EN 50155 compliant Integrated Solutions for
Passenger Information System on Refurbish Trains

  • Upgrading passenger information systems on aging trains is subject to many limitations, including space constraints, wiring difficulties, and other costs. Moxa’s ioPAC 8020 is an EN 50155 compliant RTU controller with a rich selection of serial, I/O, and Ethernet ports in a compact housing designed for space-constrained onboard environments. It enables the convergence of multiple subsystems, so the passenger information system can integrate the track location data, PA system, LED displays, and train information to give passengers both audio and visual update about the status of the train.

    The integrated ioPAC RTU controller and ioLogik E1500 railway remote I/O can also collect crucial status information about the train’s doors, HVAC system, compressors, breaks, and lights. This information can help maintenance engineers to identify potential problems in a timely manner, which not only reduces maintenance effort, but also provides better availability of service.

Technical Challenges for Operators and Integrators of Refurbished Trains

To achieve the full integration of all onboard passenger information systems, train operators need an onboard controller that reports the status of train doors, HVACs, compressors, brakes, lights, and other key parts of the train’s infrastructure. These reports must be made in a way that helps maintenance engineers identify potential problems in a timely manner, not only to reduce maintenance effort, but also to provide better overall availability and a higher quality of service. For refurbished trains, system upgrades are usually done by system integrators who specialize in reusing or repurposing as many of the existing legacy systems as possible—to maximize both savings and interoperability

Integrated control and management platform:

Integration control and management platform

The ioPAC RTU controller not only combines serial, I/O, and Ethernet interfaces into a single device, it also supports the C/C++ and IEC 61131-3 programming languages and ready-to-run services, including data logging and email alarms. Packing all of these great features into one device simplifies system development, reduces the amount of maintenance required, and improves service and network reliability.


Efficient Automatic Carriage Sequencing (ACS):

Older train systems run on a daisy-chain network topology based on either CANbus or RS-485. When it comes time to switch to an IP-based network on the refurbished train, duplicating the automatic carriage sequencing function is not easy to do. Moxa gets around this challenge by building support for ACS functions directly into the new IP network, greatly reducing the effort required by the system integrator.

2-wire Ethernet technology:

2-wire Ethernet technology:
Limited number of coupler poles

A refurbished train may only have a limited number of coupler poles, even when the entire existing network, which could include wiring that supported RS-485, CANbus, and other technologies, is removed. Moxa’s 2-wire Ethernet technology offers system integrators the option to upgrade to an IP network based on the existing system, thereby further reducing the cost and effort associated with other applications. Furthermore, 2-wire Ethernet supports Ethernet bypass functionality, ensuring that the Ethernet backbone is still available even when one carriage shuts down.
