KonHMI – How it started

Incomplete solutions, bad obsolescence management, expensive and time-consuming repairs, decreased availability of rail vehicles, and poor customer service. We believe that these are not desirable features in your rolling stock.

Over the last decades, we have delivered TCMS – Train Control and Management System, for more than 400 rail vehicles, carefully listened to our customers, actively wrote all their problems with equipment, and learned about their frustration and needs. During this process, our equipment has been improved to the level that in 80 million km, rail vehicles stopped only twice because of the failure of our control system.

HMIs, as component-of-the-shelf, is left as one of the weakest components of TCMS. After the warranty period passed, repairs became very expensive, parts were unavailable, spare parts stock drained, and customer support becomes very bad. So, we decided to deal with it and learn from others’ mistakes.

The result is our proprietary KonHMI with the following characteristics:
