Boards

This page shows a selection of the boards that are observed by drivers in the Wellington network. It does not claim to show all boards currently in use.

I am not sure if details belong on a signalling site or a safeworking site. I have decided to include them in the signalling section.

Boards

Compulsory Stop Outer Warning

The Compulsory Stop Protection Outer Warning board is erected 1200m from the Inner Warning board.

CSP caution board

Compulsory Stop Inner Warning (Whistle)

The Compulsory Stop Protection Inner Warning (Whistle) board is erected 300m from the Compulsory Stop Protection board.

Whistle Board

Compulsory Stop Board

A Compulsory Stop board is equivalent to a temporary stop & stay intermediate signal fixed at Stop. It is used to protect work sites and can only be passed on the authority of the Person In Charge (Sierra Echo in this case).

CSP boards are not used within station limits where an alternative form of protection is used.

The board is erected 500m from the worksite.

CSP Stop

Worksite Limit Board - View From Worksite

Defines the limit of a Compulsory Stop Protection work site. The board is for the guidance of track staff and is visible from within the worksite. The board ensures that the 500m safety margin between the Compulsory Stop Board and the worksite is maintained.

Work Area Ends Board

Worksite Limit Board - View From Outside Work Area

Defines the limit of a Compulsory Stop Protection work site. Informs the train driver (who has been authorised past the Compulsory Stop Board) that he is about to leave the safety buffer and enter the worksite.

Work Area Begins Board

Danger Stop

I believe that this is an absolute stop - i.e.unlike All Trains Stop boards a train cannot be authorised past the Danger Stop board.

This board protects a siding at Woburn that is used for the storage of ballast.

Danger Stop Board

Non-Standard Danger Stop

A "rubber tyre" stop board. It is a Signal Imperfectly Displayed so under the relevant rule drivers must treat this as a Stop signal.

This example is on the Gracefield Industrial Siding.

Non_standard danger Stop

All trains Stop

Used where special authority is required to pass the location. Examples are when special procedures were implemented at the Up Departure signal at Wellington after a wrong side failure with a three-colour LED signal; defining the limits of running when there is a block of line; requiring permision to be obtained before entering a yard.

This is a three-in-one photo. In addtion to the All Trains Stop board there is a CTC Begins board and an arrow indicating which track the signal applies to.

The smudge is on the train window, not the camera lens.

All trains stop board

All trains Stop

An older version of the All Trains Stop Board.

This can be seen near the Johnsonville Up Departure signal in Wellington.

Wrong Line Limit Board

Used to define the limit of wrong line running in double track territory. Typically used where a set of points are not protected by a ground light.

This is Waterloo Board number 1.

Wrong line limit board

Permanent Speed

Permanent Speed boards indicate exceptions to the authorised maximum speed.

This reflectorised board at Epuni is seen at night.

I believe that the board was installed when it was proposed to increase the maximum authorised speed of the Wairarapa trains. I do not know if the proposal has been implemented.

Slow 90

Permanent Speed

Permanent Speed boards indicate exceptions to the authorised maximum speed. This board has been modified to indicate which trains the board applies to.

This applies to up Johnsonville trains at the throat opposite A-Box.

The board has been fixed on a SLOW 15 (mph) board dating from the 1970s.

Express Freight

A permanent speed board applying to express freight trains. The signal spacing is insufficient for freight trains and such trains must therefore travel at less than normal speed.

This is an example of a SLOW board indicating a reduction in authorised speed. In other situations a SLOW board can authorise a higher speed.

This board faces up trains at Wallaceville.


Express freight board

Slow through Junction

A permanent speed board applying to trains travelling through a junction. Medium Speed is defined as 25kph. This board authorises a higher speed.

This is an example of a SLOW board authorising an increase in permitted speed.

To be seen on the up main at Melling Junction.

Slow through turnouts

Normal Speed

This permanent speed board has a non-standard shape. The board on the other side of the traction pole shows the usual shape for such a board.

This board is passed by up trains after they have cleared Wellington Junction.

Normal Speed Board

Curve Warning

Curve Warning poards indicate that a speed reduction of more than 15km/h is required on the curve ahead.

This board is on the down main at the south end of Woburn.

Curve

Curve boards showing the maximum speed in kilometres per hour are erected near curves where a reduction in maximum speed is required.

Curve boards are preceeded by curve warning boards.

This board is north of Paraparaumu. The board was erected for the Silver Fern railcars which have an authorised maximum speed of 110kph.

Curve Board

Shunting Limit

Used when a train is permitted to enter a single line section for shunting or must run wrong line. An example of the former is at the north end of Featherston.

This example is at Woburn where shunts departing the Industrial Siding for Wellington must first set back onto the Down Main. Note the belt and braces approach - the ground light is fixed red.

Shunting limit board

Woburn Signs

One of two special signs relating to the special operating procedures on the Gracefield Industrial Siding.

Woburn board

Outer Temporary Speed

The Outer Temporary Speed Board indicates Be prepared to reduce speed as indicated by board. The start of the restriction is indicated by an Inner Speed Board.

At the south end of Upper Hutt.

Temporary speed restriction

Inner Temporary Speed

Defines the limits of a temporary speed restriction. When the first inner ( C) board is passed the train's speed must not exceed that on the Outer Board. Normal speed may be resumed after the last vehicle has passed the second inner ( T) board.

C Commence?

T Terminate?

On the down main at Wallaceville.

C board

Heat Warning Board

Heat Boards are acted on after Control advises that heat restrictions are active. Specific procedures are in place to determine when the restrictions apply.

The start of the restriction is marked by an H board.

This board was photographed at Johnsonville station.

Heat Inner Board

An H board marks the start of the heat restriction.



I do not have a photo of this board.

Route Indicators

As part of the construction of the Wellington Urban Motorway in the 1960s changes were made at Wellington Junction. The signalling was not changed. Subsequently these boards were erected to indicate to drivers the route set up.

NS Normal Speed Tawa - the diverging route.

MS Medium Speed Hutt - the straight through route.

NS,MS

Electric Engine Limit

A sign for EMU drivers at Paraparaumu long after the last electric engine ran in the Wellington network.

As I write this (Dec 2008) the SE set with Eo locomotives is being readied for service. The set will not run to Paraparaumu.

Electric Limit Board

Track Warrant Intermediate Board

A notice board provided between stations or sidings to identify a location which may be used to designate a limit for a track warrant.

This board is at Carterton.

IB Board

Track Warrant Station Warning Board

A notice board that marks the approaches to a Warrant Station or the end of TWC territory, where a fixed signal is not provided for the purpose. The points symbol indicates that there is no points indicator at the station facing points.

This board is north of Featherston at the 60km peg and indicates the approaching end of Track Warrant territory - Featherston is an interlocked station in CTC territory. This station board in effect acts as a distant to the Featherston Down Outer Home signal.
