A proceed aspect is usually the green aspect shown on signals. In some signals, especially shunting and other special purpose signals, another colour may be the proceed aspect.

Track circuit territory

Used in track-circuited territory to ensure that the current of the track circuit can pass along from one rail to another. Obviously, a bond is not needed if the rails are welded together.

Bonding usually consists of a small gauge wire that is connected to the rail web via channel pins.

Electrified territory

Where traction return currents are along a track-circuited rail, a Rail Head Bond is used, which is larger diameter wire and often welded to the rail head.

Complex bonding arrangements may be required over points for both track circuits and traction return currents.

A rail corridor is the narrow section of land on which rail track(s) exist. It usually refers to to sections between cities i.e. the Melbourne-Sydney corridor.

A statement that describes what a candidate has done (project by project or at each project milestone) in terms of meeting the required performance criteria.

The more the rail episode is in dot points — that match dot points of the performance criteria — the easier it is for the assessor to be objective.

The modern rail has a cross section similar to as shown.

Either the owner or the franchisee who operates the railway.

Because of the large costs in developing and operating a railway, the owner of the railway is typically a government or high net-worth business.

The owner may separate the railway into above rail and below rail businesses, either or both of which can be franchised or self-run.

Rail points (switches in the USA), also known as a set of points or a turnout, is a track construction that provides a divergence or convergence of two routes.

A train approaching from A is able to diverge in two possible destinations, B or C, depending on the set of the points.

A train approaching from either B or C will converge into the only possible destination, A.

Railways operate in a variety of terrains and environments. There are a number of engineering methods deployed to assist successful train operation in these environments.

Trains prefer operating on flat or level surfaces as they have a maximum grade at which they can climb or descend. Train tracks are commonly sited on top of ballast to allow rainwater (and minor flooding) to drain away without affecting track alignment. ballast is also a particular shape to lock together and prevent rail and sleeper movement. The ballast may be on an embankment which is a raised level across mildly undulating terrain or low-lying wet areas.

Where faced with a hill, the route designers may choose (in ascending cost) to go gently around it, dig a culvert (ditch) or tunnel though it to maintain track within the maximum grade. In some major cities, entire systems are in tunnels.

Where faced with a valley, the route designers may choose (in ascending cost) to gently go around it, cut and fill the tops of peaks into the gully, build a bridge it or construct a viaduct. In some major cities, entire systems run on viaducts above roadways. 

Provides a context for the unit of competency, describing essential operating conditions that may be present with training and assessment, depending on the work situation, the needs of the candidate, accessibility of the item, and local industry and regional contexts. As applicable, the meanings of key terms used in the performance criteria will also be explained in the range statement.

Recognition of Current Competencies

RCC is an assessment process that assesses the individual's on-the-job and life experiences to determine the extent to which that individual has achieved the required learning outcomes, competency outcomes, or standards for entry to, and/or partial or total completion of, a qualification.

Tends to be used interchangeably with Recognition of Prior learning.
