### Flexx family

###### BRAKE CONTROL

##### Flexx Family

##### Advanced Integrated Brake Control

##### The FLEXX Family represents the latest generation of integrated brake control systems for both mainline and in-service applications.

##### With Regioflexx and Regioflexx, the braking is natively controlled per axle, embedding the powerful DistanceMaster wheel/rail adhesion management solution to ensure guaranteed & predictable braking distance — regardless of track conditions.

##### Designed to reduce Total Cost of Ownership, the FLEXX Family extends overhaul intervals and minimizes component replacement

##### SIL4- based architecture enables advanced functions, elevating train safety and performance to a new level.

**Customer benefits**

### MBC

###### BRAKE CONTROL

##### MBC

##### Modular Brake Control

##### Designed for mainline trains, WT’s MBC brake control unit offers flexible, architecture-ready braking tailored to your system’s needs.

##### With pre-configured modules for direct and indirect braking, Magnetic Track Brake control, and parking brake management, MBC eliminates costly development and validation efforts.

##### Delivered with Gemini II electronics, MBC is a true plug-and-play solution — enabling efficient integration, reliable performance, and reduced time-to-market for modern rail fleets.

**Customer benefits**

### MSM

###### BRAKE CONTROL

##### MSM

##### Modularity at your service

##### Brake systems rely on a wide array of auxiliary components to supply air, isolate functions, and monitor pneumatic operations — all of which must be seamlessly integrated into the vehicle.

##### At WT, we understand that modularity matters. That’s why we developed the Modular System Modules (MSM): a flexible, cost-effective solution built around 14 proven and reliable modules.

##### MSM offers the ideal balance between pipe-mounted equipment and traditional pneumatic panels, covering all market needs while simplifying integration.

**Customer benefits**

##### With full configurability, MSM adapts effortlessly to specific project requirements — delivering performance, efficiency, and ease of installation for rolling stock manufacturers.

### Gemini II

###### BRAKE CONTROL

##### Gemini II

##### A long service electronic history

##### Gemini II is the electronic core of WT’s brake control systems — trusted across all rail segments, from very high-speed trains, and designed for global deployment.

##### In service since the late 1990s, Gemini II is a modular, field-proven platform offering unmatched flexibility in configuration: sub-rack dimensions, interfaces, communication protocols, and power supply can all be tailored to project needs.

##### Built on WT’s proprietary operating system, Gemini II is immune to common vulnerabilities and exposures (CVE), ensuring robust cybersecurity and long-term reliability.

##### With its proven performance and adaptability, Gemini II is the smart choice for safe, scalable, and future-ready brake control integration.

**Customer benefits**

##### Gemini II platform boards are constantly updated with the life of electronic components, ensuring long-term asset management for your investments.

### DISTANCEMASTER

###### BRAKE CONTROL

##### DISTANCE MASTER

**Datasheet**

##### The adhesion management solution for optimum performances

##### Adhesion variability is a major challenge for rail operators — impacting braking performance, causing wheel damage, and leading to costly disruptions such as timetable changes, unplanned maintenance, and train downtime.

##### DISTANCEMASTERTM is WT’s advanced adhesion management suite, designed to help operators maintain stable and predictable braking performance, even under degraded conditions, while significantly reducing wheel flats.

Three key innovations power this performance boost:

- Adaptive Wheel Slide Protection (A-WSP): Optimizes slide control in real time.
- Deceleration Control (DM-Control+): Maximizes adhesion usage across the entire train.
- Smart Sanding Management (DM-SmartSanding): Intelligently deploys sand to locally enhance adhesion when needed.

**Customer benefits**

##### With DISTANCEMASTERTM, operators gain greater control, improved safety, and reduced lifecycle costs — making it a smart investment for modern rail networks.

### IBU

###### BRAKE CONTROL

##### IBU

##### Integrated Brake Unit (IBU)

**Customer benefits**

##### The IBU brake control unit delivers precise and reliable management of both service and emergency braking — at car or bogie level, especially when paired with WT’s Gemini II electronics.

##### Fully configurable and available with integrated Wheel Slide Protection (WSP) valves, the IBU is compatible with both single and double pipe architectures for xMU and high-speed train applications

##### Trusted across Europe’s regional fleets, with main car builders' platforms, IBU stands for proven reliability, operational flexibility, and ease of integration — making it a smart choice for modern rail systems focused on performance and safety.
