First, thanks all for your helpful comments.

Well this all started last year when I found this photo in my collection, it appears to be “Concrete Bob†37425, just about to top County March summit, hard to think that this was an ordinary service train.

it looks like I am going to jump in at the deep end, and make a start on Bridge of Orchy

A few things,

The doughnut design, I have had a ply around with a conventional layout, but to fit on say a 3' by 8' board, I would start to get tight bends, and that is one of the things I was trying to avoid.

Number of boards in the doughnut, I had a play around with 7, but, I would then only be able to have 3 scenic boards, because of matching them with the fiddle yard boards, to form a box, and still get the whole thing to fit in the car. So it looks like I am stuck with 6, which will make up into 3 box's.

Track and wheel standard, I think I am going to go for the compromise, I have read Toms blog and Eldavo's thread, and for me it looks the way to go. The main reason for this is, I am going to need about 8 trains, of 6 to 7 coach lengths, and it would be a lot to convert. I will order the bits and have a go.

Track construction, Easitrac , for the plain track, and some points built using Easitrac components. A lot of the mainline, is, was flat bottom rail and pandrol clip design, so where the turnouts are built using this method, I will use FB rail and PCB sleepers.

Control, DCC again, and if I can afford it! With sound, it is yet to be seen, or rather heard, weather a sound fitted class 37 can make enough noise to represent one slogging up County March!.

I have had a bit of a dabble, and produced a 2mm association mineral wagon kit, and had a go at making some D&G couplers.

Thanks
