Like many logging companies, the C&NR bought small Mikados and saddle-tank Prairies. These were two of the latter, presumably preferred in certain settings for its shorter wheelbases.
124 essentially repeated the 120's design, but increased oil fuel capacity to 750 US gallons (2,839 litres). Weight on the drivers decreased slightly to 90,000 lb (40,823 kg) while total engine weight increased to 120,650 lb (54,726 kg).
When the C&NR went back to Baldwin for another saddle tank logging Prairie, they nearly doubled the size of the boiler and grate as well as the water supply in the tank. The boiler was still saturated and the cylinder volume increased by very little, so the power available to the engine wasn't much greater.
After 17 years with the C&NR, the 125 was sold to the Santa Maria Valley where it ran for another ten years before being scrapped in 1947.
Apparently deciding that going bigger with in its saddle-tank Prairies (Locobase 14315) didn't deliver the results they were hoping for, the C&NR revisited the smaller engines shown in Locobase 14314, but superheated them. It was a tidy installation in a boiler of the same diameter. At the cost of exactly half of the original number of small tubes, the 126 garnered a good superheater area for more effective power. The adhesion wheelbase and weight remained effectively unchanged, which allowed the 126 to operate in the same environment.
But the 126 served the Kerry Line and its successor, K P Timber. In 1932, two different lumber companies set fire to their slash piles (accumulated logging debris) to get rid of them. The first turned into the Tideport fire. The second, started by K-P Timber to meet the requirements of the Fire Protection Association, did not threaten a similar escape for about a week because of damp conditions. Then, according to the history cited above," it too got out of control and then joined with the Tideport fire."
The result was a definitive disaster. "While much of the fire occurred over already logged lands, it destroyed 23 of the 35 Kerry Line trestles--7 on the mainline and 16 on the spurs south of Buster Camp. Logging operations were halted for the balance of 1932 and many of the spurs, now cut off by burned trestles were abandoned." K-P limped along for another 5 years but closed in 1938.
126 eventually went to Crossett Western as their second #7. CW sold the 7 to Consolidated Timber, who sent it along to Todd Shipbuilding, which presumably operated the engine during the war years before scrapping it in 1947.
