- The level crossing panels, support and fastening elements shall be designed to withstand snow and ice removal operations.
- Any metal parts in the level crossing system shall be protected against corrosion where presence of salt from the road traffic in winter conditions are taken into account.
2.3 Track construction
2.3.1 Track systems
Level crossing systems shall be designed to accommodate the following track systems:
- 60E1 rails on JBV 60 concrete sleepers in ballasted track with 60 cm (c-c) sleeper distance. Pandrol FC or FE fastening system

2.3.3 Flangeways
- Level crossings shall be designed to provide a clearance to the running rail for train wheel flanges.
- Level crossings shall have a horizontal flangeway clearance in the range of 60 - 75 mm.
- The depth of the flangeway clearance shall be minimum 40 mm.
- Pedestrian level crossings shall be fitted with a flexible flangeway gap filler for closing the flangeway gap. The flangeway gap filler shall be designed to be depressed by passing train wheels.
