The contract, which is Siemens' largest ever rail automation order,
covers the supply and installation of its Trainguard MT train control
system, Sicas electronic interlockings, and switch machines across the
170km network, and includes 25 years' mainteance. Siemens will also
equip the fleet of 135 eight-car trains and maintenance vehicles.

2014 and will be rolled out over the remainder of the network on a
line-by-line basis by 2018.

The S-Train network will be converted initially to allow Semi-Automated
Train Operation (STO), which will allow trains to run independently of
fixed line sections in moving blocks. This will shorten headways on the
busiest sections from 120 seconds to 90 seconds. The contract includes
an option for conversion to full Unattended Train Operation (UTO) at a
later date.

Trainguard MT provides continuous data communication between trackside
and onboard via a wireless local area network (WLAN) link, meaning
every train can be accurately located without the need for axle
counters or track circuits. The optimum speed and headway are
constantly recalculated and transmitted to the onboard control system.
