Three issues: For the GEVO the slow speed control is not working. I have the same issue with the AC4400 so probably the code is copied wrong. Second, the coal load in Rose Bud mine loads brown stuff and results into grey coal. Both a bit unlikely. Can this be fixed please? I tested this using the journey coal loading service. The thisd issue is that if you start the service to load the second part of the train, the wagons of the first part look empty. This may be a technical limitation, but in that case it is better to make the loading a single service instead of a two part service. Screenshot from the second part of the coal loading timetable run
