These four Lineside Data Sheets were released on 12th August, 2007;

B9 - Station Building Standard Design A5, c.1909

This design of station building was used at many locations on both main and branch lines. The sheet has been prepared from NSWR drawings for the standard station, and with reference to early photographs of the station buildings erected at Casino, Tumut and Gular.

The A5 design provided accommodation for a Ticket Office serving a General Waiting Room, with a separate Ladies Waiting Room and Lavatory. There was also a large Store with access to the platform and the road side, and an awning roof over a sheltered alcove off the platform, enclosed on three sides by the building. Water tanks were provided to the original design, though at many stations these were demolished in later years. There are many differences in the details of this design as constructed at various locations, particularly in the brackets supporting the awning roof and the gable details, and the design as constructed at some locations was mirrored.

The sheet shows the floor plan of the building, with both long side elevations and one end elevation and a section through the Waiting Room.

 

L13 - 9" Water Column for Electrified Areas, c.1927

This column was designed for watering steam locomotives at locations where overhead electrification had been installed. The underslung jib can pivot horizontally and vertically, but it's movement is limited to prevent it from coming into contact with the overhead wiring. A platform was constructed to give firemen easy access to the controls for the water supply and the swinging of the jib. The jib could be extended a short distance as required on a track mounted on the column. This extension and the elevation of the jib were effected by hand levers on the jib, while the swing of the jib was controlled by a hand wheel and gear running around a toothed segment. The design of the platform, drain and counter balance to the jib may have varied at different locations.

The sheet shows both side and both end elevations, and plans at ground level, platform level, jib level, and at the top of the column. The degree of movement permitted of the jib in swing, elevation and extension are shown.

An example of one of these columns has been restored by the NSW Rail Transport Museum at the Valley Heights Locomotive Depot, and I am grateful for the assistance given me by Ken Rudd during the preparation of this sheet.

 

L14 - 40' Turntable, c.1890

This sheet has been prepared from NSWR drawings for the turntable installed on the Lismore to Tweed railway, and with reference to photographs of the turntables at Lismore and Murwillumbah. However similar turntables were installed at other locations in the early years, where locomotives were expected to be accommodated within a length of only fourty feet!

This turntable was constructed from a pair of fabricated iron plate trusses with cast iron assemblies for the central pivot, the frames at each end, and the pivot mount which was fixed to a large concrete drum in the centre of the earthen floored well. The end frames supported a small platform on one side on which was mounted a locating lug and a handle that operated gears to one of the support wheels to facilitate rotating the table. The trusses carried two heavy timber beams to which the track was fixed, and between which timber decking was fitted. The support wheels ran on a circle of double head rail fixed to short sleepers sitting on a skirt and spoon drain around the inside of the well wall. It is interesting to note that at least some of the early examples were fitted with Barlow rail, presumeably recycled from the old Sydney to Parramatta Railway.

The sheet shows the plan of the table and well, a long section and elevation, a cross section of the table and elevations of the end of the table and the well wall at the track. It is reproduced at 1:43.5 scale (7mm:1'0"), so may readily be reduced to 50% to give 3.5mm:1'0" scale.

P16 - Level Crossing Boom Gates, c.1912 and 1922

This sheet illustrates two types of early boom gates used by the NSWR, and the gear used to operate them remotely. The 1912 gate is shown as a single boom across the carriageway, with a timber boom carrying a skirt of closely spaced vertical iron strips that swivel by gravity as the boom opens. The boom has a cast iron counterweight and pivot, and is mounted on timber posts set into the ground. The opening end of the gate rests on a timber post which has a catch to secure it in the closed position, remotely operated from a lever in an adjacent signal cabin. The arrangement of the pulleys, cables and standard McKenzie and Holland capstan operated gear mounted on the lever frame for working the gates from the signal cabin is also shown. Gates to this design were installed at Metford and Warwick Farm.

The 1922 design is shown as a double boom gate across a wider carriageway. The boom and support stand are fabricated from rivetted iron plate and angles and the gates have a skirt formed from more widely spaced members with horizontal bars as well, which is folded by levers as the gate opens. There is a central target disc in two halves, one on each gate at the opening end. When closed the gate is supported on the ground by a foot on the skirt and a short extension mounted on the top of one gate ensures the alignment of the gates in this position. Cast iron counterweights were fitted, moveable to correctly balance the gate for various sizes between 12' and 20' in 1' increments depending upon the width of the carriageway. Gates to this design were installed at Ryde, Villawood and Broadmeadow.

The sheet shows the plans, elevations, end elevations and various details of both types of gates, and elevations and details of the capstan operating gear in the signal cabin. I am indebted to Mick Nicholson of Hull, UK, who provided me with details of the standard McKenzie and Holland equipment.

 

Currently in prparation;

A number of sheets are currently being prepared and will become available as they are completed. I anticipate that the next sheets to be available will be

Please let me know if there are any sheets that you would particularly like to see, or if you have any material that may be of use in the preparation of any future sheets.
