The Arkansas & Louisiana Missouri Railroad had their shops in Monroe, Louisiana. Mike Palmieri made a visit there back in February of 1977 and recorded this view of the road’s tired, but serviceable turntable in front of the roundhouse.
The turntable appears to be an “Armstrong” type, in that it is rotated by personnel pushing on the bent-up pole seen in the foreground projecting out from the bridge. I’ve actually done this myself on the Reader Railroad’s turntable up in Arkansas (great fun for a railfan, perhaps not so much for an employee).
Note the pit is somewhat filled with water. I visited this facility myself many years later, perhaps the early 90s, and seem to recall that the pit was filled with water then. If it stays that way, I can’t help but wonder what shape the table bearings are in!

Edit: Ron Findley reminded me of some dates. He and I visited the road in May of 1989. Here is a photo of the roundhouse taken by Ron in May of 1989. The turntable was still in place at that time.

He and I again visited during an NRHS-SELA Chapter excursion on the now Arkansas, Louisiana & Mississippi Railroad in November of1992 (Georgia-Pacific had purchased the road by that time and renamed it). By that time the turntable pit had been filled in and the bridge lay on the ground nearby.
Jack,
You should have checked the chlorine levels. The crew may have used it to cool off on a hot day! LOL.

Jack or Matt,
Do either of you know where in Monroe the AL&M yard was ?
Tom, it’s been so long that I don’t remember exactly where it was. The office was located at the corner of N. 9th and Adams Streets. Looking at Google maps, I see an area a bit northeast of that place where there appears to be a small yard. There is an area there that looks like it may have housed the T/T and roundhouse, but that’s just speculation on my part.

I can only bet on what would be in that water/ slug.
And smell?
Never seen one my self.
Boudreaux, I’ve seen a lot of turntables over the years, even taken a spin on several of them. But this is the only one I’ve seen filled with water. Obviously the drain was stopped up and nobody seemed willing to fix the problem. Yep, no telling what lurked in that mess! 🙂
