Project Overview

Project 3102

3102 has been out of service for some time, and after conversations with several members, it would appear that the scope of work required to return the locomotive to service will be very similar to the list below.

Tender

The tank is corroded beyond economical repair, and so will require the fabrication of a new tank and bunker, to the same design by Steven Buck, used to build a new unit for 3016. The existing underframe and bogie's are believed to be serviceable, and so will be inspected and repaired as required.


New tank $30 000
Locate all components eg bogie's, axle boxes, brake rigging
Check frame and drawgear for cracking and wear
Construct new air reservoir, piping
Construct through water piping; including provision for filling from ground level
Reassemble and paint tender unit

Project General

One of the first things to be done when the project starts will be to find all the components that once made up this locomotive. Over the years the parts have been used to keep other locos operational, pilfered by souvenir hunters, or in some cases just misplaced, so it will be neccecary to find all the bits that remain and then work out what is missing.

  • Locate all components
