Lantech Ethernet Switches for use with IEC 61375 Data Networks

A Train Communication Network (TCN) is an Ethernet-based network control system that applies to rolling stock control, detection, and diagnosis. The international standard, IEC 61375, is defined with cooperation between members of the International Electrotechnical Commission (IEC) and the International Union of Railways (UIC).

The white paper details that:

  • Specifications of Network Topology in IEC 61375-3-4
  • Specifications of ECN Networking Data in IEC 61375-3-4
  • Cross train-car communications – Integration with R-NAT in IEC 61375-2-5
  • Recommended Lantech IEC 61375 Ethernet Switch Models

The IEC 61375 standard’s definition regarding the TCN can be divided into two parts: one is an Ethernet Train Backbone (ETB), and the other is an Ethernet Consist Network (ECN). The ETB is in charge of connections between the ECNs in each car. The requirements and applications of ETB are defined in IEC 61375-2-5, while the requirements and applications of ECN are defined in the IEC 61375-3-4 standard.

Milestones | The markers of success which HS2 is targeting over the coming years

Our August/September 2021 edition of RTM covers many of the changing aspects of the rail industry, including key changes involving infrastructure and stations. Read our breakdown of the key milestones with HS2 between now and 2024, while elsewhere we investigate the role which hydrogen fuels could have on UK rolling stock. We also delve into the ever-growing digital world of the rail industry, while from Page 65 onwards, we include our Railtex / Infrarail 2021 supplement – your chance to gain a wealth of valuable information about the exhibition, right at your fingertips.
