A modestly proportioned Eight-wheeler of typical profile of deep firebox, tapered boiler forward, straight stack, and oil-fired headlamp. The rear dome sat over the first driving axle and had a cylindrical cross-section with flat top. The smaller forward dome was thimble-shaped.
Locobase had thought that this engine might have entered service several years earlier than the T & FS date given here. But the B-1 class built in 1895 (Locobase 6829) is virtually identical except for a substantially higher boiler pressure.
The book also shows a 2-locomotive class with an 1893 service date that probably was built to the same design. A slight difference in heating surface (1,175 sq ft) represented by a slightly smaller firebox is all that distinguishes them.
The TF & S locomotive mentioned in Locobase 6826 was clearly the progenitor of this KCS class. The biggest single difference was a substantial boost in operating pressure, which may have been a railroad decision rather than a reflection of thicker boiler plate.
An early Brooks product built along classic American lines. For the period in which it was built, 132 was one of the smallest Eight-wheelers.
Although considerably larger than most of the KCS locomotives of the period, this class fell in the middle of American Eight-wheelers of the time. Its grate was quite small
Continuing a steady growth in Eight-wheeler size for the KCS, this quartet also featured driver diameters that allowed for reasonably fast running. But the grate area was still surprisingly small for the boiler and must have placed a relatively low limit on steam-raising.
