The original idea for my design was to run it as an end to end but with the 'extra' curve put in to allow a continuous run. The continuous run mainly being there as a facility for :
a) Inexpereienced operators if left in the lurch!
b) 'Running in' new locos.
c) Keeping something running whilst answering punters questions - how many layouts 'die' when the operator is talking?
We could extend the length of the hidden runround loop and shoot a siding off it onto a 2-track turntable (or traverser, which ever fits better) inside the boiler house. If the rear runround is lengthened then a removable cassette could be put it right at the back, as Gerry Bullock says some extra stock storage space is required.To answer Gerry
Q.1 Both runrounds are required to 'right end' the loco after exchanging wagons on the boiler house and potting shed traversers - although the traversers would be better replaced with 2-track turntables. NOTE Locos do not enter the buildings.
Q.2 If a Farm Shop was added between the warehouse and the boiler house we would then have a purpose for passenger trains and we could have a ground-level platform on the front runround loop. So Yes, it's not shown.
Q.3 The ideal thing for the wagon turntable and on up to the greenhouse would be Steve Bennetts new battery Truck or even a Midge.
With Alastairs revamp the main thing I like is that all the buildings are not 'square-on' as I have mine and also with the wagon turntable it would be easier to exchange/propel wagons.
May your wheels never rust.
