This metre-gauge local railway was completed by the Berlin-based Vering & Waechter construction company in 1903-1904. The four locomotives shown in the specs went into service at opening and operated on that line for decades and amassed over 850,000 kilometres in service by 1941. Through war and peace, these engines served the M & M until the 1960s.
