30207 Test and Trials
The observations regarding tests and trials should be carefully documented for the benefit of improving specifications or modifications to inspection schedules. The necessary documents should be centralized and kept in the PPO.
30208 Materials Management
1. This subject is dealt in detail in Volume I. A few relevant items are being mentioned here.
A. The various components - sub-assemblies and spare parts shall be purchased from the original/ approved supplier of equipment. Railway may however make out a compendium of approved suppliers for each item/equipment, based on RDSO's/production unit's list. Any variation from the same shall only be permitted personally by Chief Electrical Engineer.
B. For bringing in new suppliers in the compendium of approved suppliers, CEE may personally authorise use of untried and untested equipment for field trials. Special care is needed while approving any new make and type of brushes for traction motors.
C. Storage of Rubber Components
Storage procedures in general for any type of rubber components are given below: -
i) Rubber components should be kept away from direct sun light preferably in dark place. Direct sunlight causes much faster degradation of the rubber components.
ii) They should be stored in a cool place as far as practicable, preferably below 30°C.
iii) The humidity of the storage condition should not be such that condensation of moisture takes place on the surface of the material.
iv) In the vicinity of these materials, any loose electrical connections should be avoided, as these cause production of ozone which adversely affects rubber.
v) Rubber materials should be stored away from contact with certain materials particularly those containing copper and manganese which act as poisoning agents, aiding their fast degradation.
vi) Under no circumstances rubber materials should be stressed during storage The portions under stress undergo deformations with permanent set leading to degradation. The materials should be stacked in such a way so that any super-imposed stresses are substantially avoided.
vii) Any contact with grease or oil should be avoided as these cause swelling, softening and deterioration of rubber materials.
viii) French chalk should liberally be applied on the surface of rubber materials.
ix) Great care is to be exercised so that the material is used in the order of their receipt in the stores The rubber material whether under storage or in use continues to deteriorate. The only difference is that under service condition, deterioration is much faster. Every moment of storing is at the cost of useful life and prolonged storage of the material may render it unserviceable due to progressive deterioration.
30209 Demarcation of Responsibility between Sr. DEE (RS), DEE and AEEs
The DEE / AEE (maintenance) will be responsible for day to day activities in the shed including unscheduled attentions and scheduled inspections He will be particularly responsible for induction of any new type of stock in the shed and ensure that the maintenance schedule for such stock are finalized in the shortest possible time.
The Sr. DEE will in addition concern himself with the broader aspects of work and forward planning such as watch-out for organizational shortcomings, indenting and progressing the procurement of forward delivery spares, maintaining a close watch on the functioning of the PPO and above all, exercising vigilant technical control over unusual occurrences, recurring failures and unscheduled booking of locos to the shed and shall be in close liaison with Sr DEE (OP)
30210 Job Cards
For each loco/EMU received in a shed for scheduled or unscheduled attention, the PPO will issue a job card in proforma 2.01 to each section incorporating the following:
a) The nature of inspection (IA, IB etc.). Refer to chapters III and IV.
b) Additional items of work to be carried out on the loco/EMU by the section, based on booked defects, pre-inspection of the loco or planned modification.
c) The time by which the loco/EMU is required to be released.
Based on his own inspection, if the Section Chargeman finds that any items in addition to those mentioned by PPO are required to be attended to, he will get such work approved by TF (M) and get the additional items also entered in the job card by PPO. The job card will thus contain a complete record of all work done on a loco during its visit to the shed. When the work is completed, the Section Chargeman will sign the job card indicating the time of completion of the work and the names of the workers. The loco/EMU should be offered by the PPO for final inspection by El only after job cards from all sections have been received back duly signed by the respective Chargeman

30212 Modification of Designs for Rolling Stock
Railways should not adopt any new design or modify the existing approved designs except for trials, without the prior approval of RDSO.
Procedure for Initiating and Progressing Modifications
1. One shed which has the bulk of the holdings of a particular class of loco / EMU will be nominated by the RDSO, in consultation with the Railway, as the parent shed for that class of loco /EMU.
