The network did, indeed, expand in the early 1920s, with the first night route launched in 1921, and lines creeping across Warsaw. By 1925, an official guide to the city’s tram network showed trams ran on most tram lines every five to 10 minutes. A single regular ticket was recorded as costing 15gr. The most expensive option was an unnamed (not personal) quarterly ticket, at the price of 78.75zł.
Still, one issue was connections to the suburbs. In 1927, a private line called Elektryczne Koleje Dojazdowe (EKD, or Electric Commuter Rail), was established, the first standard-gauge electric railway in Poland, owned by an electrotechnical and power industry company. Although similar to trams – and borrowing organisational charts from the city’s tram system – the EKD line was, in certain cases, incompatible with Warsaw trams, many of which used a wider gauge. The route travelled from Warsaw to Grodzisk Mazowiecki, west of the city.
The line was particularly known for its use of novel technology, boasting modern traffic light systems imported from Sweden, and carriages imported from England. A guide to the line in 1929 praised its connections to the outskirts of the city, away from ‘the hectic heartbeat of metropolitan life’. Ten years later, it was running every 10 minutes during rush hour.
The city’s tram network were was also linked to other transport proposals in the Interwar period too; notably, plans to build a metro line, which were suggested in the mid-1920s. In 1929, the Underground Railway Department was established at the Construction Office of the City Trams Directorate, responsible for the construction of the underground – but work was paused after the Great Depression.
