their management to achieve effective utilization and get the best results. An effective
operations control management, loco requirement and its monitoring, crew requirement
and their training are required for effective utilization of diesel locos. A diesel loco would
cater to the power requirement of several divisions and even on the adjoining railways.
Therefore, an effective Central Power Control Organization is required at the railway
headquarter to monitor and direct the movement of diesel locos between different
divisions in accordance with the requirement.

2.2 Organization – Railway Board level

2.2.1 With the increasing traffic requirement, the power requirements for each Railway

need a very close scrutiny so that the allotment is made to get the best operational
results, keeping in view the maintenance facilities available.

2.2.2 At the same time, as more and more diesel locos are put on the line, the workload of

utilizing these costly assets for the optimum return and coordination of diesel
operation between different railways would increase. Hence, there is need that
Director Mechanical Engineering Traction be assisted by a Joint Director and two Dy.
Directors, duly supported by three Assistant Directors. The organization chart is
given in para 1.1

of Chapter 1 of this manual.

2.2.3 This organization will be responsible for the following:

2.2.3.1 Allotment and distribution: The requirement of diesel locos of each railway

should be examined and the allotment made according to the priorities laid down.
Depending upon the traffic needs, it may also sometimes require transfer of diesel
locos from one zone to another for making necessary adjustments. Development
of the diesel loco maintenance facilities to meet the operational demand is also
required to be planned, commensurate with the projected diesel loco holding of
the Zonal Railway/Area.

2.2.3.2 Daily Outage: Monitor performance of different zonal railways with regard to

daily availability of locos, i.e., day to day diesel outage, particularly with regard
to locos of one zonal railway working on another railway, in accordance with the
directives and the quota fixed from time to time.

2.2.3.3 Ensuring reliable operation of the locos by monitoring day to day punctuality of

important mail/express train.

2.2.3.4 Analyzing failure of diesel locos online with regard to the reliability of their

performance.

2.2.3.5 Rendering assistance of material from DLW/DLMW and other railways to reduce

the ineffective period, where locos are held up for long duration.

2.2.3.6 Coordinating with RDSO/DLW/DLMW for sorting out major design/vendor

related issues, affecting reliability of locos.

2.2.3.7 Utilization of locos, i.e., Engine Kms/day/ engine “In use” and ‘ On Line’

2.2.4 Managing various issues related to Crew / loco Management.

2.2.5 Managing various issues related to Diesel Fuel and Lubricants.

2.3 Daily Outage: The outage of diesel locos for goods traffic would be fixed on the following

basis:

2.3.1 Total locos on line = N

2.3.2 Ineffective percentage = 0.10N (0.05N for HHP locos)

2.3.3 Locos in use = 0.90N (0.95N for HHP locos)

2.3.4 Mail/Express/Passenger Link=L

2.3.5 Spares for running maintenance = 10% of (0.90 N-L) (5% for HHP locos)

2.3.6 Outage =0.81N (0.9025 N for HHP locos), if L=Zero, otherwise as per the

calculation

2.4 Ineffective Position:

2.4.1 Ineffective position of diesel locos on each railway would also be watched daily to

maintain the maximum outage of diesel locos. If any locos are held up for long
duration, necessary assistance of material from DLW or other railways would be
rendered to reduce the ineffective percentage. The provision of ineffective towards
maintenance is 10% for the Alco locos (consisting approx. of 5% for heavy schedules
2% for POH and 3% for corrective maintenance, waiting for material etc.), other than
WDP1 & WDP3A for which ineffective prescribed is 12.5%. The same will be 5%
for HHP locos (consisting approx. of 3% for heavy schedules 1% for POH and 1%
for corrective maintenance, waiting for material etc.).

2.5 Zonal Railways: CME(O)/Dy.CME/O will be responsible for the following aspects of

diesel operation:

2.5.1 Planning and utilization of diesel locos to meet with the requirements of passenger,

goods and other services on the Railway.

2.5.2 Distribution of diesel locos between different divisions on the railway.

2.5.3 Ensure daily outage target of diesel locos from sheds and their distribution over

different divisions and railways.

2.5.4 Co-ordinate with other railways for diesel operations.

2.5.5 Watch daily utilization of diesel locos on each division and other railways.

2.5.6 Reduce detentions to diesel locos on line.

2.5.7 Plan servicing and scheduling facilities for diesel locos keeping in view the operating

requirements.

2.5.8 Ensure timely dispatch of locos to base sheds for undergoing prescribed maintenance

schedule (locos not to run overdue schedule)

2.5.9 Ensure reliability of diesel locos in operation. Keep a check on daily position of

diesel loco failures and its repercussions on punctuality of coaching and goods
operation. Analyze cases of loco failures and take remedial measures.

2.5.10 Timely Movement of disabled diesel locos.

2.5.11 Induction/Promotional and Refresher Training of running staff for diesel operation.

2.5.12 Keep a check on crew link for passenger services and 10 hours duty working for

goods services.

locos.

2.5.14 Ensuring fuel economy in operation.

2.5.15 Co-ordinate, upkeep and maintenance of all ARTs/SPARTs, ARMVs/SPARMVs and

Break Down Cranes available in the Zone.

2.6 Central Power Control Organization: A central Power Control Organization at the

Railway Headquarters shall be provided for exercising the necessary control on diesel
operation. This will be staffed by a Chief Power Controller, with two Power Controllers in
each shift to function round the clock. An assistant (Group C) and a Group D staff shall
also be provided in each shift to the shift Power Controllers for maintaining the various
records, distributing daily position, various documents, etc. to the HQ officers. However,
this scale of organization can be suitably enhanced depending on the local conditions, with
the approval of CME. The Central Power Control will be responsible for:

2.6.1 Maintaining close liaison between the shed and division regarding the power

distribution.

2.6.2 Monitoring availability of locos from each shed for traffic on 4-hourly basis.

2.6.3 Continuous collection of factual data of loco position on each division on 4- hourly

basis.