2. Each Railway will continue to tackle operating and maintenance problems as hitherto, but will also furnish complete particulars of all problems and failures on each class of loco /EMU to the corresponding parent shed and RDSO together with the modifications evolved by it and further suggestions, if any.
3. The nominated parent shed will then collate all the information in regard to each type of failure, study the merits of the different improvements suggested from all angles and submit recommendations to the CEE of the Railways, giving, full particulars of the most satisfactory improvements / modifications after they have been actually tried out in service and found feasible. When any defect is found to be intractable and expert investigation is necessary, a comprehensive note on the subject should be prepared and submitted by the parent shed to the Headquarters Office. CEE will arrange to forward the considered recommendations to RDSO.
4. The recommendations received from the parent Railway will be subjected to a further scrutiny and analysis by the different wings of the RDSO after which final instructions regarding the standard approved method of modification / improvement will be issued to all concerned, giving an identification serial number to each with full details and drawings required for carrying it out.
5. On receipt of the instructions from RDSO, each user Railway will arrange to carry out the modifications on priority on locomotives / EMUs until the work is completed in all locomotives/EMUs. Progress of implementation of the modifications will be regularly sent to CEE's office by each shed and CEE's office in turn will send a quarterly report of progress to RDSO.
30213 Records and Register to be Maintained in LOCO / EMU Sheds
Particulars of some of the basic records to be maintained by sheds are given below:
1. History Book - For each electric locomotive / motor coach, a History Book should be maintained in the loco / EMU shed by the Planning and Progress Office, (PPO). The History Book should have separate pages allotted for recording the items listed below in the proforma shown against each
a) Pre-commissioning details.
i) Contract or order number against which received.
ii) Date of despatch/shipment.
iii) Date of receipt by the Railway.
iv) Date put into service.
v) Particulars of tests and trials carried out and reference to reports on these
vi) Particulars and serial number of major equipment initially provided
vii) Particulars of any major defects rectified or modifications carried out prior to commissioning. b) Defects and failures during the Guarantee period: 
i) Changes in Main Equipments:
PPO should record particulars of replacement of complete units of main equipment such as Traction Motors, Transformer, Rectifier, Pantograph etc., together with serial numbers of the original and substituted items and reasons for replacement.
k) Record of mechanical clearances with bearing on safety.
This History Book should be sent along with the loco/EMU to the workshop when the loco / EMU is booked for POH for heavy repairs and should be received back with the loco /EMU. The workshop should enter details of work done and modifications, if any carried out.
2. Equipment Cards: In the case of major items such as traction motors, transformers, rectifiers, circuit breakers, pantographs, tap-changers, auxiliary machines, bogies, wheels, etc. 'Equipment Card' should be maintained in the shed by the PPO so as to have for ready reference the history of the equipment. Individual Cards should be maintained for each unit of major equipment and the individual cards may be stored grouping them either equipment wise or loco-wise as convenient. The Equipment Cards should contain details as shown below: 
30214 Unusual Occurrence Reports
A report indicating failure, withdrawal and any other technical abnormality in locomotive/EMU observed on line is called Unusual Occurrence Report (UOR). This should be made in each case recording in full detail as to what has actually happened and what steps should be taken in future to avoid recurrence.
While suitable proforma may be laid down by each Railway to suit local requirements, the UORs should basically contain the following details:
i) Report of Driver / Motorman detailing all his observations, together with remarks of TF(R) and Officers incharge of operation.
ii) Observations made by Maintenance Organization i.e. Technical Investigation Section, Maintenance Foreman and AEE/DEE (RS). A sample proforma is appended (Proforma 2.02).
UORs should be serially numbered for each calendar year to identify the homing shed, class of loco and serial number of the occurrence for the class of loco /EMU during the year e.g. TATA/WAG4/3/90. A copy of all UORs should be forwarded to CEE's office periodically.
30215 Periodical Review Information
Each homing shed should maintain requisite records and compile the following statistical information for each month. While the report on availability and reliability of the locomotive should be submitted to CEE every month, the report on the cost of repairs and maintenance should be submitted quarterly.
