Hungarian State 0-6-0 Locomotives in Hungary


Class Details by Steve Llanso of Sweat House Media

Class III/335 (Locobase 1563)

See A[nthony] E[dward] Durrant, The steam locomotives of Eastern Europe (Abbot Newton: David & Charles, 1966) , P[eter] M[ichael] Kalla-Bishop, Hungarian and [link]; and "MAV III" in Wikipedia at , [link], last accessed 11 July 2023.

233 produced Sigl in Wiener-Neustadt plus 18 in Budapest. Wikipedia's entry (Google translation) noted:Hungarian private railways also had this series. These included the Arad-Temesvár railway, First Hungarian-Galician Railway (Elso Magyar-Gácsoszági Vasút, EMGV, Hungarian Eastern Railway (Magyar Keleti Vasút, MKV), Hungarian Northeast Railway (Magyar Eszakkeleti Vasút, MEKV), Hungarian Western Railway (Magyar Nyugoti Vasút, MNyV).

These 18 were the first locomotives to be built in Hungary. Engine 269 was preserved and its photo shows the low-mounted cylinders, tall capped stack, steam dome set well forward and shorter sand dome just behind it, outside frame with springs mounted over each axle. Maximum speed was 30 mph (45 kph).

335,095 was preserved and restored. See it in motion in 2021 at [link].


Class unknown (Locobase 6940)

Data from Titre Exposition universelle internationale de 1878 a Paris. Rapports du jury internationale..Volume Groupe VI - Classe 64.
