Oc13

SiN 1511/1872 was built for MNyV and numbered 5. Later it became kkStB 19.05 and after the war was taken over by PKP. Most probably it was to have become Oc13-2. Source: www.commons.wikipedia.org.

MÁV 1039 (SiN 754/1869) was originally built for MEKV and numbered 2. After the war it was taken over by Romanian state railways CFR and withdrawn in 1925. Source: as above.

MNyV 7 (SiN 1590/1872), location and date unknown. Later MÁV 853, then 1030 and finally, since 1911, 238,030. After the war this engine went to Yugoslavia and was written off in 1930. Source: as above.

Hungarian state railways MÁV between 1869 and 1870 took delivery of fifteen class II passenger locomotives with the 1-2-0 axle arrangement from the Wiener Neustadt works of the Sigl company. Similar locomotives, differing only in details, were also built for several other private railways in Austria and Hungary; these included:

- Ungarische Nordostbahn (Magyar Északkeleti Vasút, MÉKV) – 21 examples between 1869 and 1873;

- Ungarische Ostbahn (Magyar Keleti Vasút, MKV) – 17 examples between 1870 and 1873;

- Ungarische Westbahn (Magyar Nyugoti Vasút, MNyV) – eight examples between 1870 and 1872;

- Erste Siebenbürgener Bahn (Első Erdélyi Vasút, EEV) – three examples in 1872;

- Lemberg-Czernowitz-Jassy Eisenbahn (LCJE) – four examples in 1873, all being given individual names;

- Kaschau-Oderberg Bahn (KsOd) – six examples in 1873;

- Győr–Sopron–Ebenfurti Vasút (GySEV) – four examples between 1874 and 1875;

- Erste Ungarisch-Galizische Eisenbahn (Első Magyar-Gácsországi Vasút, EMGV) – three examples in 1874 plus one more in 1885;

- Waagtalbahn (Vágvölgyi Vasút, VVV) – three examples between 1876 and 1877.

This gives the total of 85 locomotives. Many engines used by Hungarian private operators were taken over by MÁV after nationalization; state railways eventually had 58 examples in their inventory (some sources give 64). Later they were classed 238. After KsOd was taken over by Czechoslovakian state railways in February 1921, one engine was impressed into ČSD and later numbered 232.101.

Austrian kaiserlich-königliche Staatsbahnen (kkStB) took over three locomotives of this type from EMGV, four from MNyV and all four from LCJE; all were classed 19 and given consecutive service numbers. They were later fitted with modified boilers, adopted from late production class 23, steam pressure being increased from 8.5 to 10 bar. Typically they were coupled with three-axle class 40 tenders. Five of these obsolete engines were written off before 1918 and one was lost in Russia during the war. BBÖ kept only 19.06, but it was withdrawn in 1925. The remaining four – including three from MNyV and one from LCJE – were taken over by PKP. Some sources state that they were classed Oc13, but this has not been ultimately confirmed. In fact PKP had as many as seven types of ex-kkStB 1-2-0s and assignment of new class designations to individual types is still subject to dispute. In some cases data from various sources are contradictory. Be it as it was, this assignment was most probably only formal, as all locomotives of this type had been withdrawn until 1927. No example has been preserved.
