Unique but Welcome Visitor. Due to a derailment in Hamlet, NC, I137 was rerouted down the Monroe Sub to Greenwood, SC. Initially, I had heard it would proceed down the McCormick Sub toward Savannah, but there apparently are height restrictions on that Sub that would preclude that routing. So the train was routed south down the CN&L through Cayce, SC, and then down the Columbia Sub to Savannah. Here, it proceeds through Clinton toward Dover Connection where it will get on the CN&L.
