KiwiRail's tunnels on the rail network, represented as a single polyline for each tunnel, which aligns with the track centreline (Main Left/Up Main only) from the start point to end point of the tunnel asset. Tunnels are identified with a combination of tunnel number and line name. Attribute information includes Lat and Lon coordinates (decimal degrees) for the midpoint of each polyline.This data is suitable for mapping but not for survey accurate information or exporting to CAD for design (does not include true track geometry/design or elevation).Supplied as ESRI Feature Service (polyline) in NZTM.
