The tram line built in Sitterfell near Berlin has been put into operation, which indicates that the tram has been put into use as a passenger vehicle.

2. The peak period of tram development

In the 1920s and 1930s, the world set off a golden age of rapid development and construction of trams.

1895, American tram lines reached 12 100 km. 1930, 70 cities in France * * * opened 3400 kilometers of operating lines. 1920, the total length of tram lines in Britain reached 5000 kilometers, and the number of tram vehicles reached 14400.

3. The decline of trams

After the Second World War, the rapid development of the automobile industry had a great impact on the tram industry.

4. The revival of trams

The tram system has been fully upgraded.

Adopt modern, large-capacity articulated vehicles, build separate tram lines, and use special signal control to build transfer hubs such as subways and buses. The upgraded tram is more similar to the rapid rail transit in terms of speed, reliability, comfort and safety than the traditional tram. Therefore, this relationship has been given a new term-modern tram, and it has been widely used in Europe and America and many developing China countries.

At present, many cities in the world have begun to rebuild or expand modern tram lines. As a new form of urban rail transit, modern trams have been widely popularized all over the world after the transformation from tradition to modernity.
