Leipziger Parkeisenbahn, miniature railway in Leipzig, Germany

The Leipziger Parkeisenbahn is a 381 mm minimum-gauge railway that runs on a 1.9-kilometre loop around Auensee lake in the Wahren district of Leipzig. Its trains are hauled by the steam locomotive 03 002, built in 1925 by Krauss & Comp., and by an electric battery locomotive converted in 1995 from a 1958 diesel locomotive of the Waldeisenbahn Muskau. The line has eight passenger coaches built in 1988, each with 16 seats, plus a goods wagon that supplies compressed air and electricity to the steam train.

The first sod for the loop around Auensee was cut in October 1950, and Leipzig's Pioniereisenbahn opened on 5 August 1951 as the second 381 mm children's railway in the GDR, after Dresden. It began with four carriages and a steam locomotive supplied by Erich Brangsch GmbH of Leipzig-Engelsdorf. Flooding halted operations for five weeks in summer 1954; since 1990 it has run as the Parkeisenbahn Leipzig.

The railway is a place where young people take on real responsibilities in train operations. Visitors see children and teenagers working as conductors, station staff, and ticket sellers, which gives the place its distinctive character.

The 1.9 km loop around Auensee has stops along the shoreline where passengers can board and alight. Trains are pulled either by the steam locomotive 03 002 or by the battery-electric locomotive converted in 1995. The eight passenger coaches built in 1988 each seat 16 people.

The steam locomotive 03 002 was built in 1925 by Krauss & Comp. (works number 8352) and appeared at exhibitions in Munich, Düsseldorf and Cologne before being stored in a quarry near Kamenz during the Second World War. It has run on the Auensee circuit since August 1951 and was restyled to resemble a Class 03 locomotive in 1965.
