Brand new. I apologize in advance if my questions are really stupid. I'm going to start off with something small and simple. I'm looking at this set-up. Please advise if you can, what does it mean by "blocks". I'll have an EZ Command system, exactly what is it that I have to do at those areas marked "G" at the wyes? Will the Golden Spike ready-to-run N-scale train with DCC command have all the accessories (power) needed to operate this track once the track-pack and extra tracks are added? If not what else will I need? What is the purpose of having 4 "11.25" radius terminal" at those spots specified? Any help is much appreciated.
This plan shows a track arrangement called a "wye", and it can cause a polarity conflict unless rails are insulated at certain points. The track plan you showed does not have any wye arrangements, and does not need insulated joiners if you are running nit with some kind of DCC system. By the way, the word "wye" has two meanings. In a track plan, the arrangement of tracks shown in my diagram is a wye arrangement. However, a wye SWITCH or wye TURNOUT can also refer to a track switch where the track splits into two curves going inj opposite directions, instead of one straight and one curved. A wye turnout does NOT need to be used on a wye trackplan arrangement although it sometimes helps.
