Hello, new guy here. I've started with N gauge using the Bachmann EZ Track. I'm hoping it will all work out, it just seemed that the EZ track would be good for my space & construction. I'm trying to understand how one can 'block' track sections with this EZ track. I've seen the Atlas rail joiners, electrical & insulated, and the terminal joiners and how you can also use the Atlas selectors. But there are '55' and '80' types so I'm not so sure now. Seems that Bachmann should sell there own stuff. Bachmann has those under-the-track straight terminal track & the curved terminal rerailer pieces so I wonder if these are used for track blocking. Can they be used both for your electrical hookups to your powerpack 'and' to isolate your track sections (and your use of the insulated rail joiners ?). Am I going about this all wrong ? Help ! Much thanks.
