KkStB 88.28 (Krauss Linz 1236/1883), originally numbered 235. After 1918 this engine went to PKP and was withdrawn before 1927. Location and date unknown. Source: www.commons.wikimedia.org.

 

 

KkStB 88.52, the last example built (originally ordered by Österreichische Lokaleisenbahngesellschaft, Krauss Linz 1610/1885), was taken over by FS and served as 809.002 until August 1923. Source: as above.

In 1880 Austrian k.k. priviligierte Kaiserin Elisabeth-Bahn (KEB) took delivery of five class L light 0-2-0 tank locomotives for mixed traffic on secondary lines and switching, built by Wiener Neustadt. They were considered a successful design, enough to justify a much larger order for the state railways. Between 1882 and 1885 kkStB received 47 examples from Krauss Linz, initially classed S I. They were slightly heavier and differed in having larger boilers and cylinders increased in diameter from 250 to 280 mm, as well as in other minor details. Last three examples, originally ordered by Österreichische Lokaleisenbahngesellschaft and built in 1885, differed in boiler details. Later several engines of this type were fitted with modified boilers, with slightly reduced heating surface. In the kkStB service these locomotives were initially numbered from 213 upwards (KEB engines were numbered 208 through 212). In 1884 KEB was taken over by kkStB and later their class L locomotives became 8801 through 8805; those built against state orders were re-numbered 8806 through 8852. Two more similar engines were ordered by Böhmische Westbahn (BWB) from Krauss & Comp. of Munich as class S, factory type XLVc later kkStB 8871 and 8872. Within the framework of the new designation system, introduced in 1905, locomotives originally ordered by kkStB were classed 88, those from KEB – 188 and those from BWB – 288; service numbers – last two digits – were retained.

Between 1905 and 1917 twelve ‘proper’ class 88 locomotives were withdrawn. After the war nine were kept by Austrian state railways BBÖ; last survived in service until 1929. Czechoslovakian state railways ČSD took over seven examples, of which six were later classed 222.0 (88.30 was written off in 1923, still with old kkStB number, and cannibalized for spares). They were soon relegated to auxiliary duties or sold, but some enjoyed very long life: the last one, 222.005 (ex 88.25, Krauss Linz 1233/1883) was withdrawn in August 1946. One example went to the Kingdom of Serbs, Croatians and Slovenians; it was written off in 1930. Italian state railways FS took over four 88s, classed 809, but they saw little service and were withdrawn in early 1920s; at least one was sold to industry. Fourteen locomotives of this already obsolete type went to Poland and became the property of PKP. Most probably they remained in southern Poland. According to www.pospichal.net, class designation TKb13 was probably reserved for them; this is also confirmed by LP. If this was the case, it was never actually assigned, as all were withdrawn before 1927. No example of this type has survived until today.
