Sure! I started the Cakebox Challenge layout yesterday (Sunday) with the Scale Model Scenery Small Diorama Baseboard, a second-hand BR 01/02/03/04/05/06/07 shunter and a single 7-plank wagon. I've built up the weighbridge from RM and also placed a resin garden shed. For this exercise, only the best will do so I purchased a yard of Peco Code 75 Bullhead Rail (a personal first). Again, I've opted for the most expensive scatter and ballast, for added realism. So that's my cakebox: a shunter, wagon and some structures.
