Park's red buses get an upgrade

Transportation can be a challenge in Glacier. If you have ideas, offer ride shares, or used a commercial service that you were happy with, let everyone know. Also, ask questions about road information, or share road information you may have.

Quote below is from here: ... ic-braking
It works like this: While the train is coasting, the engineer, using an eight-notch controller similar to the throttle, energizes the traction-motor fields, causing the motors to act as generators. The resistance of the motor field acts as a brake on the locomotive, which in turn helps to slow the train. The electric current generated by the motors in the dynamic-braking mode is a waste product and is dissipated as heat in banks of resistors located in the locomotive carbody.

I wonder if this hybrid system will, by coincidence or design, produce a brake assist albeit small,from the generator charging the batteries on the downhill legs of the Red Bus routes.
Be cool if so, it'll save a little wear on the brakes.

(The energy generated on the red bus is used to charge the battery pack of the hybrid system, and NOT dissipated as heat in a resistor bank as in a locomotive's "dynamic braking system".)

Any locomotive design engineers out there? 8)
