1. What is the primary control methods?Wired (often integrated with ECP brakes) and wireless (RF connectivity) communication systems
2. What is the technological precursor/companion?Electronically Controlled Pneumatic (ECP) brake systems, which facilitate wired DP integration
3. What is distributed power in trains?Distributed power means having extra engines hidden along the train that the main engine can control from the front. This helps the train pull more weight and move faster.
4. Why do trains use distributed power instead of just one engine?With many engines spread out, the train can pull more cars, go up steep hills easier, and stop more smoothly, which keeps the train safe and saves fuel.

Tractive Effort: The force exerted by a locomotive to pull a train, crucial for overcoming resistance and accelerating.
Slack Action: The dynamic movement within a train where cars bunch together or stretch apart due to changes in motive force.
Heavy-Haul Railways: Rail operations characterized by extremely long and heavy trains, typically transporting bulk commodities.
