Here's my latest custom LEGO passenger train MOC, now in what I'm calling 99% complete state. It's an electric multiple unit, intended to be run in a realistic 2- or 3-car configuration, but compatible with the middle car from my older train as well. It's also infrared remote controlled using current Power Functions components. The video shows the overall design as well as plenty of running footage around both loops of my layout..
As always, things will surely be tweaked over time!
