    Mr Raven (my hero) said in 1911 that future locomotives would be heavier,go faster and therefore had to be three cylindered to avoid destruction of track,crew and locomotive.
    The Fowler proposal from 1924 for a three-cylinder compound had outside 570mm cylinders and that is possible because the cylinder spacing can be 1880mm due to conrods being inside coupling rods on first axle.Big drivers is no advantage for multicylindered locomotives and four times 15 tons is better than three times 20 tons.
    The best migthiest british passenger locomotive would have been a 4-8-0 with three compound cylinders and a wide firebox boiler over 1500 mm drivers.
    So simple in my opinion

    Several European countries used 4-8-0s with wide fireboxes. The Hungarian 424-class appears to have been the most numerous type.

    But I can find only one example of a 3-cylinder 4-8-0, namely the Soviet M-class (Russia's only 3-cylinder type?). Strange-looking machines, with bogie wheels of unequal size.
