7.3  Standard construction requirements for level crossings

ONTRACK, the predominant rail access provider in New Zealand, has developed geometric standards that it applies as appropriate to different types of level crossings, traffic levels and volumes. Other access providers may also have standards of their own. Non-specific geometric and operational standards around the rail lines include the following:

• The pavement must be sloped away from rail at a minimum of 1 in 50 for at least 5 m either side from centreline of the railway line.
• Surface water from the adjacent roadways must not be allowed to run onto the railway lines. All runoff must be collected prior to the level crossing.
• New or reconstructed level crossings require significant disturbance and, due to high train axle loadings, require time to settle after initial construction. Level crossings generally will not be sealed the day of construction for this reason.
• Chip seal is acceptable only as a temporary surface while a highly trafficked level crossing is being allowed to settle.
• Where retained asphalt or timber are utilised, the timber members must be installed 10 mm above the top of the rail to protect it from impacts from heavy axle vehicles.
• Where pedestrian mazes are provided as part of a new or existing level crossing, the specific geometry requirements noted in section 8 should be followed. Exceptions due to property restraint or other reasons will require rail access provider approval.
• Alternative level crossing material to asphalt or timber complying with rail access provider standards may be used, eg rubber slabs, subject to the approval of the rail access provider and road controlling authority.
