What is an ESTW L90?

An ESTW (Elektronisches Stellwerk) is an electronic signal box. From it the dispatcher works the points, signals and level crossings of a German railway station, with monitors, a mouse and a keyboard instead of levers.

L90 is one of the ESTW types used in Germany, built by SEL, later Alcatel and Thales. Its Lupe monitor shows the station tracks, signals and train numbers, and you set a route by clicking from signal to signal or by typing a command.

Traksim is an ESTW L90 simulator: a desk with its monitors, with commands and operating rules modelled on the real signal box and simplified in places. You do not need to know railways, the tutorial walks you through your first shift.
