Who doesn't like the iconic 7760 ? Here in a fully autonome PF version with a standard PF train motor modded to have a pair of center-wheels to give a more 7760:ish look.
I use a PP3 battery which is hidden behind panels 1x4x3, and that way it has been possible to respect the original overall dimensions.
Hope you acknowledge the 7760-feel
