I love it, Howard ! Spot on ! I got caught like this recently, the cabinboy had the answer !
Dante Porta had the answers to many poorly running steam engines, and David Wardale proved some of them. For practical purposes steam is a gas, so to work properly it needs to be gas flowed. What s the point of lots of steam if it can t get to the cylinders when needed ? Putting pressure gauges on the steam chests (9F) was quite a revelation, it showed the driver what was REALLY happening. You put exhaust gas temp gauges on a big diesel ! Noel.
Yes, Noel!
