I was writing a few days ago about how the track on Bron Hebog climbs all the way from Beddgelert station around the S bends.
On the real railway this section has a ruling gradient of 1 in 40.
As I was explaining, we haven't calculated whether Bron Hebog will reproduce this to scale - nor have we any intention of trying to work it out - but our little trains will most definitely be seen to gain height.
This picture shows the work done so far to set out the entry and exit points of the trackbed around the 180 degree bend and the difference in level is clear to see.
And if you look from where the public will be watching from at exhibitions at the very centre of the S the difference in height between the 3 sections of track is very striking.
Click on the picture to enlarge it and you will be able to make out the little wagon sticking out of the bottom of Cutting Mawr at the top of the picture.
If you will allow me to say so myself I think this bit is going to look very impressive when it's finished.
