Microprocessor Interlocking System MPC-U

MPC-U is the core system. It implements all the functions of train traffic monitoring and control, route and individual control of trackside equipment.

The MPC-U platform implements automatic block signalling MAB-U, semi-automatic block signalling MPAB-U, track circuits MRC-U, axle counting system MSSO-U, and other functions for controlling train traffic and trackside equipment of railway automatics. These functions can be applied as stand-alone systems or integrated into the MPC-U.

The safety and reliability of systems based on the MPC-U platform are confirmed by the international certificate of compliance with the highest safety integrity level SIL4 and a decade of operation on mainline railway lines in Ukraine and Europe.

Since its first implementation in 2012, dozens of projects have been developed and implemented based on the MPC-U platform.

Implementation of MPС-U on railway transportation will allow to:

Improve estimated train capacity and safety

through the use of digital fail-safe control and management technologies

Remotely operate

any type of trackside equipment, shunting areas and yards

Minimize the probability of interlocking system failure

through a triplex secure processor structure (2oo3d), redundant object controllers (2oo2d) and diversionary software

Simply integrate

with various interlocking, centralized dispatching, traffic control and other systems via digital serial and parallel discrete interfaces without using relays

Significantly reduce labour and financial expenses

of SCB equipment maintenance, switch to condition-based maintenance due to deep self-diagnostics of MPС-U and diagnostics of SCB equipment

Key features

Possibility to build interlocking systems

in accordance with the “1520 area” standards and European standards for traffic safety and quality assurance

ERTMS/ETCS compatibility

Unified complex of technical means and unified interfaces

for all railway automatics systems: digital track circuits, ALSN, automatic block signalling, and semi-automatic block signalling on the basis of axle counting are integrated into MPC-U without additional linkages

Cyber security,

in accordance with ISO/IEC 27000, EN 50159, IEC 62443 standards

Distributed structure

allows to place the equipment both in a centralized way (in one room) and as distributed fragments at stations and open tracks (with the equipment placed in standard transportable modules)

The passive cooling system

increases system reliability and minimizes the frequency of periodic maintenance

Guaranteed power supply.

Redundant power supply system and echeloned overvoltage protection

Low “lifecycle” cost

Operational support and service

provided by the manufacturer for the entire system lifecycle

Based on MPC-U platform a range of microprocessor railway automatics systems is implemented

Automatic block signalling MAB-U
Semi-automatic block signalling MPAB-U
Track circuits MRC-U
Axle counting system MSSO-U, etc.

These systems have the same features, reliability and functional safety (SIL4 level) as MPC-U

They can be used both as stand-alone systems and functions integrated into MPC-U
