Conclusions: 31.03.71 DME KX states:  No apparent fault at the time but subsequent checking in
traffic revealed that the traction motor circuits were out of balance - the loco was taken out of traffic
for Main Works rectification on 16.03.71. Please see correspondence regarding false wheelslip
indication on locomotives No.s 9015 & 9018 after release from Works. I would suggest that a voltage
check across the wheelslip relays when the locomotive undergoes its load test run after a Classified
Repair would be desirable.

19,250 miles since last classified repair (13.02.71).
Conclusions: 05.05.71 DME KX states: There have been three cases recently of defective horn valves
on class 55 locomotives. See also casualties for 9003 (18.02.71) and 9001 (21.04.71). Perhaps some
investigation into the Works repair and or overhaul procedure would be desirable, with particular
reference to the rubber seating washers (complete valve subsequently changed at Finsbury Park).

Casualty report states: false wheelslip indication at 80mph and above.
32,800 miles since last classified repair (13.02.71).
Conclusions: 26.05.71 DME KX states: Please see my letter of 19th March and the CM&EE's reply
of 26th April regarding false wheelslip indications experienced with this locomotive and results of
special shopping. Resetting of the wheelslip relay has now apparently overcome this trouble, but it
is obvious that the out of balance voltage at high speeds is greater than is desirable. In view of the
amount of trouble experienced recently with false wheelslip indications on this class of locomotive
I consider that a check of out of balance voltages, at 100mph with warm machines and the pick up
voltage of wheelslip relays, should be made before a locomotive is released to traffic after Classified
Repair.
Doncaster TMD.
Repairs - could not fault, locomotive to be accompanied in traffic by CM&EE Inspector on 1A29.

Casualty report states: engine cutting out - intermittent power earth fault on No.2 end cubicle bus
bar from reverser to 4, 5 & 6 traction motor contactor fouling framing of the cubicle (due to the
vertical length of the bus bar being bent).
44,060 miles since last classified repair (13.02.71).
Conclusions: 22.07.71 DME KX states: I am confident that the bus bar could not have been bent
accidentally whilst in situ as its cross section is too great. I can only assume therefore, that it had
not been set correctly by Main Works, although I appreciate that the locomotive had been in service
over three months before the defect showed itself.
Gateshead TMD.
Repairs - bus bar straightened and reinsulated.

Casualty report states: loss of power - load regulator finger contacts burnt.
95,920 miles since last classified repair (13.02.71).
Conclusions: 26.08.71 DME KX states: The history of this locomotive shows several instances of
defects in No.1 main generator field circuit, but no root cause has been established. On 24th August
the GFG1 contactor was found to be badly burnt and on 17th September the locomotive was checked
in service by the CM&EE representative Mr Edwards who reported an open circuit on R33 stud.
Mr Edwards along with my staff, however, subsequently checked the locomotive in Depot but could
not fault it.

Casualty report states: Driver reported compressors stopped, air lost and brakes applied.
130,980 miles since last classified repair (13.02.71).
Conclusions: 24.01.72 DME KX states: I can only assume that when the locomotive failed No.1 engine
had in fact shut down and due to some intermittent defect in the electrical control circuits 'AGC3' did
not close to allow No.1 compressor (vacuum braked train) to run from No.2 auxiliary generator. If the
driver had either used the fuel priming pump button for No.1 engine and attempted to restart that, or
the compressor emergency switch he would in all probability have been able to regain air pressure.
There has been no further trouble with this locomotive with regard to either compressors or fuel system
air locking.
20 - York TMD.
Repairs - unable to fault compressors or compressor circuit but unable to start No.1 engine due to fuel
system air locked (No.1 engine not running when locomotive arrived on York Depot). No.1 engine fuel
system primed, engine restarted, run up and tested.

136,170 miles since last classified repair (13.02.71).
Conclusions: 30.12.71 DME KX states: locomotive log book checked and no record of servicing
at Haymarket - appears to be mismanagement in Scottish Region.

Casualty report states: No.1 engine shutting down - fuel starvation due to fuel aeration.
Conclusions: 03.12.71 DME KX states: locomotive No.1516 was diagrammed for this train, but due
to a series of mishaps 1516 was taken to work 1A11 08:10 Newcastle - King's Cross. 9015 had been
fuelled with 700 gallons after arriving on the depot at 07:45 and it was after the fuelling that the above
