Feature Highlight
Taking the railway application for example, Portwell is well aware of the complexity and strict regulations of railway management. We follow stringent rules and standards to design solutions for each application-specific use case.
Portwell offers railway embedded computing solutions for various settings including outdoor, indoor and on-board applications. For outdoor environments like wayside locations, our products support a wide temperature range and meet high-humidity requirements to operate reliably under extreme weather conditions/changes, and these products also provide multiple wireless communication interfaces to ensure continuous connection and communication; for on-board solutions, the locomotive power regulation is uniquely different from that for other applications, and our embedded computing systems are designed with anti-shock and anti-vibration protection. All of Portwell’s railway embedded computing solutions are designed with application-centric features to fulfil each customer’s needs and requirements.
EN 50155 / EN 50121 Compliance
The EN 50155 compliance covers electronic equipment used on rolling stock for railway applications, and the EN 50121 compliance covers electromagnetic compatibility. We also follow the JIS E 5006 standard of Japan, and the ARIMA Section11 of the United States according to customers’ requests.
Waterproof and Anti-Corrosion
To effectively prevent damage from harmful environmental conditions, from the normal outdoors to seaside, Portwell’s railway embedded computing solutions are designed with waterproof and anti-corrosion features, with the PCB even using conformal coating.
Wide Voltage Input
Portwell’s products provide 12V-36V and 72V-110V power input options. The power management is designed to comply with the railway regulations, and we work with each customer holistically, and have controlled every material/component starting from the design stage.
Anti-Shock and Anti-Vibration
The locomotive systems inevitably vibrate during operation. To minimize the impact, anti-shock and anti-vibration designs come as standard among the Portwell railway solutions. We design in the anti-shock and anti-vibration features with carefully selected and implemented connectors, cabling, memory and storage devices, from the component level all the way to the system level.
Wide Temperature Range
Portwell’s railway embedded computing solutions support a wide temperature range from -40°C to 70°C accommodating outdoor temperature fluctuations with operation stability and reliability.
Robust Connection
To safely ensure efficient and robust communication for all the connected devices in the environments where there are constant shocks and vibrations, we isolate every I/O feature on schematic and PCB layout designs, and adopt industrial-grade M12 connectors.

Use Cases
Bus Infotainment System
A bus infotainment system is one of the most effective communication methods to provide passengers with the information they need, should it be that to help them plan their trips and/or play content that appeals to their interests, such as news, weather, agency alerts and so on. For bus infotainment systems, how to maintain the stability of the power supply system and integrated power ignition signal status are the key design considerations. In this use case, the infotainment system was to be connected with the bus’s battery directly. We’ve fulfilled the customer’s requirements…

Locomotive Event Recorder
When a railway accident unfortunately happens, a locomotive event recorder often serves to provide critical data leading to the discovery of probable causes, as well as then to assist the investigators to reach insightful conclusions and recommendations from analyzing the data recorded within.
In the development of railway systems, we incorporate the CHMM (Crash-Hardened Memory Module) into the system with high-speed I/O interfaces to manage all information concurrently to ensure that all critical information…

Railway Level Crossing System
Safety has always been the most important topic in railway transportation; how to reduce level crossing accidents is essentially critical. At most crossings, the level crossing system activate warning signals shortly before the locomotive or train approaches, along with barriers to stop crossing until the locomotive or train passed. And as technologies advance, more “intelligence” could now be built into the level crossing system to enable greater safety…

Automated Border Control System (eGate)
Airport managements all over the world are increasingly adopting digital systems. In the recent past, it was primarily the customs enforcement officers responsible for inspecting travelers arriving in or departing from the country to ensure border safety. However, with rising labor costs, the automated border control system has emerged as an effective alternative. At customs checkpoints, the automated gate control system (eGate) identifies travelers’ biometric features. If no issue are detected, the system activates to open the gate, allowing the travelers to pass through quickly and safely. And when the COVID-19…
