Bangkok’s tram system ran between 1888 and 1968, marking an important phase in the city’s transport history. It was the second tram system introduced in Southeast Asia. In the early years, trams were pulled by horses along fixed rails, but after the introduction of electricity, they became electric-powered — a cutting-edge technology of the time. Trams quickly grew in popularity, and the network expanded to 11 lines. The first route, Bang Kho Laem Line, ran from San Lak Muang (City Pillar) along Charoen Krung Road to Thanon Tok, covering 9.2 km.

The tram system was a crucial part of Bangkok’s infrastructure, shifting travel from waterways to land and driving the construction of roads. It influenced the transformation of the urban landscape, fostering the development of shophouses, commercial areas, and the expansion of the city beyond Rattanakosin historic area.

After the Second World War, trams declined in popularity as buses became the preferred mode of transport. In 1960, the government began phasing out tram lines, with the final service — the Circular City Wall Line — ceasing operations on 30 September 1968. This line circled the old city, passing Maharaj Road, Phra Athit Road, Mahachai Road, and Chakraphet Road.
