Wellington Third Track

A record of the changes at Distant Junction and the Throat during the installation of the third track in 2009 and 2010. The work involved the installation of a third main between Distant Junction and A-Box as part of the Wellington Regional Rail Project (WRRP). Note that Distant Junction is also known as Wellington Junction.

Distant Junction and the Throat are both under the control of A-box, although Train Control could log on and control the junction if necessary.

I plan to expand his site to provide more information about A-Box, including photos.

A computer game or the real thing? (November 2009).

At the completion of the work described on this page Train Control could see the tracks from Ngauranga to the platforms. The Junction was controlled from a work station in A-Box but Train Control could log on and control the junction if need be. The platform area was still controlled by the A-Box signalman from the 1936 26L frame.

In a separate project the crossovers at Ngauranga were removed and axle counters installed. Resetting the axle counters is done by Train Control.
