The Signal Cabin currently in use at Mussel Pool station controlling the northern section of the yard, was originally used at the western end of Collie Yard controlling the junction of the yard to the mainline.

Bunburys Vintage Train passes the Collie signal cabin at the start of its return journey to Bunbury.   Oct 1980.

After being made redundant by Westrail, BBR purchased and relocated the 7 Lever cabin to Whiteman Park.

A small group of BBR members set out early on the Saturday morning 20/4/1987 for Collie where they met up with a local representative of the transport company assisting with the move of the Collie Cabin. With both the truck and the crane on site the crane was attached to the side of the cabin where it then dragged the cabin down the embankment sideways, having earlier dismantled the entry and stairs. At the bottom of the bank the cabin was carefully manoeuvred with the crane to end up sitting "face down" on the tray of the truck with the roof overhang, hanging over the back of the truck. The BBR members present expressed concern as to the suitability of this arrangement and were assured that all would be OK!!. The cabin was duly secured in this arrangement and returned to the company yard ready for an early morning departure for Perth the next day. The BBR crew returning to Perth that evening.

The former Collie Cabin is loaded onto a contractors truck in Collie. April 1987

The cabin arrived at Mussel Pool on the 21st of April 1987 after a somewhat unusual journey.

The truck was due for an early departure from Collie with an aim to arrive at Whiteman Park around 10.30am. 

11.30 came around and after a few phone calls it was soon realised that the truck had been delayed en-route. Much later in the afternoon the cabin eventually turned up on a completely different and much larger truck. Interrogation of the new driver of the new truck revealed that the original truck and driver had made it as far as the town of Harvey where upon he was pulled over by the local police, as the cabin roof was obscuring his rear indicator/brake lights. It was soon also determined that the load was over legal height for transportation and the police insisted that the load be transhipped to a more suitable vehicle. Hurried phone calls to Collie mobilised another of the companies trucks and a crane was sourced locally to effect the transfer. Some hours later the cabin was on the move again. Around 4pm the new truck rolled into the car parks at Mussel Pool. The local crane hire co. was duly contacted and arrived on site shortly after and the cabin was unloaded from the truck and put into place. It was later moved a little further up the hill to its current location by park management to enable a new extended platform to be built for Mussel Pool station. 

Bennett Brook Railway was very grateful to the trucking company as this move was was effected at no cost to the railway

After installation and restoration the cabin was initially used as a "Ticket Office" and "Staff" cabin, providing shelter for the ticket seller on poor weather days until the opening of the Nungarin station building in 1991.

The Collie cabin is still in use today even though use of the larger Cottelsoe cabin across the track has been mooted since 1988 to enable an expansion of facilities

The Mussel Pool / Collie Cabin lever frame consists of seven numbered and colour coded levers. 

These are assigned as

1. Loop Starting Signal - [ Red Lever] controlling the starting signal adjacent to the depot points. This signal is used to give the road for north bound trains leaving Mussel Pool from the loop; and for call-on indication from the loop onto the main line (ie point indication).

2. Main Starting Signal - [ Red Lever]  controlling the starting signal immediately north of the cabin next to main line. This signal is used to indicate a clear road to north bound trains leaving the platform road at Mussel Pool; and as the call-on indicator for shunting operations from the main platform road onto the mainline via the northern point at Mussel Pool. MPMainstarter.jpg (78411 bytes)
3.Facing Point Lock and Bolt Lock - [ Blue Lever] controls the movement of the points lever [4]. All signal levers are interlocked with this lever as is the points lever itself. This lever locks the points when in normal position (releasing the signals) and releases the point lever ( and locking all signals at danger ) when reversed. MPPointBoltlock.jpg (115618 bytes)
4. Mussel Pool Northern Point Lever - [ Black Lever] controls the setting of the northern point. This lever is released by lever 3 in the reverse position, and locked by lever 3 in the normal position. MPNorthPoint.jpg (51655 bytes)
5. Main Inner Home Signal (Top Arm) - [ Red Lever] controls the approach signal ( adjacent to the northern point) and shunting call-on to Mussel Pool platform road from the main line via the northern points. MPHomeClrMain.jpg (81579 bytes)
6. Loop Inner Home ( Lower Arm) - [ Red Lever] controls the approach signal ( adjacent to the northern point) and shunting call-on to Mussel Pool Loop line from the main line via the northern points. MP Home.jpg (134959 bytes)
7. Outer Home and Distant (7a) - [ Red Lever] controls the operation of the Outer Home signal to give access to the Inner Home (splitting) signal at the approach to Mussel Pool.  MP Outer Home.jpg (69417 bytes)
7a. The Distant Signal [7a] is also attached to lever [7] and works in conjunction with the Outer Home giving an advance indication of the status of the Outer Home. Ie : 

Outer Home at Danger - Distant is at Danger. Outer Home at Clear - Distant is at Clear.

The mechanical interlocking under the floor of the cabin is a McKenzie and Holland No. 9 pattern interlocking machine.

This could be likened to a mechanical computer. The levers are interlocked by a series of rollers and cams that rotate as the lever is moved, to lock or unlock "T Bars" which are attached to the other levers thereby allowing appropriate levers to be moved, and locking inappropriate levers.
