As exclusively predicted on this blog - as we're wont to say in my professional life - Bron Hebog now has a temporary fiddle yard at the other end.
Himself has adapted the blank end baseboard, giving it a plywood top and laying a pair of sidings.
You can see how the sides have been shaped to match the profile of the Goat Tunnel board.
Once it has done its duties at Sparsholt and Railex the plywood will be taken off again and the final trackbed will be formed and track laid towards Cemetery Crossing which will lead into the proper fiddle yard at the back of the layout.
This bodge up will do the job well enough this weekend, though.
