I downloaded the PDF - very interesting. California is not even mentioned,
and Washington state shows an 80% decline from 1918 to the late 1940's - down
to 899,000 tons or less than fifty 50 ton carloads a day. Utah shows 7 times
as much, and Colorado 5 times as much, as Washington.

Price patterns are interesting too. From 1940 to 1944 coal prices increased
over 50% !! And continued to rise after the war, with railroad fuel coal prices
doubled from 1940 to 1950. No wonder they dieselized!

Information on work days lost to strikes is remarkable - an AVERAGE of over
40,000 lost days of work PER DAY, EVERY DAY in 1949 - almost 1/10 of the entire
coal mining labor force. Even as mechanization reduced the number of jobs in a
steady pattern that continues to this day.
