S15 - a 2" gauge Locomotive

by LBSC

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.

    Castings

    When the design was originally published, Culhams and Kennions both sold the 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.
  • Coupled Wheels
  • Driving Wheels
  • Bogie Wheels (engine and tender)
  • Cylinders, etc.
