Feedback on my latest trains

Hello.
I specifically made these for a train vs cars game.

In comparison to the one I made almost 2 years ago:

These trains look good! They look realistic and the coloring of them makes them look nice. Good job on them!

I like these trains a lot. May I ask what they are for?
