1121 non derail

...do they still require the controller box to be hooked up to the terminal posts?

No. The controllers are just wired in parallel.

Can I just put the middle post to a grounding bar or do I even need to since the track completes the common circuit?

 You don't need to, but you can, it may make for a neater installation if you use those center posts as connections to the track instead of lockon clip 2.

I'm necro'ing this thread to ask another question. Attached is a diagram of the 1121C control box. It appears to me that the controller is just a large DPST switch. (Ha. Switch for a switch.)

To make a cleaner install, could I just use a small momentary DPST toggle with modern non-crumbly not 80 years old wire? 

Yes you can. You can also purchase FC-3 or 3-CW wire by the foot from most any parts supplier to refurbish your control boxes.

Perfect! Thanks. I'd rather just leave the control boxes as is, the last one I took apart ended up with crumbled bakelite from the screws being in there for 80 years.
