Hey CN1,
That picture is an excellent example! From what I have read, if'n y'all are
interested, the Mallet (pronounced mall-AY) may be any type of
compound
articulated loco, not a particular wheel arrangement. The "compound"
refers to live steam being directed from the boiler to the fixed rear cylinders first;
the exhaust from the rear cylinders, still hot steam under pressure, is then
directed to the front cylinders, which are much larger in diameter, due to the
reduced pressure.
The front cylinders and drivers pivot at a point near the rear cylinders, thus
making the arrangement "articulated." CN1's photo clearly shows off the larger
front cylinders.
To confuse the issue, apparently some roads used "Mallet" indiscriminately
to identify some non-compound articulateds; this is technically incorrect.
For my own interest, I'm going to read a little more on the subject.
And Hi, BDC, good to see ya!!!! :thumb: :thumb: :thumb: Hope you're all
in one piece, did you say you were a Training Instructor? Been busy, I'll bet!!
Hey Topo, "he's off his rocker" is similar to "he's not playing with a full deck",
or "he has bats in his belfry!" Also, "he has lost his marbles", or "his elevator
doesn't go all the way to the top floor!" I'm sure there are more, you've heard
most of them here, I think!!
