There are three different types of petrol locos in use on miniature tracks.
1. Petrol with a clutch system
2. Petrol electric
3. Petrol hydraulic.


2. Petrol Electric

We currently have two of this type in our club, both very reliable machines.

“LLEWELLYN” was built during 2013 and has an eclectic body.  Looking at the “naked” photo the main part of this loco is the middle section.  A petrol engine drives two alternators, one for the drive motors and the other for the 12volt system on the loco.  The front bay contains horns (compulsory) and an air compressor and tanks for the brakes.  The rear bay houses all of the control “gear” for the loco.

‘LITTLE GOOSE” is our second of these engines.  Yellow and with a “honking” horn, it was created by one of our dedicated builders.  Hover your mouse over the picture and follow the arrows.

3. Petrol Hydraulic.

“GRONK” is a small but powerful loco thanks to the efficiency of a hydraulic transmission.  The power unit is a 6.5 h.p. petrol engine and the transmission is an Eaton type 700.

Its body is based on the English Class 08 - 13 of which over 1000 were built.  These locos appeared in Australia as the Class F of the Victorian Railways.  “GRONK” was built during 2015 and painted in the scheme of “MATEY” which is part of the display in the British Railway Museum at York.

1. Petrol with a clutch.

This type is a reliable system and  a good pulling loco.  Currently, our members have at least three of the clutch type.  It is a fairly simple system to create with a 5-6 h.p. motor and a reliable clutch followed by chain drive to the wheels.

The loco pictured is an Amtrac F40PH,  A passenger engine with a maximum speed 166 k/h as a standard gauge loco.

This model is powered by a 5.5 h.p. Honda engine driving through forward/reverse gear box.
