Throughout the world, there are four examples of cross-border tram lines bridging the divide between communities of different countries.
To the best of my knowledge, the tram networks listed below are the only cross-border tram routes in existence. If you know of any more, anywhere in the world, please contact me.
Basel Tramway Network in Switzerland
Trams on The Basel Tramway Network (Basler Strassenbahn-Netz) are operated by two companies, Baselland Transport AG (BLT) and Basler Verkehrs-Betriebe (BVB).
An unusual feature of the network is that two lines terminate in towns outside Switzerland. Line No. 8 terminates at Weil am Rhein Bahnhof in Germany, and Line No. 3 terminates at Saint-Louis Gare in France. Line No. 10 crosses the Swiss-French border and has one stop in Leymen, France. The line then crosses back into Switzerland and terminates at Rodersdorf.
As far as I know, the Basel Tramway Network is the world’s only tri-national tramway system.

The Saarbahn Tramway System in Germany

Cross-border tram between Belgium and the Netherlands – This tram never arrived
A tram connection between Hasselt in Belgium to Maastricht in the Netherlands had been a project under discussion for over 20 years. However, in 2022, the Flemish government cancelled the scheme.

Note: In the USA, trams are called trolleys.
Since 2022 there have been news reports that the Blue Line trolley route from San Diego, USA, could be extended to connect directly with Tijuana in Mexico. Currently, the Blue Line from San Diego terminates at San Ysidro on the USA side of the border with Mexico. From San Ysidro, it is a 1 mile (approx 1.7 km) walk to Tijuana.

Cross-border tram lines in Europe that no longer exist
1. Find out about the history of pre World War II cross-border tram lines and transit trams in the Upper Silesia areas of Germany and Poland. (Internal link).
2. Find out about the tramway system in Teschen, Austria-Hungary, which opened in 1911. The service continued to run on a cross-border basis between Cieszyn, Poland and Těšín, Czechoslovakia, until 1921. (Internal link).
Cross Border Tram Lines – Opening-up International Borders
The above examples of existing cross-border tram lines perfectly demonstrate the will to open up international borders, as opposed to building barriers between communities.
