|Chicago Rock Island & Pacific locomotive #5000 pulling up to the Birmingham depot to receive his train orders in
1948. The train is heading west on the Burlington tracks which at times was normal. After 1950 they exclusively
used the #3 and #4 tracks through Birmingham, which were shared with the Chicago Milwaukee & St. Paul.

Birmingham on the Chicago Milwaukee & St Paul tracks (#4). This particular locomotive was the result of the
prototype locomotive #5000 shown in the previous post. Photo taken in 1948.
|The Milwaukee Shops of the Chicago, Milwaukee, St. Paul & Pacific Railroad built the first "Mikado" type
locomotives used on the railroad. The shops built twenty of them in 1909. These locomotives were designated as
Class L-1 and numbered 8500 through 8519. They had 63" diameter drivers, 24" x 30" cylinders, a 200 psi
boiler pressure and they exerted 46,630 pounds of tractive effort and each weighed 260,500 pounds. The
firebox was 282 square feet and the evaporative heating surface was 3,614 square feet. The L-1's did not have
a superheater. In 1912 and 1913, the shops built forty more 2-8-2's. This group was designated as Class L-2 and
assigned numbers 8000 through 8039. They were similar to the Class L-1 "Mikados" except the cylinder
diameter was 26 inches, which raised the tractive effort to 54,725 pounds. During 1912 the CMStP had the
American Locomotive Company build 115 of the Class L-2 locomotives and assigned them road numbers 8040
through 8154 and in 1914, ordered another twenty-five from ALCO, which were delivered the same year and
given road numbers 8155 through 8179. The class L-2 locomotives had 63" diameter drivers, 26" x 30"
cylinders, a 200 psi boiler pressure and they exerted 54,725 pounds of tractive effort and each weighed
275,000 pounds. The firebox was 258 square feet and the evaporative heating surface was 3,050 square feet
and with the superheater the combined heating surface was 3,690 square feet..
In 1918 and 1919, the USRA assigned 100 USRA "Mikado-Heavy" type locomotives to the CMStP. This was in
fact 43% of this type of locomotive assigned by the USRA. These locomotives were assigned road numbers
8600 through 8699 and were designated as Class L-3. The Class L-3 locomotives had 63" diameter drivers, 27"
x 32" cylinders, a 190 psi boiler pressure and they exerted 59,800 pounds of tractive effort and each weighed
325,000 pounds. The USRA "Mikado-Heavy" Class L-3 locomotives did well on the CMStP, but after the War,
200 more "Mikados" were ordered from the Baldwin Locomotive Works. These locomotives were very close
copies of the Class L-2. Baldwin delivered 100 between 1920 and 1921 and they were assigned road numbers
8200 through 8299 and Baldwin delivered another 100 between 1922 and 1923 and these were given numbers
8300 through 8399, later numbers 400-499.
Locobase had detected a relative insufficiency in superheater heating surface area compared to many other
Mikados of the period and apparently so did the Milwaukee some 90 years earlier. The last L-2's they procured
came from Baldwin (as had the L-2a shown in Locobase 15196), but these had boiler changes aimed at remedying
that shortcoming. Like all of the Milwaukee's L-2's, this class of -b's satisfied Milwaukee Road requirements
for decades and all operated into the 1950s. The Class L-2 road numbers 8300-8399, later numbers 400-499
were scrapped between January 1950 and January 1956.
There are no surviving Milwaukee Road 2-8-2 "Mikado" type locomotives.
Pictured above is a Chicago Milwaukee & St Paul locomotive #453, 2-8-2 Mikado, Class L-2b, local freight
heading westbound through Birmingham on the #4 track. This particular locomotive was built by Baldwin.
