Between 1929 and 1931, the Rotterdam Electric Tram purchased a total of 170 four-axle electric
motor cars. Until the 1960s, these trams were the backbone of the Rotterdam tram company.
Many cars have been given a museum destination, also at the Electric Museum Tramline Amsterdam and
the Tramline Dutch Open Air Museum in Arnhem. The 507 stays in Amsterdam, the 520, 535 and 536 in Arnhem.
