Logging Locos, Logging Track Plan, Logging Mill, Mainline Pick-up

[railandsail]

Yesterday I got out a few of my logging locomotives to do a little measuring, and to see if they could operate on minimum radius tracks.
I wanted to see what sort of minimum length turntable bridge might accommodate the locos I had. I chose a couple of my longer ones,...
1) 2-6-6-2 brass Toby

 

 
2) 2-6-6-2 Mantua

 
3) Rivarossi Heisler w/tender

 
 
It appears as though the Heisler will require the longest turntable bridge,...8” should do it.

I'm hoping to put in at least one 'gallows style' turntable at the tip of my logging peninsula
 
The smallest radius fixed track I had was 18”r. It appeared that all 3 of these locos could negotiate that radius.
