Well almost.. Another fine shot by Odd Arne Loeshagen.

Very nice! I once travelled on a passenger train in the '90s, I think from Bodo to Trondheim behind a pair of these - a memorable trip!

Do they still have the 567 power unit?!

Very nice, remember them in Denmark and I've seen one in Hungary.

Good action picture.  They also operated in Sweden.  Gerry

I think that is a NOHAB, not an F unit, you can see the mirror on the trailing end cab.

NOHAB must mean "no habitation."  To make dese creatures, the Swedes just glued an extra cab on em.

Reindeer glue?

Skol to you and Odd.

Basically it is a double-ended F7.  Info from https://en.wikipedia.org/wiki/NSB_Di_3

"NSB Di 3 is a class of 35 diesel-electric locomotives built by NOHAB for the Norwegian State Railways (NSB). The class was built between 1954 and 1969, and delivered in two series, Di 3a and Di 3b. They are based on the Electro-Motive Division F7 and are equipped with EMD 567 engines. They have a distinct bulldog nose and were numbered 602–633 (a-series) and 641–643 (b-series). The locomotives had a prime mover that gives a power output of 1,305 kilowatts (1,750 hp). The a-series has a Co′Co′ wheel arrangement, while the b-series has (A1A)(A1A). The b-series has higher top speed, but lower tractive effort.The class was the dominant locomotive on NSB's unelectrified lines. It was ordered as part of the company's dieselization of services during the 1950s and 1960s, and was initially used on the three mainline routes of the Bergen, Dovre and Nordland Lines. In the 1960s the Bergen and Dovre Lines were electrified and the Di 3 units transferred to smaller lines, such as the MerÃ¥ker, Valdres, Røros, Solør and Rauma Lines. They remained in service with NSB until 2001, five years later than planned due to NSB returning their successor, the Di 6. The units are still in use by the private operator Ofotbanen, the Kosovo Railways, an operator in Sicily, and the Norwegian Railway Museum. The class is similar to the DSB Class MY, NMBS Class 52–54, CFL Class 1600 and MÁV M61."

"Specifications
The Di 3 was built by Nydquist och Holm of Trollhätten, Sweden, as part of a series of GM EMD AA16 locomotives in Europe. They are technically similar to the DSB Class MY of Denmark and the MAV M61 of Hungary. The locomotives are powered by a 16-cylinder EMD 16.567 C or E engine that has a power output of 1,305 kilowatts (1,750 horsepower) at 835 revolutions per minute (rpm). The engines power an EMD D32 or D12 generator that feeds six ASEA LJB76 or LJB84 motors on a Di 3a. The Di 3b is equipped with four EMD D40 or D77B motors. This gives a tractive effort of 265 kilonewtons (60,000 lbf) for the a-series and 176.5 kilonewtons (39,700 pounds-force) for the b-series. The motors have a power output of 1,100 kilowatts (1,500 horsepower). The maximum speed is 105 kilometres per hour (65 mph) for the a-series and 143 kilometres per hour (89 miles per hour) for the b-series.[5][16]The steel bodies are 18.60 or 18.90 metres (61.0 or 62.0 ft) long. The longer length is for the three b-series units and the two a-series locomotives that were made in the batch, originally intended for VR. The a-series has a Co'Co' wheel arrangement, while the b-series has a (A1A)'(A1A)' arrangement, where the center of the three axles on each bogie is unpowered. The wheels have a 1,016 millimetres (3 ft 4.0 in) wheel diameter and the locomotives have a weight of 102.0 tonnes (100.4 long tons; 112.4 short tons) for the a-series and 103.0 tonnes (101.4 long tons; 113.5 short tons) for the b-series. The trains can be run in multiple with the Di 4, Di 6 and Di 8. All the Di 3 engines featured a bulldog nose, the only locomotive type in Norway to do so.[16] The locomotives were at first delivered in a dark green livery, but during the 1960s this was changed to red, and the last delivered units never had a green scheme.[6]"

Tusen takk for the additional information.

Indeed, but riding on three-axle trucks, instead of the two-axle trucks of the F7.

Also, the 628, is in MoW service with Banenor, the state-own infrastructure company that owns the tracks and associated infrastructure of the Norwegian rail system.

Heimdal,

I remember seeing these on passenger trains stopping at Vinstra, on the Dovre line, while visiting my aunt in January, 1967. As I recall, their days on that line were already numbered because they were in the process of stringing catenary through there at that time.
