The locomotive originally intended to become Plant System No. 119 was the 20,000th locomotive built by Baldwin. It was a 4-6-0 that incorporated several novel features. One was the balanced Vauclain compound system that had its high pressure cylinders mounted between the frames and not above the low pressure cylinders as usual. Inspired by the French De Glehn compounds, the high pressure cylinders drove the second set of drivers through a crank axle, while the low pressure cylinders drove the first set of drivers. The Vanderbilt boiler had a cylindrical firebox with annular corrugations that needed no staybolts. The tender was also of the Vanderbilt type with the characteristic cylindrical water tank.
After the locomotive was completed in 1902, the Plant System refused to take it over. Instead it was sold to the Chicago Short Line and became their No. 1. They only used it for a short time and sold it to the Ashland & Western, where it still carried the number 1. Its next change of owner took place only three years later when it became No. 686 of Southern Iron & Equipment. There are indications that it was equipped with a conventional firebox there. But selling it three times was not enough, and so it came to the Atlanta, Birmingham & Atlantic in 1912 where it again got the number 1. They scrapped it in 1920.
