We have more than 20 years of experience in designing modular solutions, building flexible products, providing system and network integration, and engineering services for all types of train networks. We produce complete documentation, including product specifications, fault management plan, training materials, and user manuals.

Quester Tangent proactively reduces technical and contractual risks for rolling stock manufacturers by committing to deliver all aspects of the project scope. We have strong internal processes in place to ensure consistent design, production, integration, and on-time delivery of allocated scope.

We are an independent company with complete in-house electrical, mechanical, software, and system engineering capabilities, assisted by project management and manufacturing expertise. As your one-stop shop for train electronics, we excel at meeting our contract requirements on time and on budget.

Quester Tangent is a trusted partner of the rail transit industry and a leader in integrating innovative technology into train systems. We work with consultants and transit authorities by supporting them early on to clearly define their needs and advise them on their technology options before project tenders are released.

We stand behind our products for the train’s service lifecycle. On a pro rata basis, we will cover our support costs to provide our customers 20 years of service continuity for products delivered into new build, retrofit, and overhaul projects.

Quester Tangent maximizes the lifespan of its products and reduces the total cost of ownership. We provide our customers with annual reports to identify End-of-Life (EOL) concerns with our equipment and proactive notifications with a defined timeline and action plan for resolving EOL issues.

We have mature processes, industry-compliant products, and strong business practices backed by top-ranking project and supply chain quality audits. We drive operational expansion from the top down to ensure efficiency and growth. We hone our systems from the bottom up by embracing external and internal audits and feedback to increase customer and employee satisfaction.

Quester Tangent builds flexible products supported by a long-lasting service guarantee. We can easily support overhaul and retrofit projects by designing and delivering products that adapt to the form, fit, and function needs of our customers’ existing fleet, or to meet new and additional requirements.
