WAGON
TURNTABLE
The
model represents the steel-plate type wagon turntable,
15ft. (4,6m.) diameter. These were found in goods yards
and industrial sites where space restrictions were such
that conventional pointwork could not be accommodated.
Their lightweight construction meant that locomotives
were prohibited from traversing them. Consequently,
they were often used in locations where shunting was
performed by tractors, horses or where capstan haulage
of wagons was employed. The table was turned by one
of two methods: a bar inserted into a socket provided
a means whereby the turntable could be rotated manually,
or a powered capstan was employed to turn the wagon
by means of a rope attached to one of a series of bollards
around the rim of the turntable plate. The latter method
is employed in the model. The capstan would have been
powered by its own electric motor, or by underground
shafting driven from machinery in a nearby building.
The
kit consists of an upper and lower board, separated
by spacers, the top board having a hole of suitable
diameter to accommodate the deck. The deck rotates on
a built-up roller bearing. As per prototype practice,
the deck has no rails but is provided with two grooved
flangeways set at 90 degrees to each other. These are
machined to fine-scale standards (29,0mm b-b), but other
standards are available upon request.
For
installation into the layout, the unit occupies an area
150mm. x 150mm.
A
motorising unit will be made available.
