Intermountain N Norfolk Southern SD40-2

I found an Intermountain N Norfolk Southern SD40-2 at a good price:
The paint scheme puts it in the general time frame I'm interested in, since the full white stripe on the frame would have been added to the loco in the late 2000s prior to the 2010 FRA mandate. This would also have been during the time NS ran short hood front. However, the NSDash9 site doesn't list it as a loco that ever received the solid white stripe. NS 3201-3328 were former Southern Railway units that retained their numbers in the 1982 NS merger. However, all of these have since been retired or rebuilt into SD40-3s with low short hoods.

Nor, apparently, did 3224 ever get the "horsehead" scheme. Locos in the 3200 series have since been replaced by AC44C6M rebuilds from 9-44CWs.

The model has truck siderrames with two brake cylinders, which is correct for former Southern Railway units on NS. Original Norfolk and Western SD40-2s had a third brake cylinder above the center journal. However, only 11 N&W SD40-2s had high short hoods, so this Intermountain model is much more typical of NS SD40-2s, at least prior to Conrail.

The model has ESU LokSound 5 DCC and sound. Following my preference, I set acceleration-deceleration CVs 3 and 4 to 0. I also found that I needed to set CV 2, starting voltage, to 20 to get the loco to start rolling on speed step 1. Once I did this, its performance matches other DCC equipped locos from other manufacturers.
