If I knew more about how the track circuits and distant signals to this
location were arranged, then I could tell you exactly why this signal was
set up this way. There was a reason.
The approach aspect was omitted because they did not need it. It could be
as simple as that another train would never follow one out, meaning a train
passing the signal would never need to "Proceed prepared to stop at next
signal", as the Approach aspect dictates.
