Guide bar
 | The lead section of this article may need to be rewritten. (June 2013) |
The rubber-tyred metro systems that incorporate 1,435 mm (4 ft 8+1⁄2 in) standard gauge track have angle irons as guide bars, or guiding bars, outside of the two roll ways. The Busan Subway Line 4, that lacks a rail track, has I-beams installed as guide bars. The flanges are vertical. The Sapporo Municipal Subway, that lacks a rail track as well, has no guide bars. It has a central guide rail instead.
