DEAD LOCO MOVEMENT
(FOR DETAILS, REFER RAILWAY BOARD LETTER No. 2000 /M (L) /466/803/Pt. dated 28.06.2006)
Hauling 3-Phase loco fitted with E-70 brake system as a dead loco.
These locomotives are fitted with electro pneumatic E-70 brake system. These locomotives in dead condition can be hauled both by locomotive fitted with IRAB-1/28LAV-1 brake system and locomotive fitted with E-70 brake system.
If these locos are coupled with conventional A.C. locos as a dead, then direct loco brake application is not possible by SA-9 since MRE & BCE can not be coupled but if BP is dropped from live loco, conjunction loco brakes application will take place in dead loco.
A) Hauling dead WAP-5/WAG-9 electric locomotive fitted with E70 brake pipe control system in a train.
1) Switch off BLDJ and lower the pantograph of the loco to be sent as dead. Isolate the pantograph through panel isolating cock on pneumatic panel.
2).Switch off CEL as follows:
a) Operate BL-key from ‘D’ to ‘Off’ (wait for 2 sec.)
b) Operate BL-key from ‘Off’ to ‘C’ and wait until display screen, LSDJ, and UBA goes off.
c) It indicates that CE is get’ OFF’ and now rotate BL from ‘C’ to ‘OFF’. Switch off the ‘circuit breaker control circuit locomotive’ (112.1) in SB2 panel.
3).Couple the dead loco in the train.
4) Put auto brake controller (A9) in “Neutral” position in both cabs of dead loco.
5) Put the direct brake controller (SA9) in “Release” position in both cabs of dead locomotive.
6) Drain the Main and Aux. reservoirs of dead locomotive completely. After draining out, close the drain cock of main reservoir and aux. reservoir.
7) If loco brake in the dead locomotive have not got released, which can be verified by observing the BC pressure gauge, then release the same in the following steps.
A) Manual handle of distributor valve at pneumatic panel should be operated manually to release control pressure. BC pressure shall automatically vent through D2 relay valve to release loco brakes.
B) In case residual BC pressure remains in brake cylinder line, the BC pressure should be released through bogie isolating cock of both bogies. Make bogie-isolating cocks in ‘Normal’ position after releasing the BC pressure
8) In the dead locomotive, ensure isolating cock position in the pneumatic panel as follows. (Towed dead):
9).Connect BP pipe of the dead loco to the BP pipes of load and open BP angle cock of both of loco and load side. The aux. reservoir on dead locomotive will get charged from BP supply. Check the BP pressure gauge in the cab of dead loco. It should show the same pressure as that of the load in case of load (In case of locos are to be attached on a train having twin pipe i.e. both BP and FP then FP of dead locos should also connected and its angle cock should be opened.)
10)Lock the parking brakes in applied condition. This procedure is safe to avoid brake binding and condensation of moisture in the parking brake cylinder. It is as under
A) Apply the parking brakes of dead loco by apply push button.
B) Lock the parking brakes in applied condition. C)Release the parking brake of the dead loco by manual operation of parking brake release handle on each of the four parking brake units. For manual brake release, first turn the release handle slightly clockwise and then pull till a sound of locking mechanism is heard. The parking brake units are fitted on the following wheels:
D)If some of the parking brake handles are defective and due to this if not possible to release manually, then release the same by manually pressing the “Release” Push Button of the latched solenoid valve no.30 on the pneumatic panel of the dead locomotive.
11).As parking brakes are locked in applied condition PB gauge will show 0 Kg/Cm2.
12).Double check the release of parking brakes of dead loco by moving the parking brake unit by hand.
A) Apply auto brakes (A9) in the working locomotive and check that loco brakes on both the locomotives are getting applied. Then release the auto brake in the working loco and check that loco brakes are getting released on both the locomotives. Rear locomotive (WAG-9 / WAP-5 dead) takes about 1 minute to release.
B) As a final check, run the coupled loco for about 500 metres and feel for any abnormal rise in temperature of wheels of dead loco and also check if at subsequent stop during journey.
C) Remember that in the dead locomotive, the loco brakes takes about 1 minute to release after auto brake application from the live loco. Hence after every auto brake application and release wait for adequate time (minimum 1 minute) for release of loco brakes in dead locomotive before resuming traction
13). Escorts accompanied dead locomotive should never put BL key in position ‘D’ and also strictly avoid energising the dead locomotive.
14). After reaching the destination, before detaching the working loco,
A) Unlock the application plunger of parking brake solenoid valve no. 30.
B) Press the release button of parking brake solenoid valve no. 30. This will charge parking brake line by 5 kg/cm2 .
C)Apply parking brakes on dead locomotive by application plunger of parking brake solenoid valve no. 30.
