The cab of a WAG6-C. While the A9 & SA9 look like those on other CLW built locos, power seems to be controlled via a single lever like that found in a WAP5/7. Does the WAG6C have notch based power control or some other system. What do the experts make of it? Also, what purpose would the wheel to the right of the pic serve? Emergency brake?
