Western Railroad Discussion > BNSF ES44AC QuestionDate: 11/12/12 22:43 BNSF ES44AC Question Author: ajgreen Hi all.
When in dynamic braking, what is the power setting of the unit. Some locomotives revert to idle, whilst others run in Notch 4 or 8 when dynamic braking is in use. Can anyone shed any light on the this and in particular the BNSF ES44AC's? Many thanks, Allister New Zealand.

the unit will increase throttle setting ie Run 4. |
