Critical component maintenance management

Trimble® E2M rail engineering critical component and maintenance management system, manages and tracks critical components, streamlines parts and materials usage, optimizes resources, and procurement.

Maintain, manage, and track critical components to optimize lifespan

Designed by rail experts to track maintenance of critical components

Designed specifically for the rail sector Trimble E2M manages and tracks critical components to streamline rolling stock maintenance management. It allows rail organizations to maintain and manage the cost effectiveness of rolling stock by improving component reliability, resource and capacity planning, and work utilization while reducing operating costs. Managing critical components, such as expensive and safety critical wheelsets and brakes, with Trimble E2M enables the effective planning of maintenance across engineering depots, resources, and material requirements.

Management and traceability of critical components

The E2M system allows rail operators to control the preventative and corrective maintenance of critical components to maximize and extend component life. E2M gives a single view to aid the management of components, stock, rolling stock assets, and suppliers, and efficiently handles warranty management. It interfaces to existing systems for end-to-end streamlined maintenance workflows and for efficient future maintenance planning. Unifying maintenance management in Trimble E2M minimizes errors as all stakeholders work with the same baseline system, rules, and related actions.

Streamlined tracking of critical component maintenance data and work status

With data consolidated in E2M, maintenance work can be carried out efficiently and with a complete trail of what work has been done and when. As well as being a repository for vast quantities of measurement data the Trimble E2M rules engine automatically processes large datasets to maximize data usage. User-defined rules trigger action when maintenance is required. Using the Trimble E2M system improves operational efficiency, reduces costs, and gives better visibility into operations to maximize productivity.

Traceable status of critical components maintenance

Clear overview of maintenance work status for critical components such as wheelsets and brakes. Interfaces with existing systems for streamlined end-to-end workflows.

Reduce and streamline labor costs

Identify and reduce repeat defects by identifying the true cause of the defect minimizing costly rework. Monitor defect history over time against each component to prevent repeat defects making rolling stock unavailable for service.

Optimize maintenance planning

Plan maintenance to identify opportunities and not exceed engineering depot resource capacities. Ensure all components maintained on time in accordance with the maintenance schedule.

Increase component and rolling stock asset availability

Ensure component and rolling stock availability by monitoring usage over time with Trimble E2M. Automatically define re-order levels against each part to ensure stock levels meet demand. Control centralized procurement by defining central stores to manage stock for satellite stores.

More successful warranty claims

Every warranty claim raised in E2M shows the fitment and receipt date, serial number, and complete history ensuring fewer contested warranty claims.

Improve safety

Effective control of safety critical work minimizes safety issues by driving reliability and mitigating failures.

Flexible mobile workflows

Trimble E2M Workshop app puts E2M functionality in the hands of depot workforce wherever they need to be. The Trimble E2M Defect Reporting app means staff can send reports direct to the Trimble E2M system from a phone or tablet.
