There are three types of allowance that may be added to a timing point location for a train.
Engineering
This is extra time to allow for a speed restriction on the railway.
It may also be called 'Box Time', as the Working Timetable encloses engineering allowances in a box or square brackets.
Pathing
This is extra time to ensure the train path doesn't conflict with others at a junction, or where trains running at different speeds are operating over a route.
It may also be called 'Circle Time', as the Working Timetable encloses pathing allowances in a circle or brackets.
Performance
This is extra time to provide a margin or buffer for late running on a day-to-day basis.
It may also be called 'Diamond Time', as the Working Timetable encloses performance allowances in a diamond or angle-brackets.
