NPH&ARR - Need help with Conventional Blocking

Does this silence mean everyone now runs command?

Not only do I want help with where to make my blocks, but what is the best way to then power each block?  Should every block be selectable to a transformer, or should spurs just be toggle on/off to the transformer controlling the mainline switch they come off of?

Seems like you want some input,  just some random thoughts;

You photo came thru squished side to side on my screen.  Not sure what you are really looking for but I would encourage you to do more research on track plans and visit a bunch of layouts to ask questions.  My first impression is it seems kind heavy buzy like a corn field maze.  Going around in different directions just to go in different directions. 

A switching layout is one thing, this just seems a tad busy.

This plan costs some serious money in switches.  I am  little concerned you may see it as a little much after a while.  My thought is to hesitate before jumping in. 

As far as blocks.  EVERY RR needs blocks.  Maybe not as many as you show but still a RR needs an assortment of blocks for a variety of reasons,  Conentional engines and short searchs first come to  mind.

This sketch seems to need two power sources for a conventional approach.  Toggle or rotary switches an be used.  If only two power psources in conventional toggles are fine.  More than two toggles can still work but rotarys come in handy with three or more power sources.

Look into star wiring.  If you are not a fortune teller you can not rule out DCS years down the road.  Everything runs well with star wiring but DCS does not run well with conventional TMCC style wiring.

Seek out John Armstrong and MR books on layout construction.  Hold off and go slow. 

A lot of layout questions recently, so the "design" guys may be busy. Also, you may want to specify what type, and size (curve diameter) of track you're going to use. Be aware some locos like some styles/sizes better than others too. I really don't see any issues, and that could be another reason for lack of response. If your comfortable with that many blocks, switches, turnouts, wiring, relays, and the price. Why not?. It is busy, but I figure only you, know how you run your trains, and like what you've got going here.

It will be an interesting pike to operate.  In my experience I see three things you might want to consider. When you are coming into a switch facing the points I have found the best operation will occur if you can place at least one full section of straight track ahead of the switch.  In your drawing I see several places where you do not do this but there is room to adjust the track work to get the straight in.  Second is reverse or S curves curves should be avoided. Try to get one straight section in between reversing curves.  The third is do not under estimate the amount of time it takes to wire a layout. I would suggest putting in all the insulated pins you think you will ever need, but jumper them out under the layout to get something running as soon as possible.  You will need to get an engine running check out your track work and provide additional movation.
