When first loading in you are asked to move to a point and start loading coal. You are given the AC4400CW locomotive which has low speed control making it ideal to load the wagons. There are 2 issues that arrise. Issue 1: The banking locomotive (which you are not told to enable with the "Banking COMMS" button) is configured incorrectly with regards to it's MU-A valve. Its set to "trail 6 or 26" which applies the breaks. You have to set it to "Lead or Dead" and bail off the breaks either by walking all the way to the back, or use an external camera and mouse over the controlls. Issue 2: If you have enabled the "Banking Comms" button and started the slow speed loading using the slow speed control on the AC4400CW , after a certain point during the loading where you start going downhill, the banking locomotive (which doesnt have slow speed control) works against the leading locomotive pushing your speed way higher than what you set in the leading locomotive. At this point you can see the leading loco going into dynamic breaking but its not enough to maintain the set speed. You end up not loading the last 7-8 wagons unless you actively use the breaks. The solution i found is to use external camera when you start, switch the MU-A valve to "lead or dead" and bail off the brakes on the banking loco. Afterwards you have to NOT enable the "Banking COMMS" on the leading locomotive, allowing you to slowly load the coal as you are supposed to do. When loading the coal is completed, you can enable the banking loco to help you get up the hill. Possible fix would be to replace the banking loco with an AC4400CW instead of what it's currenty, but havent tested if the slow speed control applies to a banking locomotive. I've created a ticket mentioning the above. It feels as if the banking locomotive is unessesary. Any thoughts?
