The title explains itself. I have made multiple attempts to make the AI trains run faster than 43 mph but will only cap out at 43 mph. I have deleted every single signal, spent 5 hours updating every piece of track to "Perfect", I have also added speed posts every so often, and will not at all change the speed limit. I have even set the drivers max speed to 70 and refuses to even go past 43 for any locomotive or consist. Is there a setting I am unaware of? I have looked everywhere online and cannot find a single item making me believe I am the unfortunate one in the world to have this issue. I am losing my mind trying to figure this out.
