Easily done with some of my throttles. Depends upon how fancy I want to go.
Had one that would take about twice the real time to stop a train at one end
of the variable control and would stop the train in about 5' in the other
end. I have given away a fair number of throttles over the years. Still do
have the little one in the 1"x1"x2" box tho and that one is good for only 3
amps due to it's size. That one has a fixed speed change rate as it is so
small.

And to change one of those values take what... replacing capacitors?

BTW, do you have seperate control of the acceleration and deceleration of
the speed of the loco in DCC?

Yes.

Does the acceleration curve act like a real
train where the acceleration can be fast at slow speeds while it is a lot
slower at higher speeds?

It can be, depending on how your speed curve is set up. I prefer to
simply set up my locomotive so that the percentage indication on the
throttle approximates speed in MPH... but momentum can be used with
these settings, too.

Can you set the deceleration rate without hitting
a bunch of buttons?

Red herring. Can YOU change it without hitting a bunch of buttons, or
completely rebuilding your throttle? I don't mean a theoretical
vaporware throttle, I mean the ones you actually have right now.

With DCC, I simply enter OPS programming mode (one button push), enter
the CV I want to change (button push or knob turn) and the value to
enter (button push or knob turn), then hit "enter". Done. Takes less
time than it did to write this. Acceleration and deceleration can be set
independently... and you still have "emergency stop" available.

I built one throttle that had basically 8 speeds (just like a typical real
loco) and responded to the load by slowing down until you upped the
throttle.

If you WANT to do that with DCC, you can. Just set your speed table to
have eight intervals (by setting several speed table CVs to the same
value) and enable momentum. However, since physics doesn't scale, why
cripple your locomotive that way. I notice you said you only built ONE
throttle that way... obviously, it didn't really give you prototypical
operation after all. Something things are better in theory than in
actuality.

Seperate brake control with a variable pot to set the braking
rate.

The Digitrax Zephyr unit has a separate braking lever...not something I
find particularly useful or conducive to prototypical operations. Again,
you only put that on one throttle, right? Why would anyone want to
repeat your mistakes?
