This short line was involved in litigation with the "Cincinnati, Hamilton & Dayton" at Lima OH in 1909-11, but it seems to have fallen off the radar. I can't find any book or map mentioning it, apart from the Ohio Transport Commision lists. Has anybody else heard of it?
Just a guess on my part, but I'd suspect that it was one of the predecessor properties that became part of the DT&I. Here's a link that details the history of the DT&I.

Note that a predecessor was the "Detroit & Lima Northern" while another was the "Ohio Southern" Perhaps a mis-entry into the records? Or perhaps the Lima extension of the Ohio Southern (from Springfield OH to Lima) was initally called the "Lima Southern"?
