Grodzisk Mazowiecki

Grodzisk Mazowiecki is the junction station where the Central Railway Main Line begins. At the same time, a four-track section of lines nos. 1 and 447, leaving Warsaw, ends here - further on, long-distance and suburban trains already use a single, double-track route towards Zyrardow. However, the exit of long-distance trains in the direction of Skierniewice is collision-ridden - it requires crossing a track with the opposite direction of traffic. A comprehensive modernisation of the station was carried out in 2014-2015, after which it has 6 main tracks. At the platforms there are 2 main tracks - suburban main tracks (3 and 4) and additional main track No. 14. Long-distance tracks No. 1 and 2 have no platform edges, as does track No. 11. The platforms are connected to the station and the north side of the village via a footbridge and subway. Behind the platforms, there are 2 lay-back tracks used for turning trains that are terminating. In the turnout head on the Zyrardow side, however, the first turnouts in Poland are built in, enabling trains to travel in the turning direction at speeds of up to 130 km/h. Train traffic is managed by signal box 'Gr', which has computer equipment including light signalling.[1]
