Sole Survivor- UP GP38-2  

It's not the last one of its kind. Not even close: UP has _dozens_ of unrebuilt GP38-2s and, as far as can see, the GP38N rebuild programme ended in late 2019.

Me too

38-2..for some reason my auto correct changes it to 39-2 if I put GP in front of it😂😂😂😂

That’s cool, I just saw UPY 587

Thank you!! I appreciate it

GP40s like to slip too much, have more maintenance, and use more fuel than GP38s. They get gutted to maintain SD40s.

Good question, I’m not sure to be honest. Both UP and BNSF in my area have little to none of them so that’s beyond my expertise

Thank you Steven!!!

Thank you!

Thank you!!!

You’re welcome!!!

Take a guess

Thank you!

It isn’t

​@@unionpacificomaha definitely is

I was going to say the same thing, but you beat me to it. That is definitely a Canadian tuned K3. In Detroit, I heard these regularly on older CP and CN units.

Thank you Owen!!

Correct

N is just denotes that the unit had been rebuilt

The original EMD locomotive was the GP38, built between 1966 and the end of 1971. From 1972 onwards, EMD build the locomotives to a new spec and called them GP38-2. The dash-2 locomotives had a slightly redesigned truck, and a few other minor differences, but the main difference was a modular microprocessor-based control system. That increased reliability, made repairs easier and also had better wheelslip control. Many original GP38s were rebuilt as dash-2s. Any other designation isn't an original EMD model number. Many railroads have rebuilt locomotives and upgraded their equipment over time. Southern Pacific usually added "R" to the model number to denot this; CSX calls rebuilt dash-2 locomotives dash-3s. Union Pacific rebuild a lot of their GP38-2s, GP40-2s and SD40-2s (and a few other models) in the period 2010-18 with refurbished engines and electrical components and a new microprocessor control system from ZTR Control Systems called NEXSYS. These locomotives are denoted GP38N, SD40N, etc.

Thanks Dan!

Thank you!!!
