he would not predict or guarantee to anyone that the train was going to be
50 minutes late at every station between its points of origin and
destination. Other trains and yard crews would not know the precise time to
expect the train, and they could not depend on using the full 50 minutes
because this figure might be progressively reduced as the train traveled
over the division.
When the dispatcher issues the run-late order, he is
guaranteeing to everyone concerned that the 50 minutes will not be reduced.

effect, it is saying: "No. X will be allowed to make up 20 minutes between
A and E. It might make up less, but it's not going to be permitted to make
up any more." The order specifies that the train may not leave a station
before the time shown opposite the station name. A wait order for No. 19,
under the conditions just given, might read as follows:
19 Engine 3130 Wait at
Ogdensburg Until 1838

The dispatcher, in effect, writes a new schedule for most of the run. Also,
he shortens by a few minutes the individual running time between certain
stations. A comparison of the running time between stations can be made by
examining the two columns that follow. The times and stations of the run-
late order are shown in column 1; the stations and departing times of the
wait order are listed in column 2.
Column 1--Run-Late Order
Column 2--Wait Order
