POSS at the Metro of Stockholm

Storstockholms Lokaltrafik (SL) first implemented POSS at the Gullmarsplan station in 2005. The success of this project led to a network-wide roll-out of POSS on all Tunnelbana lines in 2007, for which approximately 150 points were connected to POSS. Another 150 points were connected on the Tunnelbana and Roslagsbanan (regional lines) between 2009 en 2011. Storstockholms Lokaltrafik (SL) is the organisation that runs all public transport in the Stockholm area.

POSS wheel shunt detection

After the installation of a new rail lubrication system there was a fear that the oil film would disturb the track circuits. The customer therefore decided to install a POSS wheel shunt application at the station of Ostermalmstorg in 2006. POSS now checks every train passage on correct wheel shunt.
