See relevant RailCorp standards for definitions of other terms.

4 Functional Requirements Level crossings are installed to provide a safe track crossing, at grade, for road, pedestrian and stock traffic. Level crossings also provide access to the track for road/rail vehicles.

A safe crossing equates to the ability to:

− warn users (rail, road and pedestrian users) of the existence of a level crossing

− warn users of the approach of conflicting traffic with sufficient time for protective action to be taken

− allow for the passage of specified (size, weight and speed) road, rail and pedestrian traffic.



5 Design Requirements

5.1 General The design of level crossings shall be based on the requirements specified in this document.

Designs are to include:

− crossing structure suitable for the traffic loads

− provision of a flangeway for train wheels

− guard rails

− end restraints for panels

− skid resistant road surface

− slip resistant pedestrian surface

− provision for surface water to flow away from the crossing

− track drainage

− interface with the track structure

− interface with the track geometry

− reliable insulation so as not to interfere with track circuits for signaling, including for typical in-service situations e.g. tin cans in the flangeways

− lighting

− traffic control treatments.

The level crossing structure at a location shall be of consistent type and material. There should not be a mix of panels and full depth construction nor a mix of panel material type.

The design of control treatments at level crossings shall be based on AS1742.7 “Manual of uniform traffic control devices Part 7: Railway crossings” and the requirements specified in this document.

− turnouts and insulated joints.

In addition, passive control level crossings shall be located in accordance with the sight distance requirements detailed in this standard and clear of existing installations which restrict sight distance.

Level crossings should not be located on curves.

The location of a level crossing shall be reviewed by a competent track designer with respect to the track geometry. The track levels, superelevation and vertical grading of the track are important considerations in the design of the level crossing and the design of the interface between the track and the level crossing surface.

5.3 Design Loads Level crossing structure designs shall be based on the traffic using the crossing.



Road pavement level crossings shall be designed in accordance with Austroads publication AP-G17/04 “Pavement design – A Guide to the Structural Design of Road Pavements”.

Road modular level crossings shall be designed to carry the traffic loads as specified in AS 5100.2 ”Bridge design - Design loads”.

Track vehicle access crossings shall be designed for the range of vehicles using the crossing to access the track. The minimum design load shall be the R20 truck – see Appendix for details of R loading configuration. If heavy construction equipment is to use the crossing, the crossing shall be designed as a road level crossing.

Pedestrian level crossings shall be designed to carry pedestrian loads and, where relevant, traffic loads from vehicles travelling along the rail corridor which may drive over the crossing. The minimum load shall be the pedestrian loads in AS 5100.2. The minimum traffic load shall be the R20 truck.

In yards and sidings only, service pedestrian level crossings may be designed for the walkway loads in AS 1657 “Fixed platforms, walkways, stairways and ladders – Design, construction and installation”.

5.4 Flangeways Level crossings shall be designed to provide a clearance to the running rail for train wheel flanges.

Level crossings shall have a minimum flangeway clearance of 60 mm.

Pedestrian level crossings shall have a maximum flangeway clearance of 65 mm as new, maintained to 75 mm. The maximum depth of the flangeway clearance shall be 50 mm.

5.5 Guard Rails Guard rails shall be provided on level crossings:

− located on curves with radius less than 400 metres

− located on curves with radius wider than 400 metres which are subject to curve wear

− constructed with asphaltic concrete.

The length of the guard rails is to be the design width of the level crossing plus 600 mm for each tapered end (run-in) of the guard rail. The taper shall be 25 mm over the length of the run-in.

The top of the guard rail is to be level with the top of the running rail.

If the flangeway edges of level crossing panels are steel, tapered ends similar to guard rails shall be provided.

Guard rails are to be in accordance with the following standard drawings:

− CV 0388392 “Level crossing guard rail arrangement to suit 50 kg and 60 kg rail”

− CV 0169390 “Guard angles for asphaltic concrete type level crossings”.

For pedestrian level crossings, guard rails shall comply with standard drawing CV 0169390, as flangeway depth is limited to 50 mm in accordance with AS 1742.7.

5.6 Asphalt Level Crossings Asphalt for level crossings shall be designed and installed in accordance with AS 2150 “Hot mix asphalt – A guide to good practice”.

Road level crossings shall use an asphaltic concrete mix for heavy traffic wearing course applications.



Pedestrian level crossings shall use an asphaltic concrete mix for light traffic wearing course applications.

Service level crossings shall use an appropriate asphaltic concrete mix based on the traffic load on the crossing.

5.7 Modular Level Crossings 5.7.1 General

The level crossing structure shall consist of internal panels to span between the rails of an individual track and external panels for a distance not less than 580 mm outside each rail of that track.

Larger external panels may be designed to span the entire space between adjacent tracks.

The internal panels and the edge of external panels parallel to and adjacent to the rails may be supported either by the track structure or from the rails.

The edge of external panels parallel to and remote from the rails may be supported either by the pavement subgrade or an independent edge beam. Where an edge beam is not used, the road surface abutting the crossing shall be provided with an edge and support independent of the external panels to the level crossing surface system to enable removal of the external panel(s) without damage to the abutting road or footpath surfacing.

Panels shall be properly secured by end restraints.
