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 guide flange (ridge) is on the inside to prevent the vehicle from slipping sideways off the rails. The horizontal (cone-shaped) rim makes contact with the slightly convex top of a steel rail in different (horizontal) places so that the outer wheel has a larger effective diameter than the inner wheel.
Plate rail was an early type of rail and had an 'L' cross-section in which the flange kept an unflanged wheel on the track. The flanged rail has seen a minor revival in the 1950s, as guide bars, with the Paris Métro (Rubber-tyred metro or French Métro sur pneus) and more recently as the Guided bus.

A roll way or running pad is the pad placed on a concrete slab or on the ties on the outside of the 1,435 mm (4 ft 8 + 1 ⁄ 2 in) conventional track along both running rails of a rubber-tyred metro or along the unconventional track of a tram. The rubber-tyred wheels roll directly on the roll ways. With a conventional track:
