Jim models HO scale and asks readers:

“I Love the old ‘Blue Box’ Athearn engines. They are easy to work on. I have two questions relative to the wiring of those engines.

First off – If I hardwire the engine, where do I solder the ‘Negative’ wire to on the frame, or drill a hole for a screw.
Secondly – I would like to run an A – B – A consist correctly. what do I have to do to make the second ‘A’ unit run backward to the first unit?

I am HO and run on a DC layout

Thank You for any held or suggestions. And no, I am toooo old for DCC!!!”
