An examination of the two columns shows the exact number of minutes in the
shortened schedule in column 2. The engineer on No. 19 will make up all the
time he can within the limits set forth in column 2. If he fails to meet
the faster schedule, his train will be permitted to leave the stations later
than the time shown. Under no circumstances will the train be permitted to
LOSS OF TIMETABLE SCHEDULE
On occasion, a scheduled train may lose its right and its schedule.
With a loss of schedule, the train loses its right to continue occupying the
Losing its schedule and having its superiority restricted,
however, are entirely different and the distinction must be clearly
A train may have its timetable superiority temporarily
suspended by a train order which restricts it. Two examples would be (1)
putting a relatively unimportant scheduled train into a siding to eliminate
stopping and delaying a heavy extra or (2) sidetracking a scheduled
eastbound train (when east is the superior direction) while a westbound of
equal class is kept moving. These restrictions are only temporary, and the
train continues on its normal schedule after the train order is fulfilled.
However, on two occasions the train actually loses its schedule and hence
its superiority: when it is more than 12 hours late and when the timetable

12 hours late, it is said to "die on its schedule." This means that it has
lost its schedule and that all train orders, if it holds any, are annulled.
The train can proceed from the point where it loses its schedule only on new
train orders from the dispatcher.
Rule 82 of TM 55-200 provides that
"...Regular trains more than 12 hours behind either their scheduled arriving
or leaving time at any station lose both right and schedule, and thereafter
can proceed only as authorized by train order."
