On-street running or street running is the routing of a railroad track or tramway track running directly along public streets, without any grade separation. The rails are embedded in the roadway, and the train shares the street with pedestrians and automobile traffic. Street running trains generally travel at reduced speed for safety reasons.
Stations 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 board or disembark directly among mixed traffic in mid-pavement, rather than at curbside.
Freight trains using the infrastructure of Rhein-Sieg-Verkehrsgesellschaft to the company Evonik in Niederkassel-Lülsdorf passing the village Sieglar (next to Troisdorf) are running inside the Pastor-Böhm-Straße.
A section of service track of the H8/H9 BHÉV lines on Kerepesi Road in Budapest was rebuilt as street running in order to allow metro replacement buses to use the path to avoid traffic jams. The railway is only used by maintenance trains, mainly at night. Buses also only operate occasionally.
The only operational road-railway bridge in Hungary where street running happens is at Kisköre on the Tisza. Here, the non-electrified single-track railway carrying the branch line 102 of MÁV runs on the same path as local car traffic. The bridge is closed for road vehicles when trains pass.

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
Japanese law distinguishes between tramways and railways, but light rail does not exist as a separate category. For instance, the Toyama Light Rail line - with extensive street trackage - is legally a railway but uses low-floor light rail vehicles. Only operations with 'heavy rail' vehicles are listed here.
Examples under the jurisdiction of Japan's Railway Law include:
Keifuku Electric Railroad (Like the above Keihan lines, Keifuku uses high-profile railway-style vehicles and only includes short sections of street trackage; however the entire network is classified as a tramway.)
Fukui Railway (Operated as a single line, formerly with heavy rail stock, but street running section is legally a tramway.)
Nagoya Railroad's 600V network in Gifu (Abandoned in 2005, this network of street tramways inter-operated with interurban lines - such as the Minomachi, Tagami, Ibi and Tanigumi lines - that were classified as railways and used large, high-floor vehicles. The Minomachi and Tagami lines included short sections of street trackage classified as tramways.)
Niigata Kotsu Railway Line (This interurban line, abandoned in 1999, included a short street running section - legally a tramway - near its Niigata terminus.)
In Aguas Calientes, the town at the foot of Machu Picchu, the railway shares the streets with pedestrians, as well as in other towns further up the line. This railway serves as the only way of reaching Machu Picchu from Cusco without walking.
Av. Emídio Navarro with Ramal da Lousã track, in Coimbra, Portugal (2007)
In Coimbra, an 800 m single-track segment of Ramal da Lousã runs along Emídio Navarro, immediately southeast of the Coimbra-City station; closed “provisionally” in 2004, track scheduled to be lifted upon total closure of the spur line from Coimbra-B.[g]
In Lisbon a series of short single track segments along Avenue Brasília / Avenue Índia in riverside southwest Lisbon, links Linha de Cintura with Linha de Cascais and with cargo tracks associated with the harbour. It carries freight traffic only, mostly at night.[h]
In 1999, Žeželj Bridge, a railway and road bridge in Novi Sad (with separated traffic) was destroyed during NATO bombing of Yugoslavia. As a temporary replacement, a street running Road-Railway Bridge was constructed in 2000. It remained actively used up to 2018, when the new Žeželj Bridge opened, and the dismantling of the temporary bridge becan in October that year.
The Alaska Railroad bridge over the Chena River, located on Fort Wainwright, was previously shared by rail and road traffic. The U.S. Army eventually installed a new road bridge at a crossing downriver from the rail bridge and rerouted the roads accordingly.
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 controversial and the city tried to have them removed for decades. However, a short section along B Street from Ninth Street to Twelfth Street remains in active use.
Providence and Worcester Railroad Service to the northernmost piers of the Port of Providence and numerous sidings via Allens Ave. from the Harbor Branch. Tracks in situ, currently classed as "Out of Service" by FRA rules.
Division Street (WC, this section the Wisconsin Central mainline ran down Division Street along people's front yards, considered a bottleneck, the tracks were abandoned in 1996, and were removed later. Trains now run down Broad Street a few blocks east. The track there is owned currently by CN)
