We've been deploying a precision piece of modelling equipment this week - the felt tip pen.
Himself made use of a spare hour to sketch the outline of the trackbed in the middle section of the S bend immediately behind Beddgelert station.
If it seems a bit wide for OO9 here it's because a new farm road follows he line of the railway along here, one of the mitigation measures agreed with the farmer at Cwm Cloch when the railway became a railway once again.
The track sits a bit lower than the line but Himself is hoping to be able to cut it out of one piece of plywood and jigsaw a slit and bend the wood to separate the levels.
The end-on view above shows how the line does not take a straight course between the two big bends but snakes around.
Our reverse curve is not as pronounced as on the actual railway which is a consequence of us having squeezed the S bend back towards the station a little to make it fit better into the rectangular outline of Bron Hebog, but I doubt if anyone will ever really notice.
(They never did when we pulled the same trick on Dduallt)
