A lingering demise
Few M-4s left the roster before 1929,
but depression and newer power led to
many of the class being scrapped in the
1930s. World War II brought a stay of
execution, as the SP needed every loco-
motive that could turn a wheel. Scrap-
pings resumed after the war, and by
1950 there were only 18 M-4s on the SP
roster, and only 23 still serving the
T &NO. All but two of the Pacific Lines
engines were gone by 1954, as were the
last T&NO engines a year later. Number
1673 was donated to Tucson, Ariz., for
display in 1955, and Gene Autry pur-
chased no. 1629 in 195 7. That engine
was placed on display in Saugus, Calif.,
in 1981. With over a half-century's ser-
vice from almost a third of the number
built, the M-4s repaid the Southern Paci-
fic's long faith in the 2-6-0 Mogul type.
