The way the dynamic brakes are set up for the ES44AC in the simugraph is unworkable. You can apply notch 1 on them and one time get a klb of 14, next time it might be 23. Also, when you reduce them, they do not come off like they should but remain high. They should go on in steps just like the throttle applies power in steps. Another thing, in these newer locomotives, you cannot have both the independent, loco brake, and the dynamics on at the same time. If the engineer does not bail the independent, the dynamics will come off. Finally, when you go into setup on the dynamics, there is a delay before they will begin to work. This allows the control circuits to adjust. Thanks
General shape of speed/force curve looks OK, but there is very limited control for it. On first notch 1.0-13% you get: 29kLb@5mph 30kLb@10mph 30kLb@15mph 25kLb@20mph 21kLb@25mph 18kLb@30mph 16kLb@35mph 14kLb@40mph 13kLb@45mph 12kLb@50mph 11kLb@55mph 10kLb@60mph This minimal set is 25% of total capability. Normaly you should be able to set any force up to maximum which is limited in speed range like on SD70.
I have seen an issue with the dynamic braking in HSC also. On Will Wet Coal Burn, applied 22% and got 30kLb. Applied 24% and got 66kLb. There is no middle ground. Scaling is all wrong.
Yeah, I hope they can apply the same kind of dynamic brake mechanics they have on the SD70 to other routes. The SD70 is really nice the way you can fine tune the brake force and maintain a steady speed. With the ES44AC you're kinda ham-fisting it, feathering between too much and too little force. DW
