Summary Sheet Blackwater Version 7.0 March 2017 System

General Information The Blackwater System is bi- Curragh, Boorgoon, Kinrola, Ensham, directional duplicated track with Gordonstone, Rolleston, Minerva and The Blackwater System is crossovers between Callemondah and Gregory with a spur line at Fairhill for Rocklands, between Rocklands and Yongala. Triple unloading balloons are located in Central Dingo, between Umolo to Walton and located at Golding, with unloading between the latitudes 23°8’ S between Bluff and Rangal, with the balloons at Stanwell Powerhouse, and 24°28’ S and longitudes remainder being single line. Fishermans Landing, Gladstone 148°5’ E and 151°15’ E. Powerhouse, Auckland Point, Because of changed traffic tasks Barney Point and Comalco. (), this system now incorporates The system primarily services coal the section of track from Burngrove to The Blackwater System is electrified mines off the Central Line and carries Nogoa to Minerva (previously part of by an autotransformer system with the the product through to Stanwell Power the Central West System). overhead line equipment operating at Station, Gladstone and 25 000 volts, 50 Hertz, alternating the Port of Gladstone via the North Loading balloon loops are located supply (25 kV, 50 Hz, ac).

Description of Asset Type Length / Total the Railway 1171.361 km (Includes yards, Total Track The track (1067 mm gauge) sidings & passing loops) on the main trunk route from Blackwater to Gladstone is Duplicated Track 296.950 km generally 60 kg/m rail with concrete sleepers. Passing Loops 27.298 km (16 Passing Loops)

Bridges allow the passage of Sidings 14.371 km (35 Sidings) 106 t (26.5 tal) wagons at 80 1122.527 km (Includes yards, Electrified Track km/h. Allowable axle loads and sidings & passing loops) speeds on branch lines vary as 979.895 km (Including Left described below. Access Roads and Right side of track) Based on the improved asset intelligence provided as a result of the Level Crossings 228 Crossings Network Asset Management System, the following new totals are provided Lubricators 40 Sites for this system. The linear data is accurate to sub-meter distances. Crew Change Facilities 87 Sites

Turnouts 447 Turnouts (Mainline & Yards) Overhead Line Equipment Distribution is via a contact wire The contact wire height may vary from suspended from a catenary wire and 4400 mm to 5850 mm above rail level. The Blackwater System is these two wires are held in place by supporting structures to maintain ideal Typically in the Blackwater System electrified by an utotransformer pantograph/contact wire interaction. the traction system uses both rails for system with the overhead line return current. equipment operating at 25 Typically, the autotransformer system also uses a 25 kV AC feeder wire run 000 volts, 50 Hertz, alternating on the back of the supporting structure supply (25 kV, 50 Hz, ac). which is used for voltage support throughout the electrified network.

The dual wire distribution system is automatically tensioned to maintain a constant wire tension and requires a pantograph uplift force of 80 N ± 10 N for smooth spark less current collection.

Operational Systems Following exceptions: and Train Control RCS and Rail Operator (RO) The Blackwater system is Gladstone Yard Controlled operated by Remote Control Signalling (RCS), with train Auckland Point Rail Operator (RO) Controlled movements controlled from . Barney Point and QAL Rail Operator (RO) Controlled

Callemondah - Gladstone Powerhouse and Callemondah - Golding are controlled from the Callemondah signal cabin.
