EMD GP50

An EMD GP50 is a 4-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). It is powered by a 16-cylinder EMD 645F3B diesel engine, which can produce between 3,500 and 3,600 hp (2,610 and 2,685 kW). 278 examples of this locomotive were built by EMD between 1980 and 1985. BN 3110-3162 were all delivered with five cab seats, the final five of these having the cab lengthened 23 in (584 mm) vs. the standard EMD cab. The GP50 retains the same overall length of 59 feet 2 inches (18.03 meters) as the EMD GP38, EMD GP38-2, EMD GP39, EMD GP39-2, EMD GP40 and EMD GP40-2.

In 2015–2016 the Norfolk Southern Railway rebuilt 28 GP50s into the low-emission GP33ECO.[1] And in early 2016, Norfolk Southern rebuilt one GP50 into their first GP59ECO. These units, most of which utilized GP59 cores, have similar specifications as the earlier GP33ECO program but have been built without public funding contributing to their construction.

gollark: I got a "Takeout" archive a while ago, and it has rather a lot of stuff in it.
gollark: What data?
gollark: My stuff (mostly) runs dnscrypt-proxy, which works as a local DNS server which forwards requests to DNS over HTTPS/TLS servers.
gollark: I just run an adblocker on basically everything.
gollark: Me too. Their lack of respect for privacy and tentacles throughout the web are very irritating.
