard Base Tunnel, based on the Low Vibration Track System, for the Swiss company Vigier Rail. In 2011, two production plants for a total of 1.1 million prestressed concrete sleepers were com- pleted in just twelve months for Inkol Insaat in Turkey – 180 sleepers per hour. 450 quadruple moulds are constantly in circulation in highly au- tomated plants. In Monterrey, Mexico, GIC has been using a Vollert system for the production of concrete sleepers for the Central American and US markets since 2014. Here, we not only supply the plant produc- tion technology but also provide engineering ser- vices for the planning and implementation of track systems. 1 Concrete sleeper mould circulation system 2 Sleeper forms in the curing chamber 3 Sleepers after the production process 1 2 3
