    I know you have the Book on Webb's Three-cylinder compounds. Have a look at all the additional pipework in the smokebox which gets in the way of routine maintenance, such as tube replacement and even cleaning. Take the Midland Compounds with...

    'Best' is a word rather open to interpretation; you need to specify from which point of view they were 'Best'. As you say the Compounds had their weaknesses and the main one was size - or lack of it. They were more than big enough for the...

    I sort of the agree with the comment about keeping your dreams to yourself but there does seem to be a trend on this forum for passive aggressive attempts (from some quarters more than others!) to shut down comments such as yours. This is after...

    Sorry, but wrong way around. The Compound regulator was an ingenious bit of kit and allowed the unskilled driver to drive them effectively. At small openings live steam was fed to the two low pressure cylinders to allow starting, at the same time...

    I don't think that it was "special" as it was a commonly used arrangement in the U.S. but the downside was a 'weak' front end requiring the use of braces to the smokebox. With the use of continuous frames and separate cylinder castings on the...

    I'm reminded of Adams' trial of the Wordsell-von Borries system (a two cylinder compound) on one of his 4-4-0s. It worked OK, and saved a small amount of coal, but that was more than outweighed by the additional lubrication demands, such that it...

    Not so the second driving axle having to deal with offset torque and massive torsional stresses. Not a huge problem in a country like Britain sitting on massive reserves of cheap coal, so the building and maintenance costs became the dominant...

    If last week was "El Scorchio!" this week saw temperatures fall to more sensible values, throw in some periods of rain and it had become a very much more typical summer. "Flaming June" had gone, into July and the days are becoming shorter,...
