Ans: Classification: 1) Running repairs – carried out when the equipment has actually failed. 

2) Trouble shooting – involves rectification of the defects by making temporary repair so that equipment is made get going on. 

3) Preventive maintenance - advance actions have to be taken to ward off the future failure. 

Factors on which ideal maintenance jugged : 

1) Reliability of locomotive 

2) Availability of locomotive 

3) Overall cost of loco maintenance 

Means to improve reliability Proper inspection, proper method of trouble shooting & repairs , proper technical investigation , suitable repair facilities 

OR 

Means to improve availability Inspection schedule , co-ordination between maintenance and operating staff , coordination of work at shed , availability of standby and quality spares
