104 units were delivered to DSB, 45 MX and 59 MY, 37 units for NSB and 20 units for MAV. All the DSB locomotives have the A1A-A1A wheel configuration. The DSB MX locos were fitted with the less powerful twelve-cylinder engine.

Also the NSB Di3b locos have the A1A-A1A bogies. With a maximum speed of 143 Km/h, reduced later to 105 Km/h, the Di3b class was the fastest class of this type of locomotives. Only a little bit slower was the SNCB class 204, which was allowed to run international passenger trains with a maximum speed of 140 Km/h from Brussels to Paris and Köln.

All the AFB locos are equipped with the 16.567C engine and CoCo bogies. The SNCB locos were splited into 3 different classes. Class 202, later 5200 for local passenger trains, class 203, later 5300 for heavy fright services and class 204, later 5400 for international passenger trains. The CFL 1600 locos are identical to the SNCB 202 locos.

The NOHAB loco with the number 2402, today NSB Di3 643 was build as an broad gauge loco, to serve the VR for tests. In hope that VR would buy NOHAB Diesel locos they began to build broad gauge locos. As the VR decided not to buy NOHAB locos, the production of the 2 locos with the serial numbers 2416 and 2417 was nearly terminated. These two locos and the test loco 2402 were transformed to normal gauge locos , but only the A1A-A1A wheel arrangement was possible. NSB bought these locos to form the Di3b class.

The last loco of this type which was build is the NSB Di 3 633, build in 1969.

In 1979 the SNCB locomotives started to receive a new, modified cab at SNCB Salzines factory. 5306 was the first loco, which was modified. Referred to ass a floating cab, it reduced the cab noise and insulated the driver from draughts. The locos have no longer the classic American style. Only the 5404, today 204.004 loco was saved from this action. It is planed to save this loco for the future Belgian railwaymuseum.

The first loco, which was radiated, was the SNCB 5405 in 1982, after an accident at Andenne on 09.10.81.

The CFL was the first company, which took out of service all its locos. After the 1601 in 1985, the three other locos loose services with the winter timetable 94/95.

In 1995, 1602 was sold to Märklin Belgium, but in 1998 a Belgian private person, who gave it to the PFT-TSP railway association, bought it. In the winter 98/99 the loco was repainted into SNCB green colors and renamed 202.020. The logic behind this transformation is that the loco was originally destined for SNCB, but CFL bought it in last minute before delivering to SNCB.

Loco 1603 was sold in 1996 to the Belgian association " Vennbahn" , which is a museum railway association which runs trains on her own lines in the area around Raeren.

The 1604 ist the only one which is still in Luxembourg. The loco is now owned by the luxembourgisch government and classified as an technical monument.

In Denmark all the MX locos are out of service at the DSB, most of them were sold to private Danish and Swedish private companies. Only the first MX loco, the 1001 is still in use for museum trains. Also the MY locos in use at the DSB company looses more and more work. In 1999 ten MY locos were sold to Germany. The NEG classified them ass class V 170 in their stock.

After the disaster with the new Di6 class, some Di3 were refurbished in 1998, but end 2000 they were retired from passenger duties and replaced by the new railcars BM 93. The Di4 and Di8 locos took over the last fright duties on the Nordlandsbane in summer 2000. A very said and tragic day in the life of Di3 was the 03.01.2000, when Di 3 625 and a DMU class BM 92 collided on the Rørosbane near Åsta. 19 people were killed and several people were serious injured.

Also at the MAV there are a few M 61 still in use. After the crash of the museum loco M 61 004 in 1999, the M 61 001 and M 61 020 will now be conserved as a museum locomotives.

The last regular train hauled by an M 61 was train 974 between Székesfehérvar and Tapolca on 11.11.2000. On 22.12.2000 the last locos in use, 61 006, 61 010 and 61 019 were hauled by M61 020 from Tapolca to Budapest were they are stored now.

The last regular use of Di 3 in Norway was on december 26, 2000. Train 2302 Trondheim - Hamar was hauled by Di 3 629, 3 623 and 3 628. On the return, train 2303 Hamar - Trondheim was hauled by 3 623, 3 629 and Di4 655.

In January 2001 4 locos, 3 619, 3 633, 3 641 and 3 643 were bought by the norwegian government and send as donation to Kosovo.

After the 07.01.2001 only one daily freight train between Århus and Herning is still hauled by an MY in Danmark.

All these information’s are without guarantee.
