You're welcome, Kevin. MTH made a number of nice versions of the 6000 series in the original cream/mercury green colors, the white and dark green, and the silver bicentennial versions. Even thought I model in S scale, I bought the cream/mercury version and added figures and LEDs so that it would light up on display. Those are the cars that I first rode when going to high school and "operated" by pressing a hidden button above the doors when in the terminal so that I could bring in cash bags to the cashier at the end of the day. I fully understand your love of transit trains. It brings back a flood of wonderful memories. (The Union Illinois Train Museum has an entire CTA station I worked as well as a number of of buses I drove. It's a bit disconcerting to realize my past now lies in a museum!)
