Teldat Rolling Stock Equipment & Solutions

Maintaining secure, high-performance communications in rail rolling stock with harsh environments is challenging. Finding a supplier with the right products and expertise is essential.

Understanding Rolling Stock digitalization

Train operators can use a rolling stock digitalization strategy to differentiate their offering in an ever more competitive public transport market. The right digitalization technology will attract more customers by offering an enhanced passenger experience. It can also reduce costs by improving operational and maintenance efficiencies.

This digitalization depends heavily on reliable, secure ground to train communications, to avoid unplanned train stops, associated costs and reputation damage. Reliability starts with multi-WWAN capability – 4G, 5G, Wi-Fi trackside, Satellite – plus redundant backup connections to provide high availability that prevents service interruption. Intelligent networking using SDWAN technology allows easy, remote WAN management.

These factors assure reliable connectivity even in challenging environments; large vehicles packing an average 347 passengers moving rapidly through low-coverage areas. Security is achieved by encrypting traffic, with threat detection and firewalls in place. Operators should also set up suitable navigation and internet usage policies. But rolling stock digitalization also extends to onboard routing and access point equipment providing Wi-Fi services to the train’s high density of passengers. Network Access Control (NAC) must be used to control user access and block unauthorized logins. Connectivity must also be provided for IoT devices via WLAN, Bluetooth, or Bluetooth LE. While providing this functionality, all onboard communications equipment must comply with at least the minimum mandatory railway certification standards.

Security is as important on the train as outside; the SDWAN should employ point to point encrypted comms to prevent train network infrastructure attacks, whether from WLAN interception, connection of non-authorized devices or equipment to the network, unwanted traffic propagation, or malware downloads. These events, plus unwanted web page access, hackers penetrating the network, or virus propagation into connected passenger devices all negatively impact the train operator’s reputation.Digitalization also helps physical security enforcement, through CCTV, train ticket control, people access control and counting, and facial recognition.

Onboard security and comfort can be further boosted by IoT deployments; these can collect data not previously available to operators. Once collected, this data can be automatically processed using artificial intelligence (AI) to optimize decision-making. Operational efficiency can be increased by using proactive maintenance, which can reduce costs, improve quality of service and customer satisfaction. Passenger experience is also directly enhanced through better air quality, temperature, and humidity control.

If technical problems do arise, digitalization enables fast, immediate troubleshooting. Network usage and status, train to ground coverage and communication status, and equipment maintenance status all become visible.

Train to ground communications:

Teldat train to ground communications platforms are the cornerstone of rolling stock digitalization, with multi-WWAN communications provided by ruggedized rail routers, all of which are SDWAN compatible. An existing fleet can be upgraded to 5G simply by adding a compact device.

Backup and resilience are guaranteed by the multi-sim option, load balancing and aggregation, with options included in the device OS. The equipment is tested in rough environments, with high speeds of 300 km/h, and extended temperatures of -20 °C to 70 °C.

GPS provides awareness of train location, while CCTV and ticket control systems can be connected for digitalization of physical security enforcement.

Onboard communications:

Best in class onboard communications solutions manage passenger wellbeing during their journey. An SD-WAN-compatible Wi-Fi 6 access point (AP) handles high user density, with high throughput guaranteed.

Security at the highest level is assured by integrating the latest WPA3 security standard onto the AP. User experience is optimized through simultaneous transmission in the 2,4 GHz band (to 1148 Mb/s) and 5 GHz (to 2402 Mb/s) in the 802.11ax (Wi-Fi 6) standard.

The AP also integrates Bluetooth/BLE for IoT device connection and data collection. Some devices monitor passenger environment parameters including CO2, temperature, and humidity. Others measure maintenance parameters such as door vibration.

H2-Rail platform

Teldat’s H2-Rail Router and new APR2044ax Wi-Fi 6 Access Point make a perfect connectivity solution for railway scenarios. It is a Gateway for multiple onboard services, including CCTV, ticketing, passenger information systems, Internet services, and IoT equipment. It contributes to WAN resilience through multi-WWAN fallback, load-balancing and aggregation, plus advanced link monitoring.

Its dual LTE modules and dual Ethernet port allows easy integration into existing installations, and it can withstand harsh rail environments. With GPS-dependent configuration, it features advanced troubleshooting and management.

APR2044ax Wi-Fi 6 Access Point

With Wi-Fi 6, the APR2044ax brings new performance levels to crowded rail scenarios. It swaps easily with the previous APR222ac because they have the same housing dimensions, includes Bluetooth for IoT applications, and matches perfectly with H2-Rail and 5Ge Rail. It can be managed via the Teldat WLAN controller or Be.SDX cloud solution.

With the latest WPA3 security standard, the AP offers the highest security level. It achieves high efficiency by combining Wi-Fi 6 with MU-MIMO 4x4 and other technologies for optimal spectrum use. It transmits simultaneously in the 2,4 GHz band to 1148 Mb/s and 5 GHz to 2402 Mb/s in the 802.11ax standard.

5Ge Rail

The 5Ge-Rail adds 5G comms to the H2-Rail, or operates standalone. Together with the APR2044ax, it is perfect for rail connectivity. Like H2-Rail, it is a router for multiple onboard services; it is low-cost to install, and easy to integrate due to its dual Ethernet ports.

Due to its small size, it can be installed near the antenna, reducing wiring and costs, and increasing coverage. Susceptibility to electric noise is also reduced, and it provides a no loss antenna signal.

All railway mandatory certifications are included. The device provides an NMEA GPS signal and relay control signals.

be.IoT Platform

This cloud-based platform collects IoT data to enhance the passenger experience, while allowing operators to manage devices. The data can also be analyzed using AI and machine learning to aid decision-making.

Indoor Air Quality (IAQ) is monitored for passenger comfort reading CO2 concentration, temperature, and humidity; the Be.IoT alert CO2 system with regular ventilation reduces virus transmission risk.

Be.IoT aids proactive maintenance for doors and other rail components by checking for abnormal vibration levels, and uses a data model to provide early warnings.

Quality of service and customer satisfaction are improved, while costs are cut.
