NSWGR ballast crushing plant, steam driven

NSWGR ballast crushing plant, steam driven

A plant used to crush quarried hard stone to a size suitable for use as railway ballast. The plant cannot store output, so the crusher runs only when loading output directly to railway wagons via a chute.
The industry process consumes coal in a stationary steam boiler that powers a crushing engine that 'consumes' quarry stone to produce ballast.
Drivable tip trucks loaded with stone and coal may unload into the bins that have access points on the top level of the plant. Trucks are assumed to tip to the rear and therefore must back onto the unloading platform.
The sequential loading of open rail wagons is by gravity feed. Loading is one wagon at a time at the rate of 100000 litres (45 tonnes) per hour.
The grade on the asset's fixed track is 1 in 100, and a similar grade should be given to the flexible track attached to either side of the fixed track. The empty wagons are pushed by locomotive to the high end of the siding.
In the real world, shunters would uncouple several empty wagons at a time, gravitate them down to the loading point, load these wagons, then gravitate them to the low end of the siding. Repeat this procedure until all wagons are loaded.
In Trainz, the asset script detects the empty wagons, uncouples a rake of up to 4 wagons at a time, releases the hand brakes on the rake so that it falls towards the plant loading chute, then stops each wagon in a rake under the chute. Once a rake is loaded, the brakes are again released so that it gravitates to the low end of the silo siding.
A naming convention must be followed to establish a relationship between track marks and junctions used to find and set paths during the script-controlled loading operation.
There can be up to 4 'Empty' sidings upgrade from the silo and 4 'Full' sidings downgrade from the silo. The Empty sidings are collectively referred to as the 'Empty nest'. Similarly, the Full sidings are referred to as the 'Full nest'.
At the downgrade end of each siding there must be a track mark facing upgrade. These are named to identify the plant, the nest and the switching path required to access the siding from the plant loading bay.
Please read the document 'readme.txt' included with this asset to obtain details of the naming convention applying to the crushing plant, the junctions and track marks.
