via three sets of brick and concrete steps, set symmetrically in the centre and toward either end, each of which has a double staircase. These have the same decorative iron balustrade as the main stand. Between the staircases at the front of the stand are concrete seating tiers with slatted timber benches. Behind the seating tiers the rear brick wall has arched openings with the same decorative metal balustrade as the stairs and front and sides of the stand. There is a rear promenade at this level, but several tiers of later timber seating have been installed here, restricting pedestrian circulation. Because the land is flat and the stand is so high, there is a very tall rear arcade promenade (traffic-able to vehicles and pedestrians) running the length of the stand beneath the upper seats and a huge sub-floor beneath the remainder of the stand. The brickwork in this section of the building is in red face brick, with decorative dark-glazed bricks to the arches along the arcade and supporting the upper seating tiers. The large sub-floor is divided into four main rooms, accessed mainly off the rear promenade. Each of these spaces has a ripple iron ceiling which follows the slope of the seating tiers above, a concrete floor a step or two below street level and windows and doors opening both to the promenade and to the front of the stand overlooking the arena. The northern room is utilised by the St John's Ambulance Service and has been divided by sheeted partitions into cubicles. Facilities include an early iron-framed, wheeled ambulance stretcher. The southern room has been converted into an English-style pub, complete with appropriately decorated entry. There are toilets located at each end of the subfloor, accessed from the front – the men's toilet at the southern end and the women's at the northern end. The men's toilet retains an early lead-light fanlight above the entrance door, but both facilities have been remodelled internally. 6. Machinery Hill Stands (1950s) These consist of a number of uncovered stands, curved around the northern perimeter of the Main Arena, between the northeast end of the John MacDonald Stand and the Marshalling Yards at the northeast end of the arena. They are of concrete construction (concrete seating tiers supported on concrete piers), with brick or concrete in-fill to the sides. The seating consists of curved, slatted timber benches and is accessed
