Interesting you should post a photo of the 4610 (the only locomotive in the NS fleet painted in those colors). My sons used to work out at a grocery store where the Ft. Wayne mainline crosses SR 18 here in town. Very common to see trains "holding" just west of the crossing waiting to get in to the yard.
Rob called one afternoon telling me the 4610 is on the lead and holding by Hogues Market. Since I have a model of that locomotive, I grabbed it, and off I went. Got out there, took a photo of the model setting on the deck of the real one and got ready to leave. Well here comes the crew asking what's going on. I told them. The engineer then opined as how "....these green locomotives are a mixed bunch, some of them run real good, others ain't worth a damn....".
OK, whatever, no point in arguing with the guy, just chuckled to myself and left.
