Many railroads sidetrack slow-moving passenger trains to let "time" and
symbol freights pass.
While usually classified as extras, these trains
operate on a time schedule even though their schedules are not listed in the
operating timetable.
They haul high-class freight that usually produces
more revenue than the first-class trains.
They exercise no right over
regular trains, however, unless such right is conferred on them by train
order.

EXTRAS
A large number of the trains on any railroad may be designated as
extras.
They are not listed in the timetable and run whenever sufficient
freight or tonnage is in a yard to justify their operation. Also, it may be
necessary to run additional passenger sections, especially during the
vacation and holiday seasons. In addition, extra work trains--work extras--
may also be run.
For the purpose of documentation, all extra trains are always so
designated, such as Extra 310 East, or Work Extra 9220.
Work extras are
work-trains from which employees perform track maintenance and construction
along the right-of-way between specified points. Because these trains must
move in both directions; no such designator is used when referring to them.
Unless otherwise provided in a train order, a work extra must clear all
regular trains and protect against other extras in both directions. A work
extra may not protect against a regular train, that is, work on the time of
an overdue scheduled train under flag protection, unless instructed to do so
by a train order.
To distinguish between extra trains and those regularly scheduled, the
extras display white flags by day and white lights at night on the front of
the locomotive. Note the white flags mounted on the passenger extra shown
in figure 4.1. If more than one locomotive is used on the head end, only
the forward engine carries the signals.
These extras must always comply
with rules 86 and S-87 quoted in paragraph 1.4a, b. Scheduled trains do not
display signals except under the conditions cited in paragraph 4.7.

SECTIONS
In handling passenger trains, running additional sections is frequently
necessary.
A section is one of two or more trains running on the same
schedule.
Technically speaking, and especially in the dispatching and
telegraph offices, there is no such thing as a passenger train.
It is
either a train with a class designator, or it is an extra.
This is
important for operating employees also. If a
