Stonehaven signal box is a delightful structure that presents in excellent condition and looks to be relatively unmolested, even the windows look original. It is a Caledonian Railway (Northern Division) Type 2 box installed in 1901 in a prominent position on the up platform next to the station building. According to Historic Environment Scotland, it is of historical importance along with the station as a whole having a "piend-roofed, rectangular-plan signal box comprising painted brick base with two blocked round-arched openings flanking shallow projection at centre, and small-pane glazing to timber frame windows to NW, NE and SW. Small boarded timber outshot to left at SE. Timber forestair to signal cabin. Grey slate". When the mechanical signalling is replaced in the coming few years I think that it would make a great station café rather like Totnes, see.....
