stations may be specified.
Kilometer posts are wooden or concrete signs
posted along the track and numbered consecutively from one end of the
division to the other.
Inserted in the orders instead of the station
designators would be "....From Kilometer Post 27 to Kilometer Post 29...."
or "...From Kilometer Post 32 to Kilometer 33.5...." The approximation used
is necessary because the posts are spaced only in whole kilometers. Another
form of area designation might be '....From Kilometer Post 13 to Bridge
This method pinpoints the work train's area and eliminates an
approaching train's expecting to see work-train flagmen anywhere in the 10
or 15 kilometers between two stations, if they had been specified instead of
When the time specified in orders expires, the work extra is in the same
position as a regular train that has lost its schedule; it is dead with
respect to any train standing. It must clear the main and seek new orders
or authorization to return to its home terminal.
If the work-train crew
finishes its work an hour before the time expires, the crew cannot start
back to its home terminal without contacting the dispatcher. Why? Because
the train's original right is confined to the area specified by the working
limits in the original orders. Three examples of form D-H orders are given
in the subparagraphs following.
a. First example. "Eng 3031 Works Extra on Eastward Track 0801 Hours
Until 1701 Hours Between AY Tower and LY."
b. Second example.
"Eng 3031 Works Extra on Eastward and Westward
Tracks 0801 Hours Until 1701 Hours Between AY Tower and LY."
may be supplemented with the following: "...Not Protecting Against Extra
Trains." or "...Not Protecting Against Eastward (or Westward) Trains." Once
a work train has received orders not to protect against extra trains, and it
is later desired to have it protected against a designated extra, the
following additional order may be used: "Work Extra 3031 Protects Against
Extra 210 West Between FV and BO After 1330 Hours." This order tells the
crew of Extra 210 West that it must not enter the area specified before the
time shown in the order. After 1330 hours, however, the crew can expect the
work extra to be in the clear or protecting itself according to the terms of
the order. Should the order specify that the "Work Extra Will Clear" and
for some reason it cannot do so, the flagman of the work train would be far
enough to the rear to stop Extra 210 West.
c. Third Example.
The widest range of right that could be conferred
upon a work train in a designated area would be as follows:
