Bender says on page 159 that the crown sheet was lowered
as part of the Uintah's two-part solution in addition to the new
steam dome. He doesn't mention using two different throttles
so I assume the throttle box was re-located to the new dome..
The first run returning downgrade from Baxter Pass disclosed
low water in the water glass and the engineer quit. The ICC
boiler inspector in Grand Junction embargoed the engine until
repairs were made.
The trailing truck was also modified to prevent derailing when
backing,coal capacity increased & new air vents for cooling the
crew when backing.
The Uintah shop guys were pretty good.
