It seems I missed publishing a post on this topic to my RMWeb blog. It can be found here on my person Grogley Junctiion blog https://grogleyjunction.blogspot.co.uk/2017/07/back-to-big-project-signal-diagrams.html If you do go to this link to fill in the missing thoughts on how I came to the current post I think should warn you it is a bit of an epic post, otherwsie please read on to what I hope is the final plan for the start of this project.

Again, after much thought, I proposed a further trackplan for consideration to Mr Severs and he very promptly came back with some sound advice. So unless someone can offer any further constructive advice I think the below plan for "stage one", Polbrock engine shed, will be rubber stamped "Approved".

As can be seen I agree with previous advice given that the double track between Polbrock and Grogley would not be typical of this stretch of line. I feel Mr Servers thoughts on the signalling, along with the addition of the "Sand Drag" to protect the Padstow Wadebridge line, could well satisfy the BoT. One comment he did make was he thought the LSWR would have built the engine shed at Grogley Junction. I do agree and there may well have been space. The problem I had when revisiting the Grogley's track plan was that I could not find a way to fit the engine shed at Grogley where it would have been located and have enough room in the "Man Cave" for a work bench. If only the "Cave" could be 2-3 foot wider...

I've drawn the track plan in Templot and to me it feels good. It will offer operational interest for one person to build and operate. It will also be a good stepping stone to continue on to Grogley Junction for the building of rolling stock.

The two three-way turnouts need to be completed in the above Templot track plan. Even so I printed out a full size plan as a discussion point during last week's Scalefour meeting and it seemed to gain approval. Very rough full size mock ups have also been created of the engine shed and water tower to test location and size against the track plan. I'm now investigating how to build them. The initial plan was to build them using Wills Plasticard. During the last Area Group meeting a comment was made about making a master of a section of the engine shed wall, then to take several resin castings off the master to build the shed to save some time and effort. Seems a good plan to me especially as I've never scratch built any building before.

I'm now looking forward to posting about progress on this project and further tweaks on Tredethy Wharf.
