(1) Eng. 20 display signals and run as 1st No. 1 "A" to "Z."

(2) Eng. 25 run as 2d No. 1 "A" to "Z."

I

(3) No. 1 display signals "A" to "G" for Eng. 65. 2d No. 1 display signals "B" to "E" for Eng. 99. These examples may be modified as follows:

(4) Engs. 20, 25 and 99 run as 1st, 2d and 3d No. I "A" to "Z."

Example (1) is to be used when the number of the engine for which signals are displayed is unknown and is to be followed by example (2), both being single order examples.

Under examples (2) and (3) the engine named will not display signals.

Under example (4) the engine last named will not display signals.

For changing sections:

To add an intermediate section the following modification of example (1) will be used:

(5) Eng. 85 display signals and run as 2d No. 1 "N" to "Z." Following sections change numbers accordingly.

Under (5) Engine 85 will display signals and run as directed and following sections will take the next higher number.

To drop an intermediate section, the following example will be used:

(6) Eng. 85 is withdrawn as 2d No. 1 at "H.” Following sections change numbers accordingly.

Under (6) Engine 85 will drop out at "H" and following sections will take the next lower number.

To substitute one engine for another on a section, the following will be used:

(7) Eng. 18 instead of Eng. 85 display signals and run as 2d No. 1 "R" to "Z."

Under (7) Eng. 85 will drop out at "R" and Engine 18 will run as directed.

If Engine 85 is last section the words "display signals and" will be omitted. Following sections need not be addressed.

To discontinue the display of signals the following example will be used:

(8) 2d No. 1 take down signals at “D.”

Under example (8) 2d No. 1 will take down signals as directed and a following section must not proceed beyond the point named.

To pass one section by another, the following will be used:

(9) Engs. 99 and 25 reverse positions as 2d and 3d

No. 1 "H" to "Z." Under (9) Engine 99 will run ahead of Engine 25 "H" to "Z," and, if necessary, both engines will arrange signals accordingly. Following sections, if any, need not be addressed.

The character of a train for which signals are displayed may be stated. Each section affected by the order must have copies, and must arrange signals accordingly.

To annul a section for which signals have been displayed over a division or any part thereof, when no train is to follow the signals, Form K must be used.

(1) Eng. 99 run extra "A" to "F."

(2) Eng. 99 run extra "A" to "F" and return to "C."

Under (2) the extra must go to "F" before returning to "C."

(3) Eng.

run extra leaving

follows with right over all trains:

(3) Eng. 77 run extra leaving "A" on Thursday, Feb. 17th, as follows, with right over all trains:

This order may be varied by specifying the kind of extra and the particular trains over which the extra shall or shall not have right. Trains over which the extra is thus given right must clear the time of the minutes.

extra

(1) Eng. 202 works 7 A.M. to 6 P.M. between "D" and "E."

Under (1), the work extra must, whether standing or moving, protect itself against extras within the working limits in both directions as prescribed by rule. The time of regular trains must be cleared. This may be modified by adding:

(2) Not protecting against (eastward) extras. (3) Not protecting against extras.

Under (2), the work extra will protect only against (westward) extras. The time of regular trains must

be cleared.

Under (3), protection against extras is not required. The time of regular trains must be cleared.

When a work extra has been instructed by order to not protect against extra trains, and, afterward, it is desired to have it clear the track for (or protect itself

after a certain hour against) a designated extra, an order may be given in the following form:

(4) Work extra 292 clears (or protects against) Extra 76 east between "D" and "E" after 2:10 P.M. Under (4), extra 76 east must not enter the working limits before 2:10 P.M., and will then run expecting to find the work extra clear of the main track (or protect itself), as the order may require.

To enable a work extra to work upon the time of a regular train, the following form will be used:

(5) Work Extra 292 protects against No. 55 (or class trains), between "D" and "E."

Under (5), the work extra may work upon the time of the train or trains mentioned in the order, and must protect itself against such train or trains, as prescribed by Rule 99. The regular train or trains receiving the order will run expecting to find the work extra protecting itself.

When a work extra is to be given exclusive right over all trains the following form will be used:

(6) Work extra 292 has right over all trains between "D" and "E" 7 P.M. to 12 night.

This gives the work extra the exclusive right between the points designated between the times named. Work extras must give way to all trains as promptly as practicable.

Whenever extra trains are run over working limits, they must be given a copy of the order sent to the work extra. Should the working order instruct a work extra to not protect against extra trains in one or both directions, extra trains must protect as prescribed by Rule 99, against the work extra; if the
