Hello, I'm really trying to understand how one 'blocks' track sections. I'm using the Bachmann N EZ track and have been looking for Bachmann terminal joiners and connectors. I see Atlas products that seem to do the same thing but thought Bachmann would make something for their own track. Maybe not ? If you can use Atlas, do you use the "55" or "80" items for terminal joiners, regular joiners and insulated joiners ?. I first thought that the Bachmann 'under-the-track' straight pieces and the curved rerailer terminals track would be for track blocking but I'm confused now. Much thanks.
