I get to see many locomotives in my capacity as a Lionel Tech. Today I had a Milwaukee Road FlyerChief Plus for a minor fix. This is a Bluetooth engine. I have the free APP on my phone and started playing with the engine. This thing is fantastic. It works perfect every time. I love the fact when you change direction the app drops the speed slider to zero. Everything about this app is very cool.
BTW, the Northern is a big time winner. I am so happy for the Flyer Guys getting cool toys.
