About Quester Tangent

Communication is key to any healthy relationship. Your trains have a lot to say and they need a good listener. The data is already being collected from your fleet; all you need is to start the conversation. That is where we come in.

Using our industry-leading technology and our full portfolio of capabilities and services, we deliver a complete suite of train electronics and software solutions in rail-robust packages that meet your fleet’s unique requirements.

No more guessing. No more trial and error. Let us get your trains talking!

Who we are

Quester Tangent is a Canadian company that has served international markets for more than 30 years with an innovative range of products and services. Our first market was acoustic seabed classification, involving capture and analysis of raw seabed data on international coast guard and navy vessels.

We eventually parlayed this expertise into train management systems in the early 1990s. We are now a leading manufacturer, supplier, and integrator of train electronics and software solutions for the passenger rail and locomotive industries in North America.

What we do

We offer flexible, modular, scalable electronic products to rail vehicle manufacturers and transit authorities that enable the efficient movement of people and goods. Each onboard and wayside product we design, manufacture, and support helps our customers increase operational efficiency, improve fleet availability, optimize on-time performance, and enhance passenger safety and comfort.

We have successfully delivered a broad spectrum of projects on time and on budget in North America, Korea, China, and Malaysia.
