Douglas Railway Station is a somewhat rambling structure (as is required by its function) and is constructed of red brick with pitched slate roofs and a major glass roofed 'lean-to' entrance corridor. The profile of the brickwork has been adapted to approximate to the platform roofing requirements in a decorative fashion. Similarly the accommodation areas of the station have received some definition with brick pilasters and string courses of geometrical rather than structural significance. Because the building is sited in a hollow, there is an imposing gateway and clock in a detached structure located to be visible along Athol Street. This structure with its twin cupolas and central arch is well resolved but only related to the main station by a rather small scale brick and iron paling fence to the gate enclosing the station yard.
