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.

Third Track Signalling & Interlocking Circulars

This is a list of S&I circulars issued during the third track project. I have not posted the S & I circulars on this site because of copyright and the size of the PDF files.

2774 July 2008.

2924 (Draft only) August 2009 Changes to F1 and E3 roads.

2932 September 2009 CBI installed at Distant Junction. Signals renumbered.

2941 Queens Birthday June 2010. The final arrangement, although some signals were fixed at stop and the Down Main did not come in use until July 2010.




Control Of Wellington Station

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.
