Class Details by Steve Llanso of Sweat House Media

Class 514.1 (Locobase 1671)

Data from [link], last accessed 15 October 2020.

The first nine of this ten-coupled tank engine design were intended for the private Ferdinands-Nordbahn's MShrisch Ostrau - Dombrau section where they hauled coal trains. They were sufficiently satisfactory to prompt the CSD to purchase three more in 1930.

The FN was nationalized in 1945. Wikipedia says that two more were ordered in 1947 by the Stauding-Stramberger Eisenbahn ; StStD were similar . They were given 514.901-902. After further nationalization in 1951, the 901 was added to class 514.0.

Three more were completed in 1950 with some changes; see Locobase 1675.

All 514s were withdrawn by 1967.


Class 525.0/EP 1000 (Locobase 1675)

Data from [link], last accessed 15 October 2020.. AE Durrant, Locomotives of Eastern Europe. Works numbers were 2535-2537 in 1950.

20 years and World War II after the CSD took delivery of twelve 514.0 all-adhesion decapod tank locomotives (Locobase 1571), the CSD's successor ordered three more. Significant changes included 7,750 kg 17,086 lb) more weight on the drivers, a 1-bar (atm) increase in boiler pressure, more coal in the bunker, 2" (50 mm) taller drivers, 14.3 sq m (154.9 sq ft) decrease in tube heating surface area, and slightly less superheater area. (Cutting the tube length a modest amount might have been the reason for the decreases.)

Photographs show a burly profile with long, low tanks flanking the boiler. Three equal-sized domes--sand domes ahead and behind the steam dome- and a short stack occupied the front top half of the boiler. On the level, the 525s hauled 500 tons at 50 kph (31 mph). Scaling a 0.25% grade reduced both the trailing tonnage (300 tons) and the speed 14 kph (8.7 mph).

VftkovickT Pelezárny (Witkowitz Iron Works) ordered two more 525.0s.

All were withdrawn by 1967. The only 525 to survive to enter museum service suffered an accident on 29 March 2019 in Veself nad Moravou, when it was left unattended, ran away, and derailed. Although the locomotive remained upright, damage costs were estimated at 100,000 Czech crowns with another 50,00 to be spent on track repair.

The source's evaporative heating surface area calculations used the external (water side) area of the tubes. Fire side (internal diameter) would been lower by about 8-10%.
