uncut bus wires with no joints other than with the power poles at each end of the module
Of the two, the later has greater importance in reducing voltage drop across modules. Therefore, the
common practice of a barrier strip at each end of a module with pigtails to attach to the adjacent
modules should be discoraged.
UP3/5 Plug-in Panels
UP3 panels have been replaced by UP5 panels. Both work just fine in our layout loconets.
It is advantageous to have plug-in spots for throttles located around the outside of the layout. While
portable plug-in points can be attached to modules during show setup, building them into the front panel
(and occasional rear panels) of modules can simplify setup. Including a UP3 or UP5 panel on a module is
strictly at the option of the module builder.
If you choose to include UP3/5 panels on your module be sure that any folding legs do not damage the panel
when the legs are folded.
