The building across the parking lot from mine is having grease pits installed for their two resturants' waste grease. They've trenched the parking lot revealing lots of interesting things, including what appears to be a bit of small code rail.
Here's a close up
The interesting bit is that my building and the one this rail is nearer to used to be warehouses back in the day. We have 18" thick solid concrete flooring! A real bugger to run network wire through
Anyway, this picture shows how the rail pairs up next to their building.
This is downtown Little Rock in the old warehouse district, now it's nearly all office spaces and resturants. In the following picture I've marked in red where rail used to be and in blue where it could have been. Interesting to think about.
Previous construction in the area, which I don't have any pictures of, was when they were installing rail for our new trolley system. They unearthed decades of various roadbeds includng cobble stone and brick paving along with several layers of various concretes and asphalts. It made for quite an interesting time line of downtown Little Rock's transportation.
