Dynamic braking effort SD40-2 simulation

Does anyone know of where I can find tabulated or graphical data on dynamic braking effort vs speed for various settings of the dynamic brake control?

Bob- Welcome to Trains.com! [tup]

EMD’s Service Manual graphs it. If you don’t find it anywhere else I can mail you a xerox-- I may not have the SD40-2 manual, but I’ve got the SD45T-2.

Can you email me a graph?

No scanner.

So photocopy at a stationary or photoshop and mail.
