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:
  • The ones of the Montreal Metro are precast concrete on a concrete slab.
  • The ones of the Paris Métro are H-steel on ties.
  • The ones of the Mexico City Metro are H-steel.
  • The ones of the Santiago Metro are precast concrete below ground and H-steel above ground.
  • The ones of the Lausanne Métro Line M2 are H-steel.
  • The ones of the Lyon Metro (lines A, B and D) are H-steel.
• Without a conventional track:
  • The ones of the Lille Metro are precast concrete.
  • The ones of the Toulouse Metro are precast concrete.
  • The ones of the Sapporo Municipal Subway are flat steel with a central guide rail.
  • Busan Subway Line 4 runs directly on a concrete slab between guide bars.
  • Many people mover systems, such as Crystal Mover, run directly on concrete slabs or other surfaces between guide bars.
  • Some guided buses, rubber-tyred trams, such as Translohr and Bombardier Guided Light Transit, use concrete slabs while being guided by a single central rail.
