As a result of this, St James's terminating facilities were no longer regularly used. The signal box remained in use until 1990 with the occasional train continuing to terminate at St James to keep the siding tracks usable for emergencies and railway staff familiar with the procedures. In 1985–86, the signal box was taken out of service for an asbestos abatement project. During this period, train cars allocated for the removal of the asbestos would occupy one or the other of the dead end sidings, which meant that regular use of those lines by passenger trains was not possible. After the asbestos abatement project was completed, the signal box was returned to service until 1990, when asbestos was discovered in the signal box and the sidings. From that time the signal box was not used, and the signals and siding tracks were eventually removed. The sidings were formally closed on 27 July 1991.
