I am aware what the SPT is used for, merely stating that there (appears) no rule against a member of public using one (if in a public accesable area) to report possible emergencies, and lets remember that drivers are not the sole use of such SPTs.
Unless things have changed, if a track circuit drops after the passage of a train there is no requirement (at least on TCB lines) for the offending train to be stopped and examined unless more than one circuit has dropped.
