AD60 Australian Steam Locomotive
History
This was the only type of Garratt locomotive to operate on the New South Wales Government Railways. Designed to a light axle load of only 16 long tons (16.3 t; 17.9 short tons), they were intended for hauling feeder branch-line services to the main lines where heavier main-line locomotives could continue with the load.
In 1949, twenty-five were ordered from Beyer, Peacock & Company, followed by a further twenty-five. Following a change of policy in favour of diesel traction, negotiations were entered into, in order to cancel the last part of the order. Forty-two complete locomotives were delivered, together with spare parts equating to approximately five further locomotives. The five sets of parts did not include engine unit frames. The cancellation contract stipulated that the NSWGR could not assemble the spare parts into complete locomotives without paying substantial royalties to Beyer-Peacock. The last three locomotives were cancelled completely and the assembly positions at the Gorton Works of Beyer-Peacock were sold to the South African Railways.
The locomotives were delivered in their five major component pieces: Front engine, rear engine, boiler-cab, rear bunker and front water tank. These five sub assemblies were built into a complete locomotive in NSW.
Locomotive 6002 was the first to enter service in July 1952 with the last, 6040 delivered on 2 January 1957.
The locomotives were the most powerful to operate in Australia but behind the D57 in terms of tractive effort.

6043 includes parts from multiple generations of AD60 garratt's making her a unique locomotive among them.
including things such as: mechanical stoker, extended coal bunker, and sound tubes from leading wheels to cab.
she was intended for heavy hauling freight as a single, or double headed locomotive.

Firing
firing a steam locomotive is likely something most people have not experienced. so here is a basic break down on how to fire this locomotive.
Step 1: below the firebox door there is a small lever, called the damper. open the damper to the max. this allows airflow into the bottom of the firebox.
Step 2: Open the firebox door, and at the far back of the firebox you will notice a small gauge. this shows your coal level inside the firebox. hold the button below the firebox door "shovel coal" until the gauge shows about 50%.
Step 3: once you have airflow, and coal entering the firebox. hold the "Ignite fire" button next to the "shovel coal" button for 2 seconds. and wait 60-120 seconds as the firebox begins to heat the water.
Step 4: Once you begin gaining boiler pressure. you'll notice in the sight glasses above the firebox door that your water level is going to rapid drop. to prevent this, move to the firemans seat (right)and directly infront of you will be 3 buttons. First press "water tank" which will open the water tanks. and then "Injector Increase" which will force water into the boiler to keep your water level up. (recommended injector level: 70-80%)
Step 5: To save you having to constantly checking the fire, the fireman also has "stoker" controls. which will fill the firebox full of coal constantly. to enable, simple turn on both, "Stoker steam injectors", and "Stoker Screw" buttons.
Congratulations. you have now successfully fired the AD60.
driving
Driving a steam locomotive is much simpler than firing. however there is still a lot to it. so here is a simple breakdown.
Step 1: ensure you have steam pressure. the AD60's saftey valve releases at 200psi. so 170-200psi is recommended for freight trains.
Step 2: now you want to choose your direction. this is done via the screw reverse directly infront of the drivers seat (left). for forwards, move the screw reverse to the right, and for reverse, move it to the left.
Step 3: release the brakes. you have 3 brakes. Train brake, Independent brake, and handbrake. the train and independent brakes are set to OFF automatically. but the handbrake, located behind the driver, is set to ON. however you might notice you still are not moving if you have a train behind you. this is because you require the "air compressor", located above the firebox in the centre of the cab to release the train brakes on other cars.
Step 4: pull the throttle and away you go. as you pick up speed, you can move the reverser bar closer to centre which will increase your maximum speed (ik thats not how it works for those who are picky)
Congratulations. you're now driving a steam locomotive.
quick apology
for those who have come from the stormworks discord server, I have posted about 3 months ago, that I would upload it for the 200 year celebrations. however I had some issues irl and couldnt finish it till now. sorry.
