I can run any of my locomotives, including the few conventional models I have, from my remote controls. All the switches and turntable controls are also available on the remote as well. Finally, I have a wireless power control that allows me to individually control each of the four transformers that power the layout or kill power to the entire layout. Did I mention I can run two or three trains on my mainline at the same time with individual speed control?
I have no quibble with folks that like to be tethered to the transformer handles, I'm just not one of those guys. As far as "hands off" vs "hands on", I simply don't understand that reference. Whether I'm holding on to a transformer handle or the knob on my remote, I'm thinking I'm in the "hands on" camp. I would define "hands off" as the guys that have computer control and just watch the trains run without any human interaction.
As for following the train on the layout, it's easy with the remote, and I have total control of it at any point in my little walk alongside the train.
