Traction Motors are a safety critical item on all locomotives and there is a responsibility on train operators and owners to maintain their motors to a sufficient level whereby they continue to operate in a safe and reliable manner.
However, some owners / operators try to lengthen the time / distance between maintenance intervals to stretch their budgets further.
Parts that are used in motors only have a limited life-span, no matter who they are made by. The better the materials used, the longer the motors will last for, but a time does come when even the best materials wear out.
This can lead to catastrophic failures in motors with a complete breakdown on track with further damage caused to Stators, Wheel Sets, Gearboxes & Pinions.
Is it really worth it trying to lengthen intervals between maintenance to save the cost of a regular overhaul, and end up costing your business substantially more when motors get seriously damaged?
