The equipment for construction of industrial Ethernet networks for rail systems (switches, wireless access points, 3G / 4G routers, interface converters) must fully compliant with the requirement of EN50155, which means resistance to factors such as shock, vibration, altitude, temperature, humidity and power surges.
Railway Automation/EN50155 Certified
Railway transportation systems are vital in many countries and can bring rapid economic growth to an entire country. With such high importance of railway transportation systems, dependable information management of railway traffic is absolutely necessary, calling for the need of rugged network capable of handling massive real-time traffic information accurately without interruptions. It is not easy, however, to sustain reliable network service in such a high-speed moving platform of high-speed railway, since data can be affected by the train’s fast speed and associated vibrations, plus strong interferences on and off the train.
To meet the rising demand of TCN (train communication network), ORing, with industry-leading expertise of industrial networking, presents the EN50155-certified (and EN50121-certified) industrial-grade Transporter Series products for the tough applications of TCN. Thus far, ORing already has EN50155 Ethernet switches, EN50155 wireless access points, and EN50155 wireless cellular VPN routers, as the development of more EN50155 products on the way. With ORing products, automation applications on the train, along with network communications between the train and the train stations, are now simpler, much faster, more secure, and more reliable. An example of ORing industrial railway automation success story is in

Railway and Rolling Stock
• Current situation of Surveillance industry
With the progress of technology, railway transportation service is upgrading and diversifying. At the same time, the traditional railway communication – CCTV – is confronting limitations. On the other hand, IP surveillance nowadays becomes the main stream of the market because of its network function, flexibility and diversified service. IP surveillance not only breaks through the traditional barriers, but also enhances railway transportation security of with the full-scale integrated system of computer, communication and other equipment.
• IP surveillance
For intelligent applications, it displays service condition and fully implements security protection. Therefore, IP surveillance successfully reduces the occurrence of dangerous condition and accidents. In the control center, staff can monitor both the passengers and equipment all the time; moreover, they can transmit the high quality data timely and storage the digital signals in Cloud Computing. Through the networking signals, IP surveillance offers entertainment services to passengers, making the trip more comfortable and suits different needs.
• The reliable ORing product- TPS-3082GT-M12-BP1
It offers 8 sets of PoE ports based on IEEE 802.3af standard with M12 connectors, each of the ports supports 15.4 Watts of 48VDC power input. And its 2 gigabit ports offer Bypass function, which help network signals passing over the Ethernet switches under the power down condition.

Applications for ORing Railway Surveillance System TRA "Smiling Train" & MRT "Wenhu Line"
Background Introduction
With the increasing public awareness of the security issues on mass transportation systems, ORing Industrial Networking Corp has released series of industrial Ethernet switches that target at railway applications. Products such as TES-250-M12 and TPS-3082GT-M12-BP1 have been successfully applied to Taiwan Railway Association’s (TRA) Smiling Train as well as Taipei Mass Rapid Transit’s (MRT) Wenhu Line, providing passengers with a whole new travelling experience.
TRA’s six-star EMU800 Smiling Train has been officially launched earlier this month (2014.01.02, Taipei Times). This new commuter train purchased from Japan has not only offered economic ticket price, but shorten the travel time while considerately create cozy atmosphere and seats for passengers traveling on this train.
Known as the “smiling train,” the locomotive of the train is decorated with a yellow line resembling a crescent moon on the front. Both Smiling Train and Wenhu Line are embedded with ORing’s Ethernet applications—EN50155 Managed Ethernet Switches that are designed specifically for railway applications. These applications operate with double redundancy; O-Ring & Hardware Bypass, minimizing the recovery time for 250 machines to less than 10ms when the internet shuts off. With such advantage, ORing’s Etherent switches ensure passengers with best guarantee on commuting security.
Projects Details
The first success story begins with TRA’s Smiling Train. Each cabin of EMU800 Smiling Train is embedded with ORing’s TES-250-M12 Light-managed Ethernet Switch. This product comes with 5 fast Ethernet ports. One of them is connected to industrial computer that operates as the media for network data transmission, controlling the digital entertainment system, Led display, VoIP phone, etc. TES-250-M12operates flexibly in wide temperature; -40~70°C, ensuring stable data transmission when the transportation system is moving at a high speed. In addition, ORing’s circular back-up system, ORing, has greatly enhanced data transmission stability by assuring no networking failure.
Another achievement could be found in MRT’s Wenhu Line. Started in 1996, the MRT connecting Wenshan and Neihu Districts (abbreviated as Wenhu Line) is the first MRT Line in Taipei. However, it was not until 2013 that the whole line was embedded with railway surveillance system. Aiming at this specific project, ORing Industrial Networking Corporation has embedded a managed PoE Ethernet switch—TPS-3082GT-M12-BP1—that are specifically designed for railway applications. TPS-3082GT-M12-BP1 has 8 of IEEE 802.3af PoE fast Ethernet ports with M12 interface connectors, each supporting 48VDC power supply that runs at 15.4 watt. Also, two of them (1 set) support Bypass Gigabit ports. PSE device offers power supply for devices (PDs) that work compatibly with IEEE 802.3af, including surveillance devices, wireless AP as well as IP phones, etc. Besides, TPS-3082GT-M12-BP1
has the best Ethernet redundant technology—O-Ring, minimizing the recovery time to less than 10ms while supporting double power supply. When facing a power shutdown, TPS-3082GT-M12-BP1 has two ports for bypass to avoid network failure that may occur to Ethernet switches. Each cabin of Wenhu Line is embedded with a TPS-3082GT-M12-BP1, connecting to 4 cameras and entertainment systems. With such surveillance, this product has greatly enhanced the traveling safety for both passengers and the cabin crew. Aside from the benefits in terms of functions, the employment of TPS-3082GT-M12 has saved a lot of spaces since products are embedded under the seats.
TPS-3082GT-M12 and TES-250-M12 support reliable network system, and have both equipped with EN50155 certification. The M12 connector within is anti-quake and totally caters to the railway needs. Products of T Series that are mentioned in above projects have shown ORing’s high quality and customized service. ORing is a company that considerately meets clients’ needs and always offers the most suitable products for each case. In cases of Wenhu Line and Smiling Train, ORing’s products have once again stepped further in network data transmission, and such success is regarded as a milestone for another project triumph!
