All recorded today (3/26/24) at my school today, I saw in the Horseshoe curve chat that 42 has two private cars and well, I saw them. And yes I asked for permission to go outside to see it, and I saw 43 and 645 as well which was good enough for 3 trains in total.
(Note: Don’t try this at your school unless you get permission from the school staff) and enjoy the short video of 3 trains.
