In 2009 or so I re-entered the hobby and built a shelf HO scale switching layout.   A few years later I added a new On30 switching layout that trains can continue onto the HO scale layout for additional run time.   I connected via three Atlas girder bridges to span a window in my layout room.   I became hooked on On30 and Bachmann products.   When we relocated to Maine in 2016 I constructed another On30 layout section to the preexisting On30 and HO layouts once again requiring  four Atlas girder bridges this time to span a window in my new layout room (spare bedroom).   I continue to add Bachmann locos, most recently a Heisler, and typically buy their flat car frame units and cut them down to shorter lengths to represent a back woods flat car for hauling timber, cut pulp wood, crushed rock, etc. and also construct box cars with these frames.   I now operate a Forney sourced used from the UK, a Shay, a Gas Mechanical and this new Heisler.   I did purchase a Bachmann Spectrum On30 2-6-6-2 Articulated Loco w/Tender but soon found out that it was too large for my track curves so I sold it to someone in the UK.   I too hope they bring out the Shay again - I had to send mine into Bachmann for repair and they did a great low cost repair on this loco.   Happy railroading!

Detailed instructions please.   I will never convert to DCC so I will stay with DC operation.

Do you need to access a hidden screw under those wires or does it just "snap" out?   Thanks much.
