Before I began building
my G scale garden railway I did a lot of planning and measuring to
ensure the railway would fit neatly into the 30ft. x 30ft. garden.
When building a garden railway always try to use the largest radius
curve that you can and for me this was 4ft. so I bought four LGB R3
curved sections and two straight sections to help with the planning
stage. When I was happy with
the design on paper, it was time to start building the track bed
around the garden. There are many methods of track bed construction,
from laying the track directly onto ballast at ground level or
a raised track bed supported by posts.
My own method of construction
was determined by the natural gradients of the garden and the
features within the garden. The track bed varies in height from 5 to
3 inches off the ground, this allowed the railway to run along the
front of the decking and enter the flowerbeds at ground level.
The track bed
is constructed using tanalised decking planks, supported on timber
blocks. Two planks were laid side by side one for each track and a
gap was left to allow for drainage and cables. The tracks in
the picture are the four LGB R3 curved sections that were used for
setting out the curves.
With the decking planks in position they were covered with a light
grade mineral felt to provide a good surface for the track to sit on
and to protect the decking planks from the weather.
The mineral felt will hold rain water on its surface, so a slight tilt across the track bed will allow the water to drain away. I was
able to cut drainage holes in the middle of the felt and cover them
with a plastic mesh to stop the ballast from falling through.
This method of track bed
construction was used right around the garden.
This picture shows the
track bed curving around the shed, the decking planks were cut into
wedge shapes and placed together to make the curves. Its a bit
harder to do but it turned out well.
The track goes into the shed at the top of the picture to allow
trains to be stored and serviced when not in use.
Finally, a before and after
shot showing the flower bed, or what's left of it, cleared of plants
to allow the track bed to make its way around behind the large
conifer. The track along the fence is a single line section.
That's the track bed completed, the
next stage of construction was building the two tunnels. This was
done before the I laid the track to prevent any damage from falling
rocks...! click the tunnel construction link at the bottom of this page.
