SAINT PETERSBURG (RF) – the successful delivery of the first 6-car metro train of the new-generation "NeVa," which will serve residents of St. Petersburg. By completing this project Lokel has finished the development, implementation, and testing of another type of superordinate control system (TCMS) developed specifically for this type of cars.

This demanding customer required highly technologically advanced and reliable products, giving Lokel the opportunity to deploy almost all of its own products and technologies in one project. In addition to the vehicle control unit, the metro in St. Petersburg is also equipped with HMI (Human Machine Interface) touchscreens, UIC WTB GATEWAY, remote diagnostics system IRDS (Intelligence Remote Diagnostic System), and Input/Output Units (IOU) used to process the input and output signals of the controlled train.

The backbone of the entire implementation of the superordinate control is the WTB bus (Wire Train Bus), which together with the MVB bus (Multifunction Vehicle Bus) represents the Train Communication Network (TCN). This type of communication between the individual devices of railway vehicles is possible thanks to highly sophisticated devices called UIC GATEWAY. The MVB vehicle network is further complemented by CAN and ETHERNET networks.

The concept of the control system of the St. Petersburg metro has been designed to allow the control of up to 8-car units. The end customer required that the superordinate control system works in a HOT redundancy mode. This ensures that if the control system fails, the duplicate unit will automatically take over without the driver having to intervene in the control of the vehicle.

We are very pleased that the implementation of our work and technology in the St. Petersburg metro once again confirmed the great quality and reliability of our systems.
