Ground Rule
Each Circuit the functioning of which effects the safety of train operations, shall be kept free of any grounds or combination of grounds which will permit the flow of current equal to or in access of 75% of the release value of any relay or other electromagnetic device in the circuit except circuits which include any train rail and except the common return wires of single wire single break signal control circuits using a grounded common, and alternating current power distribution circuits which are grounded in the interest of safety
Jumper Rule
The greatest possible care must be used when applying jumpers to keep to a min the amount of protection cut out by its use. The intention of these instructions are 2 fold 1st to guard against improper use of jumpers second to ensure their removal even though precautions have been taken to render their conditions entirely safe during their use. these instructions there fore apply reguardless of whatever else maybe done such are disconnecting circuits setting signals at stop securing switches and levers and other precautionary measures
When applying jumpers at highway grade crossings all applicable 600 rules shall be adhered to In addition the procedures for applying jumpers at highway grade crossings must be followed other then the excepted applications in 602c

The signal or ASC for the affected track governing the approach to every crossing where jumpers are applied must be placed at it most restrictive state at each crossing using line wires if necessary. to ascertain that jumpers have been properly applied or removed a shunt must be placed on all approaches and island circuits on all tracks ensuring crossing is functioning as intended. Verify by visual inspection that corresponding crossing approach relay de-energizes with shunt

The bridging of contacts in any vital signal circuit or the energizing of relays and contacts from any source which will any way impede the protection of such circuit controling device must be done in accordance with the following instructions : Signal control will be responsible for keeping a complete record of the application and removal of jumpers. Signal department employees instructed to apply the jumpers will be held personally responsible for their proper application and removal and must know that all vital signal circuits have been restored to their normal condition, If going off duty while jumpers are applied the signal department employee being relived must fully explain the condition to his relief
the use of jumpers for the bridgin of contacts is restricted to cases of absolute necessity, as when a switch, signal wire or apparatus is damaged resulting from a wreck, dragging equipment or similar occurrence; when necessary in connection with test specified in the 227 and when renewal of track structure cannot be taken care of otherwise and then only to avoid unnecessary delay to trains. Generally jumpers must not be used in connection with ordinary maintenance. When a condition arises nessitating the use of jumpers, signal control must have the authority for their use from the assistant cheif officer.
NOTE: at Harold and point when a condition arises necessitating the use of jumpers signal control must have the authority for their use from the designated transportation representative at pscc

Exceptions: the following applications do not require permission from the chief transportation officer, however notification shall be made to signal control:

Jumper across the XGN/GTNR
wiring a new relay in parallel for replacement purposes
energizing a flasher relay for lighting adjustments

Before jumpers are applied signal control must have a thorough understading with the signal department employee in the field as to how jumpers are to be applied. The signal department employee will explain to the block operator how the operation will be affected by the application of jumpers. before jumpers are placed in territory outside of interlocking limits, the block operator on each side of location affected by the use of jumper must in know addition to the train dispatcher must have full knowledge that jumpers are applied.

When signal department employee is instructed to apply jumpers, he must remove the jumpers immediately after the emergency ceases or work is completed. the signal system shall be tested to ensure that all is functioning as intended, then he must report to the block operator and signal control that the jumpers have been removed and normal conditions restored. Signal Control will advise the train dispatcher that the jumpers have been removed and the signal systems restored to normal

603
Jumpers must be orange in color, not less than eight feet of length of flexible wire not smaller than 16 awg and must not be coiled when applied. Jumper wires should have the proper connector to adequately secure the aforementioned jumper shall not be used with clips,
Exception: this rule shall not apply to swing wire jumpers or momentary jumpers used for the purpose of picking traffic or lock relays
710 Releasing Lock
Electric lever locks on electro-mechanical type interlocking machines or lock relays at all relay interlocking, must not be manually released except in cases of emergency, or when necessary on account of repairs, and then only upon authority from the chief transportation officer and signal control. the inspector maintainer of signals must make a detailed report on form CE 204 in conjunction with rules 711 712 713 and after authority has been received to manually release an electric lever lock or lock relay the following precautions must be taken
711
Signal Lever locks or AS relays
If a signal lever indication lock prevents a signal lever from being restored to its normal position, the lock must not be released until the inspector/ maintainer and block operator know that all signals directly controlled by the lever are in the stop position through visual confirmation from a qualified signal, transportation or M/W dept employee, and all distant signals governing the approach to these signals are in their normal or a more restrictive position except where the following precautions are taken.

A if the inspector/ maintainer and block operator know that the home signals controlling the affected lock are in the stop position and arrangement may be made by the chief transportation officer to notify all trains governed by the distant signal controlling the lock affected that signals are out of order and to proceed as though the most restrictive indication were displayed. In addition the inspector /maintainer must receive permission as per rule 710 at this time the signal lock magnet or AS relay may be manually picked up

B
Examiniation must be made as soon as possible to determine whether the lock failed to release on account of signal failing at more favorable than its normal position or because of a defect in the indication circuit. if lock failed to release on account of signal failing at more favorable than its normal position, be governed by procedure to be followed for investigating a false proceed signal See appendix H
712
Switches Indication locks or relays
Switch indication locks may be manually released after the switches have been properly secured and checked as prescribed by rule 705 706 708 709 where applicable permission must also be received as per 710
713
Switch lever locks, Detector locks or Switch locking relays
In accordance with rule 710 switch lever locks detector locks, may be manually released after being certain that there are absolutely no trains or engines on or approaching the switch. visual confirmation from a qualified signal, transportation or M/W department employee must be obtained before the detector magnet may be released by hand
714 traffic lever locks or traffic relays
Traffic lever locks may be manually released after arrangements have been made with the chief transportation officer through signal control to safeguard the movement of trains in the territory affected
715 Electric Locks on hand operated switches
Electric locks on hand operated switches may be manually released after permission is obtained from the chief transportation officer through signal control
732 air pressure rule
A. In the event of a 65 psi alarm switches shall be placed normal or in the position most likely to be needed

B. In the even of a 45 psi alarm switches shall be placed normal or in the position most likely to be needed. No Further operations are to be made until there is an inspector/ maintainer in the field to assist in the movement of the switches

C. Where circuits are so arranged that the ap- 30 relay is not in the signal control circuits Dunton hall and jay the following procedures shall be adhered too.

When the pressure is below 20 psi train shall be stopped at each home signal. Proceed signals may then be displayed. If switches are secured in accordance with 705 706 708 709
proceed signals may then be displayed without stopping trains.

where circuits are so arranged that the AP-20 relay contacts are in the signal control circuit signals will automatically display a more restrictive aspect when air pressure drops below 20 psi
