Case Study - Curved Doors

A national train operating company needed to modernise their existing toilet door solution to ensure they complied with PRM TSI 2008/164/EC legislation regarding disabled access.

We developed an innovative curved actuation solution that provided syncronised, telescopic door operation, either electrically or pneumatically. The solution incorporated a locking system and emergency access override, and complied with all standard rail door specifications including obstacle detection.

The result was an increased aperture when the doors were opened, allowing improved wheelchair access, with push-button operation making it easier for passengers. The application-specific solution fully met the needs of the customer, and ensured compliance with all current and future legislation regarding disabled access.

Case Study - Step Control

An underground train operator faced the problem of an excessive gap between the train door and the platform, which created a safety risk for passengers. In addition, the gap between the doors and the platform was not consistent, and varied between stations.

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

Our engineers 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 size of the gap.

Due to the strict envelope size, our solution used only 50% of the space of a traditional step system. It included all the required standard safety features, including obstacle detection and could be integrated into the existing door control system.
