---- will run extra from —— to ——.
EXAMPLE.
(a.) Eng. 99 will run extra from Berber to Gaza.
A train receiving an order to run extra is not required to guard against opposing extras, unless directed by order to do so, but must keep clear of all regular trains, as required by rule.
A "work train" is an extra, for which the above form will be used for a direct run in one direction. The authority to occupy a specified portion of the track, as an extra while working, will be given in the following form:
(b.) Eng. 292 will work as an extra from 7 A. M. until 6 P. M. between Berne and Turin.
The working limits should be as short as practicable, to be changed as the progress of the work may require. The above may be combined, thus:
(c.) Eng. 292 will run extra from Berne to Turin and work as an extra from 7 A. M. until 6 P. M. between Turin and Rome.
When an order has been given to "work" between designated points, no other extra must be authorized to run over that part of the track without provision for passing the work train.
