Railway data - Slope

Railway tracks in Sweden generally have a gradient of less than 10 per thousand in order to be able to run heavy goods trains. Tracks where only passenger traffic is operated may have a higher gradient. The length of a track section with an even inclination shall be at least 20 m. See further reference [101]. Incline is included as a trace element in the description of the track geometry and is part of the profile geometry, which also includes vertical curves. Track geometry represents the design geometry and refers to the centre of the track. The data product contains the slope expressed in per thousand, the length of the track part that has the current slope and the method used for the data capture. Since the geometry has the attribute Origin = G (Geodetic), the data is coordinate-determined and comes from the GAD system or is transmitted from the Geosecma system. The data product is of high quality and can be used for all types of applications. The data product has stretch distribution and connects to the network with reference to the nearest previous node and the nearest previous kilometre board with distance in metres to both the start and end position of the inclination distance (=key points) in the direction of the track link.
