CUSTOMER CHALLENGE

An underground train operator had an issue where the gap between the train doors and the platform was excessive, creating a safety risk for passengers.  This issue was further complicated by the fact that the gap between the doors and platform was not consistent, and varied between stations.

The customer therefore required a variable step which would fit the gap at any station.  Any solution also needed to fit within a very restricted space beneath the existing door system.

NORGREN CHALLENGE

With over 30 years experience in the rail industry, Norgren engineers were able to developed a range of cushioned, telescopic cylinders that could be mounted below the existing door system.  By applying a set pressure, this cylinder system would fill the gap between the train and the platform regardless of the width of the gap.

Due to the strict envelope size, the Norgren solution utilised only 50% of the space of a traditional step system, and was able to fill the gap of any of the platform widths.

The Norgren design also included all the standard safety features required on a door step system e.g obstacle detection, and was able to be fully integrated into the existing door control system.

This application specific solution, exactly matched the needs of the customer and provided a more reliable and far safer step system for the train passengers.
