  1. No. Uneven steam distribution wasn't uncommon. Even if the valves were evenly set for both ends of the cylinder, which they rarely were, especially for a tender engine expected to normally work chimney first, there were other factors such as the reduced piston area of the back of the cylinder caused by the presence of the piston rod and angularity due to the slight forward position of the piston when the connecting rods and crank were at a true ninety degrees.
  2. Yes, there was one set of instruments per cylinder. The rollers at Rugby (and Swindon) measured performance at the wheel rim, not in the cylinders, so if you wanted to know what you were getting out of those, the indicator was the only way.
  3. The measuring process wasn't continuous and triggered only when the people inside the shelters pushed the appropriate buttons.
  4. You aren't alone. David. I do a lot of writing for various society magazines. I proof read them four or five times and send them when I'm confident all the errors have been eliminated. Then the magazine arrives in print, and there's always at least one!
  5. According to an F.J. Roche drawing, 7'3"+8'3"+5'9".That's all I have.
  6. Not an answer to the question but thought this looked interesting.
  7. When working opens, there was a difference between loaded and empty. The empties were obviously lighter so acceleration and braking were more rapid. But once you got them moving the empties were slower. As another guard put, 'The wind gets into the wagons and slows them down.' In practice, empties have two front faces moving through the air while loaded have only one. And yes, you could feel the difference.
  8. You certainly wouldn't want to be doing 107 mph on a Standard Five anywhere. They were hardly the best riding of engines, even when compared with the Stanier version, which could be lively, to say the least.
