Whittingly - To Extend or Not?

After my last post considering what next for Whittingly I've pondered on the feedback and the practicalities, and sketched an alternative idea - Plan C? In this case, short 6" extensions are added to both ends of the scene, being fixed extensions to the baseboard where marked with arrows on the plan. That on the left provides the spur beyond the platform canopy and extended hospital buildings, while that on the right extends both loop lines and the engine shed. The overall board length is now 3' 6" which is still easy to store and handle, while a separate fiddle yard need only contain a turntable or sector plate. 

This is difficult to picture in 3D, so thanks to the visualisation possible with CAD (card aided design) using cereal packets, here's a mock up of what this plan might look like. 

At the left-hand end the front track protrudes beyond the platform canopy, providing somewhere for the loco to rest in view. Most of this extension is taken up with the stores building, which would need to be extended from the low-relief building on the existing board - this is likely the most difficult task since brickwork would need to match and I'd rather not lift the existing building. I've not mocked it up but behind this the boiler house roof would need extending too, but there is space for a curved backscene, and perhaps a tall brick chimney? The left hand end could feature a flat/low relief wall of the main hospital building. 

At the right-hand end the two loop tracks are lengthened. The engine shed and its siding would also need extending, the back of the shed just being an open hole against the backscene - and as it is at an angle, it would be difficult to extend. Making the extension in corrugated iron as if a later add-on might make things easier (and more interesting), though matching the roof could still be tricky. In the foreground, I might move the tree to the right (perhaps with a second tree) to hide the exit. There could be space for a footbridge as a view block, although I don't think it is needed. 

This view shows that the lengthened loop lines will allow plenty of clearance to run around 4 wagons or two 6-wheel coaches while they remain on scene. The fiddle yard still completes the run-round loop so the loco must go off-scene; extending the scene to fit a point in adds at least 18" as in Plan B in the last post.

So, this all looks possible, although extending the buildings looks difficult without removing them from the scene, with the resulting ground cover damage to make good. The question is, are these extensions worth the extra effort? The alternative remains Plan A, which effectively has the extended trackwork but in non-scenic areas, and so keeping the original scene unmodified. The scenic extensions of Plan C means that more of the trains are visible more of the time, and the scenic frontage of the layout is increased without increasing the overall length, but operation is unchanged. 

I'm interested in your views!
