The DPWCS (Distributed Power Wireless Control System) enhances rail operations by distributing locomotives along the length of a train. Here’s how it works:
- Concept: DPWCS couples locos through RF communication, allowing them to be anywhere within the train.
- Advantages:
- Efficient communication within a 3 km radius.
- Train brake application and release feedback.
- Isolation of defective locos.
- Lower draft/buff forces.
- Components:
- Control & Communication Unit (CCU): Monitors system activities.
- Driver Interface Unit (DIU): Displays information.
- Brake Interface Unit (BIU): Ensures synchronized braking.
- History: First fitted in WAG7 electric locomotives, DPWCS revolutionized long-haul train operations.
The DPWCS—a wireless link connecting locomotives—drives safety and efficiency on Indian Railways.
