Emergency Plan G

A 1980 booklet issued by the New Zealand Railways documented nine plans for the emergency working of commuter trains between Wellington and Petone and Tawa. The booklet replaced one issued in 1974. The plans defined the actions to be taken should various sections of line become blocked.

This page summaries the plans and gives details for Plan G. This plan is interesting because it involved working trains through the Goods Yard and pilot working between Wellington Junction and Ngauranga. The plan was required when the UP main between Wellington Junction and Ngauranga was blocked.

Such working would not be possible today because the goods yard is no longer wired for the 1500V DC used by the commuter trains.

10L Shunt From Down Main at Ngauranga controls the movement of Up trains (under authority of Pilotman) from the Down Main (pictured), through 9 points, to the Up Main (February 2001).




Emergency Plans

GENERAL INSTRUCTIONS

The following procedure MUST be adhered to before emergency Working Plans A, B, C, D, E, F, or G can commence.

(1) The proposed route through Wellington Goods Yard must be inspected by the Inspector, Permanent Way, Wellington, (or his nominee), who will satisfy himself that track work is fit for passenger carrying rolling stock.

PLAN G Details

UP main line between WELLINGTON JUNCTION and NGAURANGA blocked by slip or other obstruction.

In the event of the UP main line between Wellington Junction and Ngauranga being blocked and it is necessary to work all traffic over the DOWN main line under pilot working, in accordance with Rule 86 and Automatic Signalling Regulations, the following arrangements are to be made:-

The Train Control Operator must IMMEDIATELY advise the Traffic Foreman at Wellington Station, the Yard Foreman, Wellington Goods, the Passenger Yard Foreman and the Signalman, "A" Signal-box and "B" Signal-box, of the position. On receipt of this advice UP HUTT VALLEY trains must NOT be dispatched from Wellington until authority has been received from the Train Control Operator for such trains to be worked over the alternative route as follows:-

The Yard Foreman, Wellington Goods, must IMMEDIATELY arrange for the clearing of H1 and H1A Goods roads. When this has been done, the Train Control Operator MUST be PROMPTLY advised. H1 and H1A roads must be kept clear of goods traffic until normal working has been resumed unless authorised by the Train Control Operator.

The Passenger Yard Foreman will provide a competent member to set the through route from the south end of G1 to H1A roads in the company of a Way and Works Branch member. To avoid the possibility of conflicting movements from the Goods Yard the Way and Works Branch member must also bolt for the through Goods Shunt Road the spring points which give access from this road to the J roads.

The provisions of the instruction on page 4 regarding the safe condition of the route must be adhered to.

The member provided by the Passenger Yard Foreman, working under the direction of Signalman, "A" Signal-box, will protect and hand-signal ALL movements through the area which must NOT again be used by other than UP PASSENGER services unless authorised by the hand-signalman. The hand-signalman MUST be selected and equipped in accordance with Rule 98 (h).

Goods Manager, Wellington, will provide a suitable member to act as Officer-in-Charge at Ngauranga and Area Traffic Manager, Wellington, will provide a suitable member to act as Officer-in- Charge at Wellington Junction. These members MUST work under the direction of Signalman, "A" Signal-box.

For the purpose of pilot working the section will be Wellington Junction to Ngauranga.

Area Traffic Manager, Wellington, will make the necessary arrangements to supply forms and a suitable member to act as pilotman, pilot working will be instituted from either Ngauranga or Wellington Junction as directed by the Train Control Operator.

DOWN trains will proceed from signal No. 10R (DOWN Starting from DOWN main) at Ngauranga to Wellington or Wellington goods yard via the usual route and will stop at No. 2RABC Outer Home signal to set down pilotman or pilot ticket. Signalman, "A" Signal-box, must NOT clear signal No. 10R at Ngauranga until authorised by Officer-in-Charge Ngauranga and must NOT clear signal No. 2RABC until receipt of advice from the Officer-in-Charge, Wellington Junction, that the pilotman has alighted or that the pilot ticket has been received.

UP HUTT VALLEY PASSENGER trains will depart from the passenger platforms on colour light signals which will authorise them to run beyond the north end of No.58 points where they will be hand-signalled over facing points at G1 through to H1A Goods Arrival road. Signalman, "B" Signa1'box, and Signalman, "A" Signal-box, will then route trains on colour light signals via H1 Goods Arrival and Shunt road on signals Nos 4A (shunt from H1A) and 24L (shunt and UP Starting from H1).

ALL OTHER UP HUTT VALLEY trains MUSTstopat signals Nos 18L (shunt and UP Starting from E4), 20L (shunt and UP Starting from T1), 22L (UP Goods Starting from K2), 24L (shunt and UP Starting from H1), or 26L (Shunt and UP Starting from J4), as the case may be, to pick up pilotman or pilot ticket.

UP MUTT VALLEY trains will proceed to the UP main line at Ngauranga, via No. 9points, on the authority of signal No. 10L(shunt from DOWN main), and will stop at signal No. 8L (UP Directing) to set down pilot man or pilot ticket.

Officer-in-Charge Wellington Junction must obtain the authority of Signalman 'A' Signalbox before despatching trains past No. 12LABC Up advanced Starting from Goods Signal.

The Signalman, "A" Signal-box, must NOT clear signal No. 8L until receipt of advice from the Officer-in-Charge, Ngauranga, that pilot man has alighted or that the pilot ticket has been received.





The Down Main - Ngauranga To Wellington Junction

The following photographs were taken in 2001. They are not of an actual run with a pilotman on board. I have not had the privilage of a journey over this section while Pilot working was in use.

10R Down Starting From Down Main. Down trains stop here for the Pilot or pilot ticket. Officer-in-Charge Ngauranga then authorises Signalman A-Box to clear 10R.

Up trains stop at 8L (behind the camera on the Up Main) to set down Pilotman or pilot ticket. Signalman A-Box must not clear 8L until authorised by the Officer-in-Charge.

9 points looking towards Wellington. The Down Main is on the left; Up Main is on the right.

Up trains cross here from the Down Main to the Up Main under authority of 10L Shunt from Down Main.

Automatic signal 411.

The Down Main passes under the Motorway. The NIMT Bridge over the Hutt road can be seen.

The Up Main is on the other side of the right hand wall.

Down train on the Down Main.

The Motorway is on the left. On the right is the embankment carrying the NIMT. The Up Main (which is blocked in this simulated single line working) is on the other side of the bank.

2R Down Outer Home. Down trains stop here to allow the Pilotman to alight or to hand the pilot ticket to the Officer-in-Charge Ngauranga. The Signalman A-Box must not clear 2R for Down trains without the authority of the Officer-in-Charge.

The Officer-in-Charge must obtain the authority of the Signalman A-Box before dispatching Up trains past 12L (at exit from Goods Yard).

The route taken by Up trains under Plan G. From the left - Up Main, Down Main and the road this train is on, the Goods Arrival and Departure.

Up Hutt trains exit the yard at this point, cross over to the Down Main and proceed to Ngauranga wrong line with a pilotman.

Down Hutt trains take the normal route on the Down Main.




Notes

  • I do not know if passenger trains ever ran through the goods yard. I remember three occasions as a commuter when a southerly undermined the track near Ngauranga and single line working was introduced between Ngauranga and Petone.
  • The yard wiring was removed sometime in the 1980s or 1990s.
  • B Box was removed sometime in the 1980s or 1990s.
  • There have been major track changes near G1 following closure of the East car sidings and the clearing of the site for the Stadium.
  • Who decides the order of trains? Train Control? Down Tawa trains must be slotted in.
  • Where do Up trains receive the pilot ticket? At 12L?
