I have been looking for generic specs for TT pit depths and am at a loss for accurate numbers. I estimate that 5' (to) 8' is close. Lots of variations in on line photos.
Any measured input wouild be appreciated. tt

I'll second your estimate of 5'-8'
I would also think in the 6-8ft range. Now the depth was determined by the size of girder used which would be determined by the engines that needed to be turned...weight, length ect.
I'm certainly no expert on turntable pits, but I think 5' 8" may be a little deep if you are talking about the depth from the top of the pit wall down to the rail. If you are talking about the TOTAL depth of the pit, then I think 5' 8" is a little shallow.
Check this photo from the Age of Steam Roundhouse turntable construction. The worker is kneeling where the circular rail will be installed and his hands are at the top of the pit wall. The bottom of the pit is at the level of the dirt in the lower left of the photo. That's got to be a good 8 to 10 feet for a total depth of the pit.
This photo and many others can be seen here.

Steamtown, Scranton, PA. at least 5 ft. This bottom tapers down quite a bit.
NS, Conway yard, Conway, PA at least 5 ft.
Frostburg, MD. Western Maryland Scenic. Maybe 4 ft. or less.

TT pit depths on model TTs frequently seemed overly deep. Especially when produced in a 96' size.
The pit depth is set by the reguired bridge strength/style and there is only so much weight any 96' engine can weigh.
The tie lined pit and pit rail foundation has great character. Thank you Matt.

Turntables, all they do is go round and round! What can go wrong with them? Well, the motor will fail at the least opportune time. The d--- pit can fill with snow and the table can lift out of the center casting. The operator didn't realize that the table was lifting as he was turning it to keep the snow down.

I can't say. I've never heard one discuss Zen or Existentialism.
The Turntable at the MM&A in millinocut,MA. is about 4' deep. My car is in the middle. We got a spin before we headed back to the coaling tower. 
This one has a snow plow on it to protect the motor.
