The Columbia & Greenville Railway was built around 1845. It was amoung the earliest railroads in South Carolina. I think it used some threadless but I'm not a threadless insulator hunter and it is impossible to find the threadless anyways. The regular 4 crossarm poles along the track were removed about 20 years ago. I did find old pole stumps and lots of glass shards around the tracks. No threadless, sorry. The poles had some CD 121 Brookfield, CD 151 Brookfield, CD 154 Hemingray and WT, and CD 155 Hemingray. That's as much as I found out by the shards. I left a pile of glass near the road. It was a ton of shards of 42s!

In this picture is a top to a common, busted CD 121 Brookfield that was mowed over by a tractor or two.
