In public transit, a limited-stop bus, tram, or train service is a service that stops less frequently than local service. The term is normally used on routes with a mixture of fast and slow services, and can differ in meaning, depending on how it is used by different transit agencies. Additionally, there may be a "semi-fast" service, with more stops than a "fast" service, but fewer than a "slow" service.
In a typical metropolitan area, limited-stop services are most likely to be scheduled at times when more people are travelling (these times are not limited to the rush hours).
Sometimes a higher (premium) fare may be required for the faster journey, especially for some international trains in western Europe.
On railways, the layout of the tracks and number/length of platforms at stations will normally limit the extent to which a blend of fast/semi-fast/slow services can be operated.
In Australia, particularly in Brisbane and Sydney, limited stop services are formed by commuter trains which run as limited stops or express services from the city centre to the edge of the suburban area and then as all stops in the interurban area. Same is done in Helsinki, Finland by VR commuter rail.
In the United Kingdom, some railway stations have tracks where there are no platforms, allowing more fast trains to rush past those stations without stopping. They may go down the middle of the station, or down the side. Examples are at Forest Hill, Raynes Park, Kentish Town and Totnes (the middle track at Totnes is only used in summer, by Great Western Railway services between London Paddington and Newquay).
Traditionally, a limited stop bus service usually operates on a route identical or similar to one or more local bus routes. They only serve certain bus stops, skipping others that local routes serve. Typically, the stops that are served by limited stop routes are chosen so there is even spacing stops and also that transfer points, major intersections, and popular destinations are served.
