UNDER UTARBEIDELSE

1 Scope

This specification applies to delivery of modular level crossing surface panel systems.

2 Functional requirements

2.1 Design loads

This specification applies to 4 different level crossing classes depending on the road traffic type:

• level crossings for freight terminals
• level crossings for normal traffic
• level crossings for light traffic
• pedestrian level crossings

2.1.1 Level crossings for freigth terminals

Level crossings for freight terminals shall be designed to carry min 1250 kN axle load.

2.1.2 Level crossings for normal traffic

Level crossings for normal traffic shall be designed for minimum road traffic loads according to Tabell 1:

Tabell 1: Design loads normal traffic

Axle configuration	Axle distance [mm]	Minimum design load, all axles [kN]
single axle	-	115
dual axle bogie	1300 - 1790	180
	1200 - 1290	160
	800 - 1190	150
triple axle bogie	1300 - 1790	240
	1000 - 1290	220
	< 1000	160

2.1.3 Level crossings for light traffic

Level crossings for light traffic shall be designed for minimum road traffic loads according to Tabell 2:

Tabell 2: Design loads light traffic

Axle configuration	Axle distance [mm]	Minimum design load, all axles [kN]
single axle	-	60
dual axle bogie	1200 - 1790	90
	800 - 1190	85
triple axle bogie	1000 - 1790	120
	< 1000	90

2.1.4 Pedestrian level crossings

Pedestrian level crossings shall be designed to carry load from pedestrians, bicycles and hand held trolleys.

2.2 Track construction

Level crossing systems shall be designed to accommodate the following track constructions:

• 60E1 rails on JBV 60 concrete sleepers in ballasted track with 60 cm (c-c) sleeper distance. Pandrol FC or FE fastening system
• 54E3 rails on JBV 54 concrete sleepers in ballasted track with 60 cm (c-c) sleeper distance. Pandrol FC, FE or e-clip fastening system
• 49E1 rails on JBV 54 concrete sleepers in ballasted track with 60 cm (c-c) sleeper distance. Pandrol FC, FE, e-clip or PR-clip fastening system
• 54E3 rails on Type_X wooden sleepers in ballasted track with 52 cm (c-c) sleeper distance. Pandrol e-clip or Hey-Back fastening system
• 49E1 rails on Type_X wooden sleepers in ballasted track with 60 - 65 cm (c-c) sleeper distance. Pandrol e-clip or Hey-Back fastening system
