Petrol locomotive "JOY"

0-4-0 Diesel Outline Shunter.

reg The loco is powered by a Ford engine via a 200 amp aircraft generator, to another similar generator which acts as the traction motor.
Joy was the principal locomotive for the railway for many years running the Sunday passenger service. The P11, Reg, is taking over this duty now.

The diesel shunter was built at Arncliffe, Sydney by Keith Mears for the Sydney Society of Model Engineers in 1961. They had an 8” (203mm) and 12” (305mm) dual gauge track at Ashfield. This locomotive was their main club workhorse for many years, both at Ashfield and at their later property at Luddenham. The abundance of steam locomotives meant that in 1990 this locomotive was no longer used. In 1994 it was purchased by MSTEC member, John Davies, and made available for use on the new track at Scoresby. Later, John gave it to MSTEC.
