I've been reading an interesting article by Frolin Marek about the Uintah Railway in the Winter 1994 LGB Telegram Vol. 5, No. 4 page 10.
While reading it two questions came to mind.
Frolin mentioned that due to the water leaving the crown sheet dry on a 7 1/2% grade, they added a 2nd steam dome (and lowered the crown sheet) to address the problem.
Apparently I do not know what a steam dome does because I have no idea how a 2nd steam dome would help. Can anyone tell me how it worked to reduce the problem?
My second question is about the coal supply of the Uintah 2-6-6-2.
The loco has huge water tanks on both sides of the boiler yet the coal supply behind the cab seems (to me anyway) to be far too small for the size of the loco.
Am I missing something? Why so much water and so little coal?
Thanks,
Jerry
