1952
As a further development of Class 498.0 steam locomotives, 15x
units from this series are built between 1952 and 1954.
These three-cylinder locomotives had the same running gear and an axle load of 18.6 metric tons. They sparkled with their welded, high-performance boilers with a combustion chamber and a steel firebox with a high level of performance and attractive cost effectiveness. They were able to haul 600 metric ton trains on level terrain at 116 km/h and on a grade of 1.4% at 30 km/h. The modern standards for these units included mechanical stokers, the Kylchap dual blast pipe, a Škoda design multiple safety valve, a water purifier installed in the front dome, as well as SKF side rod and drive rod bearings. Witte smoke deflectors completed the sleek good looks. The completely enclosed cab contributed considerably to the comfort of the locomotive crew in the winter.

1960
While these locomotives were initially stationed at Prag, Přerov,
and Žiliny, starting in 1960, they were all assigned to Bratislava.
This did not change until 1970, when electrification provided new
areas of use. The class 498.1 locomotives now ran in operation out
of Nové Zámky and Plzeň (Pilsen). Road number 498 106 was even
equipped in 1978 with an HU unit in order to replace the
trouble-plagued class 753 diesel locomotives between Brünn (Brno)
and Přerov. It survived together with road numbers 498 101 and 108
in Pilsen until 1980 and then it was all over.
1964
August 27
The defined maximum speed of 120 km/h was sufficient for the hilly
routes of the ČSD, but clearly higher speeds could be reached. Road
number 498 106 demonstrated this quite clearly on August 27, 1964
in test runs on the experimental ring at Velim with a maximum speed
of 162 km/h / 101 mph.
1980
All units are removed from regular service by 1980.
One single "Albatros" remained in Slovakia: the operational museum locomotive, road number 498.104. At the end of 2004, this unit traditionally based in Bratislava had to be put into storage with boiler damage. There were several years of restoration with considerable support from the Albatros Club in Bratislava. Since the beginning of 2006, this locomotive has been on loan to the Albatros Club. The club is responsible for its maintenance and also for its operation and the locomotive crew. The restoration was completed in November of 2009. Since then, this mighty express train locomotive has gleamed again in the original paint scheme with the boiler, cylinders, cab, tender, and smoke deflectors in steel blue, the running gear in addition to the buffer beam in red as well as a continuous white stripe from the running boards across the cab to the tender. The roof of the cab is also carried out in white.
