- A subroute is a lock on a single track section in a single direction, along a single pathway. Thus, a simple track with no pointwork potentially has two locks, one in each direction. A track with a single point has potentially four locks, a pair in each direction over the point in the normal position, and a pair in each direction over the point in the reverse position. A route between two signals locks a subroute over each track section between the entry and the exit signal. It may also lock sub[b]overlaps[/b] beyond the exit signal which, functionally and in object terms, is the same as a [b]subroute[/b]. Each [b]Subroute[/b] has a conditional statement which specifies the conditions under which it releases. [b]Subroutes Immediately After a Signal[/b] The conditions to release a subroute immediately after a signal are that the track section upon which it is located is clear, and that no routes are set from the signal [i]Example[/i] T123.c and R456(A).xs and R456(B).xs [b]Subroutes Not Immediately After a Signal[/b] The conditions to release a subroute that is not immediately after a signal are that the track section upon which it is located is clear, and that no preceding subroutes are locked. [i]Example[/i] T125.c and U123-BA.f
