Hungarian State Railways IIIe and Košice–Bohumín Railway IIIe
Hungarian State Railways class 326, Czechoslovak State Railways class 313.2, and Yugoslav State Railway class 125
The IIIe was a 0-6-0 freight locomotive designed by Sigl at Wiener Neustadt as a successor to the III. Starting in 1882, a total of 512 were built mostly for the MÁV, 15 of them for the KsOd and some for the GySEV. A total of six manufacturers came from Austria, Hungary and Germany. Some of the GySEV locomotives were rebuilds of the III.
These locomotives had outside frames, Hall cranks, outside cylinders and inside valve gear. They were rated for 598 tonnes at 45 km/h on the level and for 333 tonnes at 20 km/h on one percent inclines. Later batches got a new boiler and an extended smokebox.
From 1911, they became kkStB class 326. After World War I, 195 came to the CFR and 110 to the SHS railway. Both of these operators still designated them class 326. The ČSD received fifteen from the KsOd and called them class 313.2. Additionally, five went to Italy and three to Poland.
