Now we're talking. Melgar, I love the Bipolar. Great looking engine. Marty, your layout is legendary. Would love to see it someday. Nice catenary systems, Jonathan and Dan. Great pictures Pat and Billy and I loved the video, Glen. Today, I'll add a unique electric because it's an electric switcher. The BB1 originally run as a pair but later separated as a B1 is a small electric switcher used by the Pennsy to switch cars in the Northeast Corridor.
