Description
The ALSTOM / Bombardier MITRAC DCU2 3EST000216-9644 is a Drive Control Unit associated with the MITRAC Train Control and Management System (TCMS) and railway propulsion equipment. MITRAC documentation identifies the DCU2 as a drive-control unit integrated into traction and auxiliary converters, where it controls and supervises converter functions, including traction-motor adhesion control and power management.
The unit is intended for railway traction and auxiliary-converter applications and is suitable for maintenance, repair, refurbishment, and replacement of compatible MITRAC equipment. The complete part number 3EST000216-9644 is important when sourcing a replacement because MITRAC equipment is configuration-specific and related modules are not necessarily interchangeable.

🔹 Railway System Integration
The DCU2 forms part of the MITRAC propulsion and control architecture. Bombardier’s MITRAC documentation describes the TCMS as using the Train Communication Network (TCN), including MVB for vehicle-level communication and WTB for train-wide information exchange. The DCU2 is integrated into traction and auxiliary converters rather than functioning as a conventional standalone PLC.
In the converter system, the DCU2 is responsible for control and supervision functions associated with the power electronics. This includes high-performance adhesion control for traction motors and power-management functions such as energy recuperation.
For replacement work, compare the original 3EST000216-9644 identification, hardware revision, connectors, converter configuration, software/firmware, and vehicle-specific parameters. Do not substitute another MITRAC controller solely because it belongs to the same product family.
🔹 Typical Applications
• Railway traction systems
• Electric multiple units
• Metro and light-rail vehicles
• Traction converters
• Auxiliary converters
• Train control and monitoring systems
• Railway maintenance and refurbishment
• Legacy Bombardier / Alstom propulsion equipment
🔹 Replacement Considerations
Before installation, verify:
• Complete part number: 3EST000216-9644
• Hardware and revision markings
• Traction or auxiliary converter type
• Vehicle-specific configuration
• Communication and connector arrangement
• Firmware/software compatibility
• Existing control parameters
• Converter commissioning requirements
The current listing identifies the item as New – Open box, but the physical condition and included accessories should always be confirmed against the actual unit.
