498.022 OLOMOUC TO UNICOV.

498.022 SEPTEMBER 25, 2010

September 25, 2010. 498.022 was a star performer at the Olomouc National Rail Day. She then double headed the service train at 1050 from Olomouc to Unicov with 486.007. The photos below were taken.

The pre-war Pacific engines class 387.0 and 399.0 were successfully used in hauling of express trains on level lines, but for heavy trains in hilly areas their performance was not satisfactory. The Czechoslovak Railway Authority therefore placed with both Czech locomotive works (Skoda, CKD) an order for the three cylinder express locomotives with four coupled axles in 1932. Evaluation of both prototype versions (4-8-2 Skoda No. 486.001 and an alternative 2-8-4 CKD class 486.1 ) was in favor of the Skoda version. (The trial of these engines was in the Tatra mountains out of depot Spisska Nova Ves in Slovakia. Nine pieces of this 486.0 class were manufactured by both factories before 1938.

As a result of the need for postwar extension and restoration of the express train locomotive fleet the pre-war class 486.0 was chosen for further delivery. 40 pieces of class 486.0 locomotives numbers. 10 to 49 were ordered from Skoda locomotive works on October 6, 1945. The series was classified as Skoda 31Lo5 type with factory numbers 1706 to 1745. Many construction changes were introduced compared to the last pre-war engines (Nos. 486.008 and 009). Many of them concerned the material used - the use of more valuable materials was not possible in the post-war conditions, except for exceptional cases. The boiler was practically a new design, the cylinders were changed (the diameter was reduced from 550 to 500 mm), the whole design was reviewed. Also new tenders of class 935.0 were delivered for the new locomotives. The final design work was completed in the spring 1946. At that time the axle load was increased from 16 to 17,5 t, the maximum speed from 110 to 120 km/h. Due to these facts the locomotives were classified as class 498. Many parts are identical with the (not much later built) locomotives class 475.1. The boiler is nearly totally welded and its middle is at 3250 mm over the rails. The first work test of the completed locomotive, marked already as No. 498.001, was carried out on December 5, 1946. No. 498.002 was taken over by CSD as the first one on January 25, 1947. The first series (21 pieces) were manufactured by Skoda Works as 29Tr1 type with Nos. 894 till 914, for the rest an order was placed with CKD Prague Works, branch at Slany (Nos. 584 till 603). Total number of engines built: 40.

Some deficiencies found to exist in operation, led to various improvements. Among the most important were the mechanical stoker, the Kylchap type double exhaust nozzle (after cooperation with Chapelon from France), the Hulson type shaking grate. This improved their power from 1830 horsepower maximum to 2200 HP. All engines were reconstructed from 1951. 498.024 got type Witte smoke screens. Number 23 and 35 to 40 got larger smoke screens like type 475.1. During their final main overhaul in 1964 to 1965, a thermosiphon was installed in some engines.

The locomotive got the nickname "Albatros". Each engine rode between 1,8 and 2,3 million kilometers (except 498.019 and 024 which were withdrawn from circulation following accidents in 1952 and 1957).

The design of the new locomotives was a real surprise for both railway staff and passengers. The colors used (blue, red and white) symbolized the Czechoslovak flag. This color design can also be found on the No. 498.022 museum locomotive, which is in workable condition and used to haul special trains. It is stationed in Praha Liben.

Their first assignment were heavy express trains between Praha and Ceska Trebova. They were tested between Chocen and Pardubice with up to 136 km/h speed. Then, they were distributed to Praha Stred, Prerov and Bratislawa. Upon electrification of major lines, they came to Zilina (Slowakian mountains) and Bohumin. During the 1950s, these engines hauled most heavy express trains out of Bratislava. From the late 40s until electrification, they hauled trains between Praha and Kosice, part of them being stationed to haul trains between Zilina and Spisska Nova Ves, in the difficult Slovakian mountain region. 498.030 - 033 were at Bratislava in 1963, hauling trains towards northeast, together with engines class 498.1.From the late fifties (other sources sday 1961), they were also stationed at Plzen to haul trains on the lines Cheb-Plzen-Praha and from 1964 in Tabor and Ceske Budejovice to haul trains between Ceske Budejovice and Praha (For example number 040 in 1968). From 1965 they were also in Decin, hauling expresses between Praha and Decin (for example engines 032 and 034 in 1968).

At Plzen, these engines were also responsible for the express trains towards Praha until September 1968. Because of problems with train heating using diesel, locomotives 498.002, 011 and 016 ran again from November 1968 to January 1969. The engines also pulled the international express trains from Plzen to Furth im Wald (Germany) until 1972.

The first engine to be withdrawn was 498.019, after a head on crash in 1952 with 555.112. The next one was 498.024, equipped with Witte smoke screens, after a head on crash at Chozen with 414.412, in 1957. The remaining 38 engines had to cover a 28 days plan. From 1963, they only had 24 days. In 1969, the plan in Bratislawa went down to zero, the locomotives class 498.1 covering the remaining services. But 498.010 was still in steam on Jan 8, 1970. The last depot they went to was Leopoldov in Slovakia. On 31 December 1969, still 27 engines were rostered. Their last services were between Decin and Praha, where they during 1971 were replaced by diesels class T478.3, and the last four engines quit in Plzen in 1972. Decin had serviceable machines until 1974, however no plan.

Administratively they were withdrawn in 1976.

498.001 and 022 survived last. 498.014 from depot Plzen was stationary boiler from 1973 to 1976 and then went to the National Technical museum in Praha. 498.022 is preserved serviceable and stationed in Praha Liben. Its running days can be found here.
