EKE is a pioneer in Ethernet based Train Communication Networks (TCN). Trainnet® Switches and Software were used on board the first train with 100% IP-based TCN.


functions

Depending on the Ethernet modules that you select, the following functions can be achieved:

Ethernet Train Backbone (ETB)
The Ethernet Train Backbone (ETB) is a modern train bus technology enabling a cost-effective setup with a large bandwidth (up to 100Mbit/s Vs 1 Mbit/s for WTB). It can replace or be used together with WTB and other train buses. Like the WTB, it allows for dynamic train configuration.

Ethernet Consist Network (ECN)
The Ethernet Consist Network (ECN) technology can be used to create vehicle buses and also as train-wide communication network in the case of fixed consist (no dynamic train configuration).

Ethernet Switch
Ethernet Switches are used to connect devices to the Train Communication Network enabling networked devices to communicate with each other. A managed switch manages layer 3 protocols, such as DHCP and IGMP. It also allows for finer configuration of the switch. When the switch is unmanaged, that functionality must be implemented by a connected device (managed switch or CPU).

Ethernet Router
The routing functionality allows the switch to be dynamically configured, thus redirecting messages to devices based on the latest information. A common application is dynamic train configuration: when changing the order of cars, the train communication network is automatically reconfigured. The position and orientation of each car is identified, enabling flawless communications throughout the train.

Power-over-Ethernet (PoE)
Power-over-Ethernet allows for the passing of electrical power in addition to data with Ethernet cabling. It means you can dramatically reduce setup costs and wiring as only one cable is required to each device. More and more devices support PoE including surveillance cameras, displays, GSM antennas, emergency phones etc.

Train Computer Applications
The Trainnet® Ethernet Train Computer (ETC) has the ability to execute complex train applications. It can be used as an Ethernet Switch to directly connect devices or to create a consist network, but in addition, it can also manage a complete train computer. In practice, the ETC manages the other modules in the rack, such as bus modules (e.g. WTB for gateway applications) and Input/output modules (e.g. Digital Input Module for VCU applications). Using the Trainnet® ETC means you can create a very cost-effective Gateway, Vehicle Control Unit (VCU) or TCMS.


modularity

The Trainnet® Systems are modular. You can build an Ethernet Switch with just the functionnalities you need, for cost-efficiency. As a general rule, a standalone Trainnet® Ethernet Switch includes a Trainnet® Rack, a Trainnet® power supply and at least one Trainnet® Ethernet Module.

Trainnet® Ethernet Switches can be easily integrated into a more comprehensive Trainnet® system. For instance, the Ethernet Switch can be used as part of a Gateway, a VCU or a full TCMS train computer. That way, you are able to save space and money with a very compact and efficicent system.


racks

The Trainnet® Racks are available in different sizes: the most common are 20TE, 44TE and 84TE wide racks. The racks are usually 3U high but a 6U 84TE Rack is also available for larger systems as well as for the Trainnet® 1U ESU Switch with Power-over-Ethernet. Other rack sizes are also available: please ask us.


power supply

Most Trainnet® Systems can be powered using the Trainnet® PSV and Trainnet® PIU modules. When Power-over-Ethernet is needed, the Trainnet® PSE, Trainnet® ESS and optionally the Trainnet® PBU are used.
