The diesel locomotives of the SJ Z4 (XIII) series were bought by the Swedish State Railways Statens Järnvägar (SJ) in 1953 to replace steam locomotives in shunting and light handover services. The small locomotives were used at railway stations and in workshops in railway depots.

With this series, the 13th design variant of two-axle small locomotives of the Z4 series of the SJ was added.

prehistory

In the Z series , SJ sorted a large number of different small locomotives. In the 1940s and 1950s, the state railways began to further subdivide small locomotives into performance groups. Group Z3 , with an output of 90 to 110 kW, was in the middle of the groups formed.

Rail vehicles from different manufacturers and with different looks were classified into this group, but they all corresponded to the same performance level. This group includes locomotives from Bjurström AB Slipmaterial from Västervik and ten locomotives supplied by Kockums in Malmö between 1937 and 1939, each with a driver's cab at both ends, as well as machines built by Kalmar Verkstad that were initially included in the Zsh series , But then they were sorted into performance group Z3 . With the nationalization of many private railway companies, there were more individual pieces that were classified under this series.

SJ Z4 (XIII)

In 1953, Klöckner-Humboldt-Deutz delivered a series of small locomotives that looked similar to the much more powerful V20 of the Deutsche Bundesbahn and the Z6 (VIII) locomotives of the SJ. These had a diesel-hydraulic change gear of the Voith L33yU type . Just three years later, the ten locomotives were rearranged under the series under SJ Z42 .

It was actually planned to order a larger number of these locomotives. It turned out, however, that the SJ Z6 (VIII) delivered by Deutz at the same time could be used much more comprehensively. That is why it was decided very quickly to only use these small locomotives in the depots and no further procurement was made.

SJ Z42

In 1956, the ten small locomotives supplied by Klöckner-Humboldt-Deutz were re-designated as the new Z42 277–286 series while retaining their running company numbers .

SJ Z3 (IX)

In 1958, the division of small locomotives according to performance groups described at the beginning was refined again. The ten locomotives that were given the series designation SJ Z3 (IX) were renamed again. The running company numbers were retained.

At the beginning of the 1970s, the locomotives were shunted in Hagalund , Boden , Vilhelmina , Vännäs , Sundsvall , Östersund and Halmstad . The Z3 285 was scrapped in Vislanda in 1979 as the first machine, followed in 1983 in Örebro by the Z3 283, which had already been parked in 1978 .

Railway service vehicles

Eight locomotives were added to SJ's rail service vehicles in 1981 . They received new numbers with the series designation Qaz . This series designation changed again in 1986 to Qzb . The following table shows the redrawing and the further whereabouts:

In 2018 the Z3 280 was still available at Norrbotten's Järnvägsmuseum (Malmbanans Vänner) in Karlsvik .
