First mock up

So not wanting to leave a good idea alone and the fact that its well past 80F in the garden and I don't fancy mowing the lawn in that heat. I set to and mocked up the sketch plan. Though I am a visual person and can see things in my head pretty well I always think that on small layout like this there's no excuse for NOT throwing things down to confirm just how they look to see if there might be any issues with clearances etc:

Above: Here's the plan, you should be able to make out the edge of the baseboard in blue marker. You can see that there is plenty of room between the tracks and the central road will comfortably take four 60 foot cars. I also have a couple of 70' cars and there won't be any issue with them either.
Above: A down the layout view. I think the City classics Smallman Street warehouse is well suited for that location. It's a kit I love and should one find its way onto the layout it will be the 4th layout of mine to feature one. The team track on the front road before the warehouse denoted by the woodchip car is another device to stop folks seeing the trains move across their field of view.
Above: View from the road overbridge. The perspective of the "concrete canyon" between the two buildings is quite pleasing. I don't know if the Walthers Lakeville warehouse used is the right building for the site. Perhaps something different is needed there.

Now to sit on the idea for a while and see what happens...
