These locomotives had 64" diameter drivers, 29" x 32" cylinders, a 195 psi boiler pressure, they exerted 69,698 pounds of tractive effort and each weighed 395,000 pounds.
The Class L-1s were used between Chicago and St. Louis in freight service and pulled an average of 5,000 tons which was 1,500 tons more than the "Mikado" (2-8-2) pulled on the same lines. On one particular day an L-1 pulled a troop train of thirty cars at a speed of 35 mph.
During late 1941 and 1942 the Wabash sold eighteen of these locomotives to four other railroads. Six were sold to the KCS, five to the MoPac, five to the C&IM and the other two were sold to the C&EI. Of the remaining seven five of them were sold to the C&IM, two in 1947 and three in 1950. The other two were scrapped by the Wabash, numbers 2503 scrapped in 1950 and number 2507 scrapped in 1951.
There are no surviving Wabash 2-10-2 "Santa Fe" type locomotives.

Boiler was Extended Wagon Top (EWT). Although Railway Age credited the design with 1,129 sq ft of superheater in 1917, by 1929, the same flues were credited with the heating surface area as shown. Also the firebox heating surface area, given as 389 sq ft (36.1 sq m) in 1917, was reduced to the 361 sq ft; this included 47 sq ft (4.35 sq m) of arch tubes.
Used on the Decatur Division between St Louis and Chicago, pulling an average 5,000 tons (compared to the Mikado's 3,500 tons). The RG article noted a performance in which an L-1 pulled up to 30 passenger cars in a troop train at speeds of 35 mph.
Two eventually wound up on the C&O as class B-3 after passing through the Pere Marquette. They were the heaviest of the C&O's Santa Fes; they had the highest factor of adhesion and the largest boilers.
Most of the rest were withdrawn by the end of World War II and the remaining seven had been disposed of by 1950-1951.
Locobase 88 tells us about this class of big Santa Fes as they entered service in World War One. During decades of use, however, most classes of road engines in US service underwent some sort of upgrade and this entry is intended to show which pieces and parts were modified or added and to what effect.
The two locomotives represented by this entry had slightly different makeovers. 2515 received a Worthington 4-B-2 feedwater heater, which added 5,000 pounds to total engine weight. Both operated Duplex D1 stokers and both were equipped with Nicholson thermic syphons which contributed 79 sq ft to the firebox heating surface for the loss of 2 arch tubes. The remaining 3 arch tubes added 25 sq ft to the firebox heating surface. 2719 had received its syphons by 1928. Locobase is not sure which locomotives received the appliance or when.
By the end of World War II, only 7 remained in service; they were all withdrawn by 1951.
