Class Details by Steve Llanso of Sweat House Media

Class IIIe/326 (Locobase 1560)

Data from To be built in such numbers and wind up on three or four national railway systems is evidence, says A[nthony] E[dward] Durrant, The steam loc, "of a thoroughly sound design."

has a full history of this class, which entered service as the Class IIIe. Most eventually were refitted with an extended ("American") smokebox. Power demands meant that the class faded into obsolescence even before 1900. They moved into branchline service and many carried on until the 1970s.

After World War I caused the breakup of the Austro-Hungarian Empire, large batches of these engines were shared among several Southeastern European national railroads. 195 went to Romania's CFR, 110 to the SHS of Yugoslavia, 6 to CSD of Czechoslovakia, 5 to Italy's FS, and 3 to the Polish PKP.


Class IIIq/325 (Locobase 1559)

A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot, Devonshire: David & Charles, 1966), pp. 29, 40; "M-V IIIq" in Wikipedia at [link], last accessed 4 October 2022; and Skice I Glavni Podatci Lokomotiva (Zagreb: Zelieznicko Transporno Poduzece, 1955), p. 53. Works numbers were 459-463, 528-542, 566-570 in 1893; 925 in 1896, 1181-1189 in 1897; 1205-1209, 1230-1285 in 1898; 1375-1396 in 1899; 1400-1401, 1443, 1446-1448, 1502-1526 in 1900; 1595-1600 in 1901, 1601-1620 in 1902, 1663-1677, 1705-1720 in 1903; 1721-1724, 1776-1780, 1789-1795 in 1904; 1796-1800 in 1905, 1904 in 1906, 1905-1923 in 1907.

Termed by the MAV as Class IIIq in the 1890s, this inside-frame successor to the outside-framed Class IIIe (later class 326) followed the trend to compounding and offered a more powerful boiler as well. Exemplifying the Continental willingness to pull passenger traffic behind locomotives with no auxiliary axles, these engines worked the Fiume traffic, the Segesvar-Brasso-Predeal line, and the level sections between Budapest and Zimony (aka Zemun). On the latter service, these 6-couples pulled both traffic and freight. P[eter] M[ichael] Kalla-Bishop, Hungarian notes that they were delivered in three major batches between 1893 and 1907.

Of the 247 left in Hungarian service in 1918, reparations committees doled out 102 to the CFR in Romania, 68 to Yugoslavia, 9 to the Czech State, and 3 to Poland's PKP.


Class Type 106 (Locobase 20121)

This wood-burning member of the MAV's narrow gauge lineup could be prodced for any one of five gauge widths: 600, 700, 760, 900, and 1,000. Tiny in appearance, able to generate 50 hp and negotiate 24-metre curve radii,, the 75's permitted speed only reached 25 kph (15.5 mph).

Class V/374 (Locobase 1566)

Data from P[eter] M[ichael] Kalla-Bishop, Hungarian Railways (New York: Drake Publishers, 1973), pp. 85, Appendix 2. Works numbers were 1009-1010, 1056-1058, 1099 in 1870; 1435-1438, 1482 in 1872; 1483, 1490-1495. Original road numbers were 35-36, 49-51, 54-55, 73-75, 99-100, 130-144. Road 201-204 (

Branch-line freight engines built to a light axle loading for the Gyongyos and Eger branches. Kalla-Bishop described them as scaled-down 335s. The design remained in production until 1898.


Class Va/370 (Locobase 1565)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and [link] . See also P[eter] M[ichael] Kalla-Bishop, Hungarian Locomotives (NY: Drake Publishers, 1973).

Kalla-Bishop explains that these were a "miniature version" of the very successful two-cylinder compound 325s designed to run on much more lightly built branch lines.

Total evporative heating surface area used the tubes' external diameter in the calculation.

Originally known as the Va class and operated on secondary lines.


Class XII/ 377 / 310.4 (Locobase 13285)

Designed by Zsigmond Kordina and used in secondary freight and passenger service as well as on switching duties. These von Borries compounds had their scissor-like Stephenson eccentrics outside, mounted on the Hall crank bosses on the driving axle. Locobase 1571 shows the later engines in this large class; the principal difference was a slightly larger firebox.

Class XII/ 377 / 310.5 (Locobase 1571)

See A[nthony] E[dward] Durrant, The steam loc, P[eter] M[ichael] Kalla-Bishop, Hungarian , and [link]

Designed by Zsigmond Kordina and used in secondary freight and passenger service as well as on switching duties. This entry shows the last 305, which had slightly larger fireboxes; see Locobase 13285 for the first 219.

These von Borries compounds had their scissor-like Stephenson eccentrics outside, mounted on the Hall crank bosses on the driving axle.

After the breakup of the Austro-Hungarian empire in 1918, the 488 Type XII then in service were scattered to several countries. While Hungary retained 205, Poland received 2, Italy 12, the new Czechoslovakia 53, and Romania 123.
