Are 151's etc the best way to block control a layout?

[lckiii]

 

In buildign my first new layour in ten years I want to have block control (but no command control) for my post-war layout.   Obviously I willneed to control power to the blocks.  Are the old Lionel accessories my best bet, or are there less expensive options?

 

Thanks

I don't understand what you mean by "block control".  The 151 is simply a two-aspect semaphore, which won't help with anything that could be described with that term.  What do you expect "block control" to do for you on your layout?
