S15 - a 2½" gauge Locomotive
The S15 is a much undervalued design. The two locomotives that are
currently "in service" behave very well. It is a straightforward design
with no surprises, other than that it is a long reach over the bogie
tender. It is a pity that there is no single source of parts.
Frames 19" overall
Coupled Wheels 2_7/8" diameter
Cylinders (Slide valve) 13/16" bore x 1_1/8" stroke

When the design was originally published, Culhams and Kennions both sold
necessary castings to builders. None of the patterns are known to exist
now. However, prospective builders need not despair. Many castings
intended for other designs that are available can be used. Suitable
wheel castings can be obtained from Turn of the Century Wheels.
Bogie Wheels (engine and tender)
Smokebox Door and Rings, Chimney, Dome
