Somewhere on the D&H, I'll bet. That bracket signal makes it so, I'd say. Dual control unit, tu. HAWG never had to sit on the WRONG side, unlike what would happen in later years.
Uh, any other thoughts that I have may be better suited for another location, but many of those companies that the units are sublettered for were operated as subsidiaries of the Southern long before diesel power. I believe the Central of Georgia and the original Norfolk Southern may have been some of the last to come under the Southern green light to investigation way of thinking. The CRN (Carolina and Northwestern) was another road that the Southern swallowed up and when the new Norfolk Southern came into existence, the old power was sublettered CRN.
Here's a fine example of the original Carolina road's one Alco, apparently a Southern experiment with Alco power.
That was the only Carolina and Northwestern Alco. Not NS, Carolina and Northwestern.
If you're sitting on the left side operating a locomotive, you're on the wrong side. We all knew that and we all hated it with a passion. On reflection, I don't think I hated it as much as I hate Steve Lee controls.
You're going to tell me that the Southern didn't really operate those roads for many years before LAMCO? OK. I've always thought otherwise, the CNO&TP being a example.
