Nice! I was tempted on a few occasions to pick up that car set when it was available but never pulled the trigger. I see minitrix announced similar cars this year so likely won't be available till 2024.
Very cool. I've got a layout planned (8'x4') that uses a similar styled switching yard. The part of the figure 8 that is hidden in the upper right runs underneath then connects to an underground staging yard. The visible track portions are all fleischmann but the track underneath will be atlas flex and a few of their #6 turnouts. I have all the pieces to make it work just need to get a few other projects out of the way first.
