#1351 was built by Alco as SLSF Consolidation type (2-8-0)
Class 1306 #1313 in 1912, but was converted to a Mikado type
(2-8-2) at the Frisco's shops in West Springfield, MO, in 1945. It was one of seven SLSF Consolidations converted to Class 1350 Mikados by the railroad between 1943 and 1946 (#1350-#1356). When #1356 rolled out of Springfield in 1946, locomotive construction on the Frisco ended.
It is hard to fathom but, despite an almost 30% increase in overall weight from 414,100 lbs to 530,100 lbs (226,400 lbs to 225,600 lbs on the drivers), the new Mikado delivered the same tractive effort (53,355 lbs) as the original Consolidation and, like #1313, this coal burner has a 50.3 sq ft grate, 26" x 30" cylinders and 63" drivers. It also operated at a boiler pressure of 195 psi but has a 350 sq ft firebox as opposed to 238.3 sq ft, and total heating surface of 4,083 sq ft including 835 sq ft superheating as opposed to 3,679 sq ft with 624 sq ft superheating.
The original 1306s were assigned to freight runs on Frisco's Eastern Division, from Springfield to Monett, MO, as well as the Southern Division, Springfield to Thayer, MO.
