Total engine weight ranged from 316,000 lb to 326,500 lb. Baldwin built 5 more in 1926.
It wasn't too long before the Central changed the boiler's layout from its original arrangement of 198 2 1/4" tubes and added 61 sq ft of syphons to the firebox heating surface. Somehow the superheater later gained 64 sq ft of heating surface without changing the number, diameter, or length of flues. The increase from 902 sq ft might have represented a recalculation rather than any actual changes.
These Mountains ran the CofGa mainlines pulling trains from the Midwest to Florida. Retirements began in 1948 and ended in 1953.
