The turntable at Whiteman Village Junction came from the
old WAGR steam loco depot at Midland Junction. It was originally built as a
70’ diameter turntable, but was extended during World War 2 to 80’ diameter
to accommodate the Australian Standard Garratt locomotives introduced at that
time. This is why it is rather unusual in that the perimeter rail is some
distance in from the ends as this was retained in this original location when
5’ was added to each end of the turntable.
The turntable girders, pivot, and perimeter rail, was
acquired by the State Planning Commission in the early days of Whiteman Park,
around 1984, along with a number of overhead gantry crane girders which became
bridge girders for the railway. After many years in storage, a suitable site
became available, and with assistance from Park Management, the railway
undertook the installation.
Work
on installation of the turntable
commenced in 1993
The pit was excavated by “Construction Training” as
part of their earthmoving machinery operator course.

Simon Mead co-ordinated the rest of the installation on
behalf of BBR. This work involved:-
 | Forming
and pouring of the concrete footing for the central pivot, comprising over
40 tons of reinforced concrete |
 | Construction
of drainage sump and oil trap in the pit |
 | Restoration
and painting of the girders |
 | Restoration
of the centre support pillar and the bearings |
 | Transport
of the girders to site and installation in the pit |
 | Construction
of the brick pit wall and backfilling behind it |
 | Fabrication
of transom girders to support the 610mm gauge track (the original 1067mm
gauge track was supported directly above the main girders, however these are
too far apart to directly support the narrower track) |
 | Installation
of steel walkway decking salvaged from Claisebrook Railcar Depot (the
turntable originally had a timber deck, but the steel deck was available at
transport cost only, and would be much less maintenance, and accommodated
the track support transoms easier.) |
 | Construction
of approach track |
Almost all this work was undertaken by the volunteers of
the BBR, too numerous to mention. The only jobs undertaken commercially was the
sandblasting of the girders, craneage and transport, and construction of the
brick wall.
The
turntable was completed in 1995 and was first officially used to turn NG 123 on
Enthusiast Day
