,

The forthcoming resignalling of Cardiff station area is a large complex undertaking and Atkins invited Rail Engineer along to the project offices at Newport to learn about the latest extension planned for the South Wales Control Centre (SWCC).

The Cardiff area was previously resignalled back in 1966 with the commissioning of Cardiff power box, with standard BR Western Region Henry Williams entrance switch/exit button panel for route setting with ‘E10K’ relay interlockings, similar to that at Swindon described in issue 131 (September 2015).

The long panel was split into two sections with the left portion covering the South Wales main line from Marshfield in the east through Cardiff Central station main line Platforms 0-4 (bay Platform 5 no longer exists) to Pontyclun in the west. The right section covers the valley lines from Cardiff Queen Street through Cardiff Central platforms 6 & 7 to Penarth, Cadoxton and Radyr (exclusive).
