There is a feature with the circuitry on American built locomotives called " Extended Range Dynamic Braking ".

I have not seen this in any modern locomotives for Open Rails.

Steve, thank for answer, also, thank to Mike.
Well, during WWII, there was number of steam female-engineers; after it became strictly male profession. With very rare exceptions.
Last years, with microprocessor controls, the doors might be open for girls, but I didn't hear anything yet.
I think, in "progressive" states, the emancipation was a motive. And it's not bad in this case.

Also during WW II women were ferry pilots for bombers to get them to England from the Boeing and Consolidated factories. B-17s and B-24s. I don't know who ferried the B-29s to the Pacific Theater.

No Mike, Yardmasters are not in engine service by the union agreements. However, that was the way it was in 2012 when I retired.

Hey Steve, I realize that. My point was train marshalling. Yard masters were as far as you could go on the tail end without becoming management.

Good day, all If anybody is interested,

VIA F40PH-2D
Blended Pneumatic and Dynamic Brakes

The Throttle Handle has nine detent positions: IDLE, plus 8 power positions. When the Reverser Handle is CENTERED, and removed from the Controller, mechanical interlocking prevents the Throttle Handle from being moved out of IDLE into the power positions.

Unless the Throttle is in the IDLE position, Dynamic
Brakes will not be automatically blended with the Air
Brake System.

Here's examples of the 10 sec. pauses:

PASSENGER TRAIN OPERATION GUIDE Section 3
BLENDED BRAKING PROCEDURES

BRAKING FOR SLOWDOWNS
1. To obtain Blended Braking, gradually reduce the Throttle to
IDLE.
2. After a minimum 10 second pause, make a slight brake pipe
reduction. Do not Bail-off the Independent Brake Valve during
this, or any subsequent brake pipe reduction.
3. Make additional brake pipe reductions as needed, normally in
increments of 21 - 35 kPa (3 - 5 psi), until the necessary
retarding force is obtained.

HIGH SPEED STOPPING
The "one application and graduated release" method should be
used when braking is initiated at speeds of 32 km/h (20 MPH), and
above. To allow a gradual release of the brakes, braking should be
started sufficiently in advance of the selected stopping point.
1. To obtain Blended Braking, gradually reduce the Throttle to
IDLE.
2. After a 10 second pause, make a minimum brake pipe
reduction. Do not Bail-off the Independent Brake Valve during
this, or any subsequent reduction. Etc.

I've been trying to find out what changes were done to the Rebuilt VIA F40PH-2D,