B) Hauling dead WAP5/WAG-9 locomotive fitted with E-70 brake pipe control system when attached next to leading working locomotive:
1. Switch off BLDJ and lower the pantograph of the loco to be sent as dead. Isolate the pantograph through panel isolating cock on pneumatic panel.
2. Switch off CEL as follows:
a) Operate BL-key from ‘D’ to ‘Off’ (wait for 2 sec.)
b) Operate BL-key from ‘Off’ to ‘C’ and wait until display screen, LSDJ, and UBA goes off.
c) It indicates that CE is get’ OFF’ and now rotate BL from ‘C’ to ‘OFF’. Switch off the ‘circuit breaker control circuit locomotive’ (112.1) in SB2 panel.
3. Couple the dead loco in rear of the working loco.
4. Put auto brake controller (A9) in “Neutral” position in both cabs of dead loco.
5. Put the direct brake controller (SA9) in “Release” position in both cabs of dead locomotive
6. Drain the Main and Aux. reservoirs of dead locomotive completely. After draining out, close the drain cock of main reservoir and aux. reservoir 7.If loco brake in the dead locomotive have not got released, which can be verified by observing the BC pressure gauge, then release the same in the following steps.
a) Manual handle of distributor valve at pneumatic panel should be operated manually to release control pressure. BC pressure shall automatically vent through D2 relay valve to release loco brakes.
b) In case residual BC pressure remains in brake cylinder line, the BC pressure should be released through bogie isolating cock of both bogies. Make bogie-isolating cocks in ‘Normal’ position after releasing the BC pressure
c) In the dead locomotive, ensure isolating cock position in the pneumatic panel as follows. (Towed dead):
8. Connect BP pipe of the dead loco to the BP pipe of working loco and open BP angle cock of both the locos. The aux. reservoir on dead locomotive will get charged from BP supply of the working locomotive. Check the BP pressure gauge in the cab of dead loco. It should show the same pressure as that of the live locomotive (In case of locos are to be attached on a train having twin pipe i.e. both BP and FP then FP of both the locos should also connected and its angle cock should be opened.)
9.Lock the parking brakes in applied condition. This procedure is safe to avoid brake binding and condensation of moisture in the parking brake cylinder. It is as under
a) Apply the parking brakes of dead loco by apply push button.
b) Lock the parking brakes in applied condition.
c) Release the parking brake of the dead loco by manual operation of parking brake release handle on each of the four parking brake units. For manual brake release, first turn the release handle slightly clockwise and then pull till a sound of locking mechanism is heard. The parking brake units are fitted on the following wheels:
d).If some of the parking brake handles are defective and due to this if not possible to release manually, then release the same by manually pressing the “Release” Push Button of the latched solenoid valve no.30 on the pneumatic panel of the dead locomotive.

12) Apply auto brakes (A9) in the working locomotive and check that loco brakes on both the locomotives are getting applied. Then release the auto brake in the working loco and check that loco brakes are getting released on both the locomotives. Rear locomotive (WAG-9 / WAP-5 dead) takes about 60 seconds to release.
13) As a final check, run the coupled loco for about 500 metres and feel for any abnormal rise in temperature of wheels of dead loco and also check if at subsequent stop during journey. 14) Remember that in the deal locomotive, the loco brakes takes about 60 seconds to release after auto brake application from the live loco. Hence after every auto brake application and release wait for adequate time (minimum 1 minute) for release of loco brakes in dead locomotive before resuming traction
15) Escorts accompanied dead locomotive should never put BL key in position ‘D’ and also strictly avoid to energise the dead locomotive.

C) Hauling dead locomotive fitted with IRAB-1/28LAV-1 brake system by WAP-5/WAG-9 locomotive
1. Set up the IRAB-1/28LAV-1 locomotives for hauling dead in normal condition.
2.Connect BP pipe of the dead loco to the BP pipes of working loco and open BP angle cock of both of loco and load side. The aux. reservoir on dead locomotive will get charged from BP supply. Check the BP pressure gauge in the cab of dead loco. It should show the same pressure as that of the live locomotive (In case of locos are to be attached on a train having twin pipe i.e. both BP and FP then FP of both the locos should also connected and its angle cock should be opened.)
3.Check the release of parking brakes/hand brakes of dead loco by moving the parking brake/hand brakes unit by hand and observing the clearance between the brake blocks/pads and the wheels wheel disc.
4.Apply auto brake (A9) in the working locomotive and check that loco brakes on both the locomotives are getting applied. Then release the auto brake in the working loco and check that loco brakes are getting released on both the locomotives.
5. As a final check, run the coupled loco for about 500 metres and feel for any abnormal rise in temperature of wheels of dead loco and also check if at subsequent stop during journey. 6. After reaching destination, before detaching the working loco, apply parking brake/hand brake on dead locomotive
