Trains have a service life that is 10 to 20 times longer than most high-tech electronics products. As a result, today’s fleets are embedded with a plethora of network types and technologies. Networks can range from simple, custom, isolated networks with low-bandwidth, to complex, standardized, high-bandwidth networks that are shared by all modern train systems.
With advances in vehicle technology, new trains are more data driven. Video surveillance, passenger information systems, health monitoring, and other applications place high demand on train communication networks. And, expectations for managing and transmitting data quickly and securely have increased dramatically.
More than ever, fleet operators and rail vehicle manufacturers need companies with an in-depth understanding of train communication networks to provide strong integration and increase compatibility with older fleets.
Quester Tangent has that in-depth expertise—and the experience to deliver.
At Quester Tangent, we have been leading the way in delivering fully customized train communication network solutions for new and modernization projects for more than 20 years.
Developed with technology that is expandable, configurable, and adaptable to fleet operator needs, TrainWise® Communication Networks enable the integrated use of multiple wired and wireless products—including onboard Powerline, Ethernet, LonWorks, standard RS232, and RS422.
And, it all complies with relevant standards and comes with complete interface-control documents for lasting peace of mind.
Quester Tangent provides a wide variety of equipment and support for trains operating with a mixture of data networks and analog and frequency signals. This example shows how our control and monitoring products, Event Recorder, and communications systems work seamlessly with a broad range of onboard network and signal architectures.
Quester Tangent has expertise in the design and implementation of state-of-the-art network systems. This figure shows how we provide robust, fault-tolerant network solutions based on complex topologies involving train, consist, and train-to-wayside communication.
Quester Tangent supports numerous custom and standardized protocols for on-train and wayside networks.
