Perhaps we should present some data on the locomotives of our doubleheader.
Our lead engine is a Y6 number 2176 and the road engine is number 1230.
Both class A and Y6 were articulated, that is, the front set of cylinders and drivers is pivoted so as to swing on curves, in common with most other four-cylinder steam engines.
This effect may be seen at several points in the film at crossovers and switches.
The class A engines had larger drivers, a 2-6-6-4 wheel setup and were largely used on fast freight service.
At a distance the Y6 had a profile very similar to that of the A.
In fact, I believe the boiler was essentially the same, however, the Y6 had a 2-8-8-2 wheel arrangement and was one of the few true Mallet compounds in successful use on U.S railroads.
It was a comparatively slow-speed giant with tremendous pulling ability under all operating conditions.
The versatility of the Y6 was due mainly to the fact that it could be operated in simple as well as in compound.
In addition when working in compound, which was generally used at road speed, a booster effect was obtained by admitting high-pressure steam directly into the low-pressure cylinders of the front engine.
This gave added power at the lower speeds and had a startling effect on the exhaust as the individual beats were lost in an almost continuous roar.
Generally speaking, the Y6 tackled the load in simple using high-pressure steam in all four cylinders.
As the load was brought up to about 10 miles an hour the engineer would shift to compound, wherein the rear high-pressure cylinder exhaust was directed to the front cylinders to be reused.
However, in case the load forced a drop in speed back to 10 miles an hour or so, the booster would be cut in.
We might safely say that the Y6 was actually a three speed steam engine.

Description
The 16mm films presented here are the life's work of Edwin Carrington Eddy or Carrington Eddy as he preferred to be called as he traveled the globe and especially his interest in steam operated railroads. The presentation of these films would not be possible without the permission of the E.C. Eddy family and most importantly the Jenner Family Film Trust for which I will forever be indebted to their kindness for allowing the viewing of these films.
