The Trainnet® Human Machine Interfaces (HMI) are interactive displays. They can be used to display information to train drivers or crew members with interactive displays. They can also be used as CCTV monitor as well as for any Trainnet® applications.

key features

The Trainnet® HMI are flexible devices providing ease of use and robustness for all Trainnet® applications.

The touch control buttons positioned around the display area provide great durability with no mechanical part to wear out. The layout of the keys is designed according to the international UIC 557 standard. You can easily configure the keys to match any of your requirements.

The flat displays, including the touch control buttons, are protected behind an anti-reflective vandal proof safety glass (IK 07 , IP 65 tightness) for durability.

As the displays are very compact, they can be fitted virtually anywhere in the train and are easy to mount (rear fixing for protection). Two sizes are available for flexibility: 6.5” and 12.1” with respectively 640 x 480 and 1024 x 768 pixel resolutions.

As part of a Trainnet® System, the HMI is usually configured and controlled by the Coach Computer’s CPG (Central Processing unit with Graphics controller). There is a DVI-I interface and a touch screen interface integrated into the same cable.

The Trainnet® HMI also sends self-diagnostics data to the Coach Computer, such as module temperature and the count of lamp’s operating hours. The display does not include any moving parts and the lamp is the only replaceable component. The absence of components that are subject to any wear out guarantees a long unit lifetime.


The Trainnet® HMI 12.1” is available as a full touch (FT) screen as an option. The 12.1" FT display does not have touch control buttons around the display area.
