Those are Bombardier built BiLevel cars which use regular steel, therefore all of them are painted to prevent rust. The second car in the photo was originally used by Metrolink in Southern California, and is still painted in Metrolink livery - with Metrolink's text and logo removed. Eventually those cars will get repainted, by whomever buys them, when Caltrain's new Stadler built BiLevel EMUs enter service, or if they last a little longer, when Caltrain retires them. Which might explain why Caltrain hasn't repainted that one in the wrong livery yet.
