Another one in trying to sort out the Populated SoCal session while driving my own train...
Full management of AI or free agent trains should still be possible without relinquishing your current train. At the moment all you can do is delete the train. You cannot assign an AI driver or get a detailed consist, for example to check what the default Run 8 boxcars are representing (like the full train of them which passed me at Woodford) so I can think about adding them to my collection once the currency exchange improves a bit.
