To achieve this, Mantena uses an efficient maintenance system, which is in compliance with applicable laws, regulations, orders and instructions from authorities, while the necessary requirements from material owners, operators and end customers are followed up at the appropriate level.

An effective maintenance system means that all parts of the system, such as maintenance programs, processes, organization and infrastructure, are optimally coordinated to achieve the best possible delivery and utilization of available resources.

Freight Train Maintenance

As is the case for passenger traffic, modern railfreight transport places strong demands on safety and punctuality. This is why we focus on maintenance systems that keep us one step ahead.

Since we correct any potential errors and replace any worn parts during planned maintenance, we limit the possibility of unforeseen downtime.

In this way, we help shipping companies acheive daily operations that are more predictable and cost-effective.
