Kato get bonus points from me for this:
"Please note, as these cars are repaints of Metra cars, some details may not be 100% accurate to the Caltrain cars."
It reflects a trend that I've noticed of manufacturers being more upfront about stand-in models (e.g. Atlas with their Ontario Northland tank cars, and BLMA's "foobalicious" Tropicana reefers)
