The Points Box remained in use until the summer of 1970 when the point work of the Port Erin arrival platform and its associated signals were disconnected. These points were then controlled with hand levers and the signals were placed permanently in the 'off' position so that trains could arrive and depart without the box being manned, saving the associated wage costs. Thereafter, it was used only for more complicated shunting movements in which case it would be manned by a member of the train crew or the stationmaster. The remainder was taken out of use in 1979/80 when the old Port Erin Platforms - 5 & 6 - were removed and the area cleared for parking.
