I kind of wondered about this. I would have sworn that when I was in
the shop staff at Kamloops that the SD40s did not have extended range
DB. Seems to me in DB, they would only motor up as far as throttle 4
and that was it.

I have been running SD40's for CP since the late 70's and I have never
found one of them with extended range dynamic brake. Our peak dynamic
brake is about 19 mph and below 13 mph, it drops off drastically and
has
to be augmented by using the independent brake.
This is quite different to the AC power we now use where the db
efficiency continues right down to basically 0 mph. You can stop a
train
using db now.

If I'm not mistaken, all of CP's orginal 40-2's have extend range
brakes
and the largest fuel tanks...
Extended range dynamics was standard on the dash two line for that
option...(I think)
