Supply, Modernization and/or Manufacture for Mass Transportation Industry

We know that non-conforming services, products and production can be costly, time-consuming and just generally frustrating. RLC with its partnerships provides rapid and cost-efficient modernization solutions from engineering support of obsolete systems, standardizing through multiple revisions, short production runs for equipment integration and installation.

RLC works to develop proof of concept or prototyping to validate on-board vehicle systems used for FAI, Pilot to Production in mass transit. What we will need:

  • Size of Pilot/Production Run
  • Delivery and Turn-Around Time Requirements
  • OEM Drawings and Schematics
  • Bill of Materials (complete with part numbers and descriptions) and/or existing supply chain information
  • Minimum Standard Required
  • Required Test Procedures
  • Sample Assembly (if possible)

RLC places a high priority on our testing and measurement process. RLC will develop a test strategy with you as part of our service; all equipment is calibrated and tracked as identified in our quality program.

By having a history of specializing in modernization and component level repair we understand the need of control systems to support the design of custom test fixtures to dynamically test and validate all equipment we work on. This is supported by documentation as part of individual quality control/assurance programs ultimately leading to customer satisfaction.

We track all information for conformity to ensure consistency with the work we perform. We work with our partners to ensure that quality and timely performance is tracked and maintained at all times.
