Peninsula benchwork continues …

Hi all,

As I am still waiting on a parcel of track to arrive from the UK, work on the helix has come to a standstill.  In the meantime, I have been continuing on with some benchwork on the peninsula.  As the spline has been approaching the teardrop on the peninsula, the height of the risers has been getting quite high, which I found was resulting in a slightly unstable roadbed foundation, so I decided to build a second layer of joists to strengthen up the construction which in turn will shorten the risers.

This second layer of joists has also filled some of the ‘void’ between the spline and the bottom joists.  This will save a lot of scenery ‘filling’ for no reason.  Plus I didn’t really need so much depth below the spline.  Refer to the pictures below.

The spline has also been set at the correct grade right up to the end of the teardrop.  The photo below shows just how much the track will climb from the bridge at Chilcotts Creek (the gap in the spline on the right) to the teardrop.  At this point, there is approximately a 13 inch (330mm) difference in height.  The distance to this point is around 81 feet (24 metres).

The roadbed around the peninsula  is now starting to get to a good height.  I can just visualise the trains climbing this grade now!!

That’s all for now.  Hopefully the next update will be on the next stage of helix construction.

Cheers for now.
