West Point Railroad

The Atlanta & West Point Railroad and the Western Railway of Alabama were affiliated with the Georgia Railroad and were known as the West Point Route. The A&WP got its first "Mikado" type locomotives in 1918, which were built by the Lima Locomotive Works. They were designated as Class F and assigned road numbers 400 and 401 and were copies of the Georgia Railroad's 2-8-2s numbers 300-302. Theses locomotives had 63" diameter drivers, 27" x 30" cylinders, a 185 psi boiler pressure, exerted 54,575 pounds of tractive effort and each weighed 280,000 pounds.

Three more Lima-built 2-8-2s were added to the A&WP roster between 1923 and 1925. These three locomotives were copies of the Georgia Railroad number 320 and were designated as Class F and numbered 425 through 427. They had 63" diameter drivers, 26" x 30" cylinders, a 200 psi boiler pressure, exerted 54,700 pounds of tractive effort and each weighed 292,000 pounds.

A final "Mikado" came from the Baldwin Locomotive Works in 1944. This Class F locomotive was given road number 430 and was a copy of the USRA-Heavy Mikado. The locomotive had 63" diameter drivers, 27" x 32" cylinders, a 190 psi boiler pressure, exerted 59,800 pounds of tractive effort and it weighed 325,000 pounds.

There are no surviving A&WP 2-8-2 "Mikado" type locomotives.

Georgia Railroad

The Georgia Railroad ran from Atlanta, 171 miles east to Augusta, GA where it connected to the Atlantic Coast Line to reach Wilmington and Charleston, thus increasing the value of Atlanta as a rail center. The Georgia Railroad also had a branch off its main from Augusta to Macon and Athens, GA.

The Georgia Railroad took delivery of its first three "Mikado" type locomotives from the Lima Locomotive Works in 1915, and these locomotives were designated as Class F63 and assigned road numbers 300 through 302. A fourth Class F63, 2-8-2 was delivered by Lima in 1918 and it was given number 303. This group had 63" diameter drivers, 27" x 30" cylinders, a 180 psi boiler pressure and exerted 53,200 pounds of tractive effort and each weighed 280,000 pounds. The firebox was 322 square feet, the evaporative heating surface was 4,336 square feet and with the superheater the combined heating surface was 5,495 square feet.

In 1923 and 1925, seven more Lima-built "Mikados" were delivered and they were assigned road numbers 320 through 326. These locomotives had 63" diameter drivers, 26" x 30" cylinders, a 200 psi boiler pressure, they exerted 54,700 pounds of tractive effort and each weighed 292,000 pounds. The firebox was 280 square feet, the evaporative heating surface was 3,777 square feet and with the superheater the combined heating surface was 4,957 square feet.

There were six other "Mikado" type locomotives on the Georgia Railroad. Two ALCO-built 2-8-2s were purchased from the CCC&StL in February 1937 and assigned road numbers 305 & 306. Four Baldwin-built 2-8-2s were bought from the Clinchfield in 1943 and they were given road numbers 331 through 324.

There is one surviving Georgia Railroad 2-8-2 "Mikado" type locomotives. It is number 302, on display at the Augusta Museum in Augusta, GA.

Western Railway of Alabama

The Western Railway of Alabama and the Atlanta & West Point Railroad were affiliated with the Georgia Railroad and together these two railroads were known as the "West Point Route". The first "Mikado" type locomotives received by these railroads came in 1918 from the Lima Locomotive Works. They were designated as Class F and assigned road numbers 350 and 351 on the WRA and road numbers 400 and 401 on the A&WP. These locomotives had 63" diameter drivers, 27" x 30" cylinders, a 185 psi boiler pressure and they exerted 54,575 pounds of tractive effort.

During 1923 and 1925, each of these railroads received more "Mikados". They were built by Lima and were similar to the first Class F locomotives of 1918. WRA received four and numbered them 375 through 378 and the A&WP received three and numbered them 425 through 427.

In 1944, the two railroads took delivery of one 2-8-2 each. The Baldwin Locomotive Works built these two locomotives. One went to the WRA and was assigned road number 380 and one went to the A&WP, which was given number 430. These locomotives had 63" diameter drivers, 27" x 32" cylinders, a 190 psi boiler pressure and they exerted 59,800 pounds of tractive effort.

There are no surviving Western Railway of Alabama 2-8-2 "Mikado" type locomotives.

Class Details by Steve Llanso of Sweat House Media

Class F (Locobase 7323)

Data from A & WP-WRA 11 - 1949 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 5002-5004 in January 1915, 5695 in July 1918.

These were Harriman Common Standard Mikados like those supplied to the other constituents of the West Point Route (Locobase 7320). Three of the four in this class preceded the other WPR engines; the fourth was delivered with the rest.

Sometime later in their careers, the class saw an update in its firebox. Two received thermic syphons that together with the arch tubes contributed 87 sq ft to 301 & 303's firebox heating surface. 300 & 302 received 60.3 sq ft of security circulators, which resulted in a commensurately lower amount of total heating surface.

In both forms, Georgia RR ran them until 1953-1954.


Class F (Locobase 9469)

Data from GA Steam Loco diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 6575-6579 in 1924 and 7006-7007 in 1925.

Although built in 1923, this Ohio-built quintet were virtually identical to the USRA's Light Mikado design; two more followed in 1925. Even though the count of superheater flues was identical, the Georgia Railroad gave the superheater area as 1,180 sq ft (109.6 sq m) . Delivered with 31 sq ft (2.9 sq m) of arch tubes, some were later refitted with 60 sq ft (50.75 sq m) of security circulators for a total firebox heating surface of 309 sq ft (28.7 sq m).


Class F (Locobase 7320)

Data from A & WP-WRA 11 - 1949 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 5691-5694 in July 1918.

According to Drury (1993), this batch of four locomotives were a continuation of the Harriman Common Standard Mikado. The lower-numbered pair went to the Atlanta & West Point, the higher-numbered duo to the Western Railway of Alabama. 350 received Nicholson thermic syphons, which increased its firebox heating surface to 285 sq ft (26.5 sq m).

Retirements came in 1951 (401), 1952 (351, 400) and 1954 (350).


Class F (Locobase 7321)

Data from A & WP-WRA 11 - 1949 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

These USRA Light-Pacific clones came into the WPR ins three batches for the three constituent railroads - the Atlanta & West Point (425-427), Western Railway of Alabama (375-378) and the Georgia Railroad (320-326); see Locobase 9469 for the Georgia RR locomotives.

By builders' numbers, the assignments were:

Builder Railway Road Number

6730 A & WP 425

6731-6732 WRA 375-376

6929 A & WP 426

6930 WRA 377

7004 A & WP 427

7005 WRA 378

Given the typical long life of WPR steam engines, it's not surprising to see that these all ran until 1952-1954.


Class F (Locobase 7322)

Data from A & WP-WRA 10 - 1945 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 70887-70888 in July 1944

Among the very last Mikados to be built new by an American manufacturer were this pair, which were distributed to the Atlanta & West Point (road #430) and Western Railway of Alabama (road #380) , respectively. As Drury (1993) notes, these were "...essentially updated USRA heavy 2-8-2s, a testimonial to the soundness of the 1918 USRA design."

They were near the top of the list in terms of weight, but about average for heating surface area. Although the diagram doesn't say so specifically, Locobase suspects the firebox had thermic syphons or security circulators and Drury's photo and caption details the Boxpok drivers, cast trailing truck, Elesco coil-type feedwater heater, and immense tender.

Because they arrived so late, these two Mikes only ran for a decade before being scrapped.
