Texas & Pacific class B-6
United States 1902 7 produced
The class B-6 consisted of seven 0-6-0 switchers built by ALCO-Cooke for the Texas & Pacific. Their numbers were 317 to 323. They were introduced with a boiler pressure of 200 psi that was reduced to 175 psi in 1916. Three were equipped for oil burning in 1916 and 1917, so the six tons of coal in the tender were replaced by 1,600 gallons of oil. At the same time, the T&P built 28 0-6-0 switchers of the class B-5 in their own works.
