SR Merchant Navy Class - Performance of The Rebuilt Locomotives

Performance of The Rebuilt Locomotives

There is no doubt that rebuilding the class solved most of the maintenance problems whilst retaining the good features, thereby creating excellent locomotives. However, as a result of the implementation of Walschaerts valve gear, the rebuilts were prone to hammerblow on the track caused by the additional weights incorporated to balance the outside valve gear, an issue that had not arisen with the self-balanced arrangement of the original locomotives. On 26 June 1967, 35003 Royal Mail recorded the highest speed ever for the class. Hauling a train comprising three carriages and two parcels vans (164 tons tare, 180 tons gross) between Weymouth and Waterloo, the mile between milepost 38 and milepost 37 (located between Winchfield and Fleet) was covered in 34 seconds, a speed of 105.88 mph. This was also the last authenticated speed in excess of 100 mph achieved by a steam locomotive in the United Kingdom.

Famous quotes containing the words performance of, performance, rebuilt and/or locomotives:

    Just as the performance of the vilest and most wicked deeds requires spirit and talent, so even the greatest demand a certain insensitivity which under other circumstances we would call stupidity.
    —G.C. (Georg Christoph)

    The way to go to the circus, however, is with someone who has seen perhaps one theatrical performance before in his life and that in the High School hall.... The scales of sophistication are struck from your eyes and you see in the circus a gathering of men and women who are able to do things as a matter of course which you couldn’t do if your life depended on it.
    Robert Benchley (1889–1945)

    The problem with marriage is that it ends every night after making love, and it must be rebuilt every morning before breakfast.
    —Gabriel García Márquez (b. 1928)

    The flower-fed buffaloes of the spring
    In the days of long ago,
    Ranged where the locomotives sing
    And the prairie flowers lie low:—
    Vachel Lindsay (1879–1931)
