The other change not shown is moving the staging to the courtyard and this will be discussed in detail later. But in principle will involve the use of two four  meter staging yards mounted on lifting trolleys mounted on 40 mm od pivots. This will be outline latter but to say the availability of cheap workshop lifting equipment from China had made this idea possible.
Spicer's Creek Loop
A previous blog on Spicer's Creek showed snap shoots of the station diagram. The design only creates a basic loop only. A cut down cattle pens will be included along with locomotive watering and a PC1 shelter. This will be cut from a ModelFxs PC2 station that will be combined with another to create a AC4 station for Goombla. To operate a steam era layout of the 1960's loop sidings are critical to achieve practical operation.
Drill Creek has incorporated the lot PC2 Station, Watering, Cattle Pen, Loading Bank and SO8 Grain Silo. The line will exit to staging at MaryVale through the wall of the garage.
The design of Goombla was outlined in the previous blog the most important part of the new design. The train will enter from external staging representing Golgong using a narrow shelf that is just scenery. The entrance will be hidden using row's of heavy foliage as was the exit from the original Spicer's Creek Modules. It has been carried to the front edge of the Spicers Creek Station Module to help operators feel that these modules are extension visually of that module.
The loops that join all the modules at the rear are also external and located between the rear fence and wall of the shed. This is lost space that is never used and helps save precious space to allow a series separate scenes [stages] to existing in their own right. In modeling curves are extremely difficult to scenic and serve to define the distance between any two scenes creating a real sense of small distances between model areas and are best done away with.
