The goods shed was constructed in a different style to the station building, its character owing more to local traditional construction. It housed a crane and a side loading bay with tall doors and a canopy for road vehicles; a smaller office building was tacked on to the side. The adjacent goods yard was served by five sidings. In addition, eight railway cottages were constructed nearby for staff. Access to the goods yard and exit from the Down loop serving platform 1 was controlled by "South Box" (or "B Box") which was brought into use on 27 April 1902 and situated to the west of the station, although it was only infrequently used. On the opposite side of the station at the end of the Up main line platform was "North Box" (or "A Box"), which replaced a previous box known as "Stammerham Junction" dating from 1865, possibly at the same time as South Box was brought into use or even a few days earlier. The station opened on 28 April 1902, although the official ceremony took place on Thursday 1 May 1902. The station was initially known as "Christ's Hospital (West Horsham)", but when tickets were issued to travel to Christ's Hospital school for its opening ceremony on 29 May 1902, they were made out to "Stammerham Junction". Special trains bound for the school departed from at 1520, at 1525 and Sutton at 1540, all due to arrive at Christ's Hospital at 1645. Some of the schoolmasters were dispatched to Victoria and London Bridge to meet the pupils. A report published in the "West Sussex Gazette" on 1 May 1902 called into question the wisdom of constructing such a large station for an area which was relatively sparsely populated. The initial service consisted of ten trains to Victoria, seven to Guildford and four to with served by three stopping services. In the event, the LB&SCR's expectation of an income from the station to match the size of its premises would be defeated by two developments. Firstly, Christ's Hospital school only ever accommodated boarders; the LB&SCR had possibly not been informed of this when designing the station. Secondly, the anticipated residential development in the area did not materialise. This was largely because the school had purchased much of the land around the junction and had no desire to see their green fields filled with housing, the school having left London precisely to reestablish in greener surroundings. The LB&SCR was therefore left with a white elephant: the capacity and stature of the station being vastly out of proportion with its status as a useful rural interchange, rather than an important railway junction serving much of West Sussex.
