Trentham Station

At Trentham the double line from Wellington to the Wairarapa becomes single. Usually all trains use the Up platform. However, when there are races at the adjacent Trentham racecourse the Down (Racecourse) platform, is used. From this platform punters can walk directly to the racecourse.

On these pages I document race day activity, some rare workings observed in early 2006 and the signalling arrangements. I also document Trentham as it is for most of the year.

As far as I know Trentham is the only unmanned station in the Hutt Valley that still has glass in the windows. Net curtains add to the pleasing effect.

Trentham Station Overview

Junction. 18 points are the single to double line junction. Until early 2007 these points were controlled from Upper Hutt. Upper Hutt could not operate 19 & 13 points, requiring the station to be switched in on race days.

On 6th February 2007 control of Trentham was transferred to the Network Control Centre (NCC), the signals renumbered and the station panel decommissioned. I understand that the NCC can control 19 & 13 points.

Racecourse Platform. For approximately 360 days of the year all trains use the Main platform. On race days the Racecourse platform is used. Until early 2007 it was necessary for Trentham to be switched for trains to use the Racecourse platform.

Now that Trentham is controlled from the NCC the concept of switching-in is presumably no longer meaningful.
