Rail systems with specific construction issues operating on a segregated guideway (e.g. monorail, rack railways) are also treated as Metros as long as they are designated as part of the urban public transport network. Note 2 to entry: Adapted from CEN-CENELEC Guide 26. 3.3 tram UGT system not segregated from general road and pedestrian traffic, which shares its right of way with general road and/or pedestrian traffic and is therefore embedded in its relevant national road traffic legislation (highway codes and specific adaptations) BS EN 15153-4 pdf download.
