Lower Hutt Signalling History

This page documents signalling and track layout changes at Lower Hutt.

My Lower Hutt - Melling page descibes signalling on that section in more detail.

From about 1989 Lower Hutt has been known as Western Hutt.

1905

A new Troup designed station opened and Lower Hutt to Petone duplicated. A 40 lever mechanical frame (10 levers in a ground frame) was installed. Tablet had been installed on the single line in 1901 (replacing Winter's Block) and remained in use to the north. Sykes Lock & Block was introduced from Lower Hutt to Kaiwharawhara in 1909. I do not know how this section was worked from 1905 to 1909. Note the use of the designation Inner Home for what today would be called a Directing signal. Read the text of S & I 34 dated 7th November 1905.

March 1922

Upper Quadrant Semaphores Three position signalling with upper quadrant semaphores was installed south of Lower Hutt. Up distant number 40 removed - its function taken over by intermediate signal 730. 6 Down Advance Starter converted to power operation. Trains arriving at Lower Hutt MUST whistle on approaching the Home Signals. See the text of S & I 377. Note that on the diagram south is now on the left hand side.

Note that 730 was two position - did it indicate either caution or clear i.e. act as a distant?

I am guessing at the meaning of the semaphore symbols.

September 1922

Three position signalling with upper quadrant semaphores was commissioned north of Lower Hutt.

The Down Distant was removed. A power operated Up Advance Starter was installed (in effect the Departure signal). Lower Hutt remains a two-position station.

Read the text S & I 395.

October 1940

Roadworks To allow the construction of a new road to the west of the loop the signal box was removed. It was replaced with a 23 lever Westinghouse L frame in the station building.

The station was resignalled with motor points and upper quadrant semaphores. Lower Hutt was a permanent Signal Cabin.

Prepare to reduce to Medium Speed

New Indication A new Prepare to Reduce to Medium Speed indication was introduced. The S & I circular stated that a "caution" indication on the top unit and a "clear" indication on the bottom unit is not a Signal Imperfectly Displayed. See the text of S & I 577.

October 1945

Scissors crossover in east yard converted to two simple crossovers. (S & I 612).




February 1954

The loop and scissors crossover were taken out of service. The Down Starting semaphore was replaced with a colour light signal but some semaphores remained. Lower Hutt, which was no longer on the main line to the Wairarapa, was a permanent signal box which also controlled 9 Down Departure (Melling).

The S & I was issued following the closure of the line north of Melling. The document included the following paragraphs:

For the time being the loop and other track connections at Lower Hutt not shown on the diagram will remain and turnouts not in use wil be secured for the running road.

For the purpose of lifting disused track north of Melling by work trains "All Trains Stop" boards have been provided for trains in both directions. Permission to pass these boards must be obtained by telephone from the Lower Hutt Signalman.

The Up Home signal at Melling worked automatically - the low speed indication was cleared on the approach of each train whether the Melling platform is occupied or not. The Down Starting signal at Melling (9) is classified as a Departure signal. See the text of S & I 690.

July 1958

Control of Lower Hutt was transferred to Petone. For the purposes of the Rules & Regulations Melling, Lower Hutt and Petone were one interlocked station under the control of the Signalman Petone. Petone was a permanent signal box. The Down Starting signal at Melling was reclassified from a Departure to an Outer Home. Hutt Valley Junction to Lower Hutt singled. Was this when last semaphore was removed?

August 1983

The Lower Hutt Yard had been closed in 1981 (Rails Magazine June 1981). Just 80 Down Outer Home From Melling (at Melling) and 78 Down Home From Melling (at the junction) remained on the Branch (S & I 1969) - see my Lower Hutt - Melling Signalling page. There were no fixed signals at Lower Hutt but the line was track circuited. North now at right of diagram.

Lower Hutt 1969



October 1996

In 1996 all signalling was removed from the Melling Branch so there were no longer any track circuits at Lower Hutt (S&I 2500).




Christmas 2013

Petone, including the Melling Branch, was re-signalled. Lower Hutt Station is now in an axle-counter area but there are no fixed signals at Lower Hutt.
