4 reasons to adopt oil analysis in railway equipment


The predictive maintenance of railway assets should happen frequently and meticulously. This is because the machines and the railway equipment, in general, carry a great amount of loads for long stretches. If any mechanical failure occurs, it can cause great damage to companies. As for example, delay in deliveries and loss of products loaded.

For companies to avoid irreparable problems like these, the indication is to invest in oil analysis . This technique assists in the detection of early wear symptoms components of locomotives and other railway equipment. In addition, it helps to understand the particularities of wear generated by the friction between the metal parts.

Oil analysis allows accurate analysis of the lubricant in the laboratory in a timely manner so that the information can be useful to the railway maintenance team.   Preventive maintenance is a way to increase equipment life simply by good management.

Check out some of the benefits of performing oil analysis in rail equipment correctly:

Lower maintenance cost

Chemical and physical analyzes of oil samples taken from a locomotive engine may indicate the condition wear of such railway equipment and other components, such as drive or hydraulic systems. In addition, other types of oil analysis such as testing for the presence of water or other contaminants in locomotive engines provide additional indication of engine condition and any other related mechanical failure. With this, it is possible to repair the problems before the defects become worse and generate damages for both the companies that transport and their customers.

Long service life

With oil analysis, it is possible to identify the need for filter and oil changes. In this way, the equipment is kept in good working condition without abnormalities. This will positively impact the life of the railway equipment. By adopting the oil analysis in preventive maintenance, it may contain the loss of any machine or component of the engine system due to some undetected or prevented failure, in addition to causing the locomotive not to be damaged by poor maintenance management .

Greater availability

With the oil analysis of the railway equipment, the assets will be less susceptible to failures and, consequently, to be paralyzed. In this way, companies can rely on their locomotives running efficiently for longer, presenting fewer problems or defects.

Lubricant saving

Oil is used in locomotives as a lubricant to reduce friction between moving parts of a mechanical system. This fluid is considered pure because it is usually the first item to be added to the engine of a railway equipment. However, over time, the chemical corrosion of the engine causes the oil to be contaminated. Analysis of the oil in these situations causes the lubricant to be replaced at the optimum time. Neither prior to its standard use nor after its stated durability.


Oil analysis is one of the main predictive maintenance tools for companies that use rail equipment in their operations. With a precise diagnosis from the oil analysis in hand, your company’s maintenance team will be able to identify errors more quickly. In addition to anticipating problems, and thus avoid compromising performance and the quality of service offered.
