I do not know if this was requested before... But yesterday I tried to make a Scenario Planner on SPG, using a double stack train, but surprisingly it is not available. Only autoracks and coal trains are available to use with AC4400CW. I believe it will be really nice to have double stacks and grain train available to run with this tool. In the case of grain, please notice there is only one timetable for it. Furthermore as I have made new liveries for double stacks, -and soon on grain car too - I would like to see them on my train. Hope this could be possible!.
