On-street running or street running is the routing of a railroad track or tramway track running directly along public streets, without any separation. The rails are embedded in the roadway pavement, and the train shares the street directly with pedestrians and automobile traffic. Trains generally travel at reduced speed for safety reasons.
If there are stations on the section, they can appear similar in style to a tram stop, but often lack platforms, pedestrian islands, or other amenities. Passengers may be required to wait on a distant sidewalk, and then to board or disembark directly among mixed traffic in mid-pavement, rather than at curbside.
Although bridges and tunnels are not streets, rails can still be embedded in the surface of bridges and tunnels like the Inuyama Bridge (Japan) or the Anton Anderson Memorial Tunnel (US). This is also considered to be "street running".
This list does not include conventional tram systems, which by definition run in the street.
- The North Coast main line runs down Denison Street in Rockhampton, Queensland carrying freight and passenger services.
- Mossman, Queensland. A sugar-cane railway runs down Mill Street.
- Wycheproof, Victoria has a seasonal freight-only mainline railway running along the centre of the main street.
- Gold Coast, Queensland has a tram called the G:link that runs along the Gold Coast Highway between Southport and Broadbeach and a large proportion of Nerang and Queen Streets until the tracks reach Griffith University.
- Wiener Lokalbahn – tram-train running on tram tracks in Vienna and Baden and as light rail between the two towns. A section of the light rail tracks in Guntramsdorf runs directly on the Feldgasse narrow street, but without any stops on it.
Notable examples in Canada include:
- The C-Train runs through 7 Avenue South, which only emergency and Calgary Transit vehicles may run on
- Clarence Street (From Nelson Street to Icomm Drive, Canadian National Railway, still in use)
- Louisa Street (From just east of Thomas Street to Catherine Street, Canadian National Railway, removed, continues to Welland Avenue below)
- Welland Avenue (From Francis Street to Balfour Street, removed)
- Caroline Street (from Erb Street West to Allen Street West, tracks removed in 1994)
The legal separation of a street running trackbed and an exclusive trackbed in urban traffic is given in § 16 BOStrab tramway regulations.
The MTR Light Rail running in and between the new towns of Tuen Mun, Yuen Long and Tin Shui Wai has many sections of on-street running, although many parts of it run on their own tracks alongside major roads or elevated, e.g., at the several junctions near Tuen Mun Town Centre.
One of the most famous locations is when the steam-powered Darjeeling Himalayan Railway "Toy train" squeezes between narrow shop fronts down past a bazaar in India.
Indonesia used to have an extensive "steam tramways" (more accurately defined as local railways) network, which had many street running sections in various towns and cities in Java and Sumatra.
Two sections remain in use in 2010: part of the Wonogiri branch runs along the Slamet Riyadi street in Surakarta, and a short branch to an oil depot in Madiun. The earlier line sees both passenger and freight service (including a steam-hauled tourist train), while the other line is exclusively for freight.
Freight trains to and from the docks at Dublin share the Alexandra road with cars
- Inuyama Bridge (The bridge on the Meitetsu Inuyama Line runs across the Kiso River. It is now exclusively used by trains in an effort to eliminate the previous bottleneck caused by roadway traffic.)
- Enoshima Electric Railway
- Kumamoto Electric Railway (A short section on the Fujisaki Line)
- Fukui Railway (Its street running section is registered as a tram line under law but full-sized trains from the rest of the network run directly onto the tram line)
- Keihan Keishin Line
- Keihan Ishiyama-Sakamoto Line (Both of these lines, which include short street-running track around the Hamaōtsu Station, are legally tram lines but use rather high-profile vehicles. Additionally, the Keishin Line has through services onto the Kyoto Subway Tozai Line.)
- Keifuku Electric Railroad (A short section on the Arashiyama Line. Like the above Keihan lines, the Arashiyama Line uses high-profile railway-style vehicles but is classified as a tram line.)
- Toyama Light Rail (This line, categorised as a railway under law, is converted from the Toyamakō railway Line and includes newly built street running sections)
- Niigata Kōtsu (This abandoned line consists of a short street running section near its Niigata terminus.)
In Aguas Calientes, the town at the foot of Macchu Picchu, the railway shares the streets with pedestrians, as well as in other towns further up the line. This railway serves as the only viable way of reaching Macchu Picchu from Cusco without walking.
Swiss law does not distinguish between trams and railways, making the distinction between street running by trams and that by railways subjective.
Maeklong Railway Market, Bangkok
The most notable track where street running was common was the Weymouth Harbour Tramway; however this has been out of service to regular traffic since 1987, and to all traffic since 1999.
There is a freight-only street-running railway network in Trafford Park; only one section along Barton Dock Road is still in regular use.

- From 1912 until April 2000, trains operated approximately 1.25 miles (2 km) down Ninth Street, one of the major arteries of the city. The tracks were built by the Tidewater Southern Railway and later operated by the Union Pacific. They were very controversial and the city tried to have them removed for decades. A short section along B Street from Ninth Street to Twelfth Street remains in active use, however
