Guide bar

Guide bars, or guiding bars[1] are rubber-tyred metro systems that incorporate 1,435 mm (4 ft 8+1⁄2 in) standard gauge track.

They have angle irons as outside of the two roll ways.

The Busan Subway Line 4 lacks a rail track, and has I-beams installed as guide bars.

The Sapporo Municipal Subway, that lacks a rail track as well, has no guide bars.
