DSB
MY 1126 was at that time withdrawn, and apparently at Odense for use as dead weight for Class EG testing.
As the longer term readers may recall, I am rather favourably inclined towards the NOHAB GM locomotives, following those remaining in Hungary, most recently in
2016.
Class MY, assembled in Sweden between 1954 and 1965, was based upon the
EMD F7 design, with power unit set at 1700 - 1950 hp and A1A-A1A bogie arrangement. All but the first had bodies constructed by
Frichs in Denmark, and shipped to Sweden for assembly.
1126 was built with a 16-567C engine set at 1700 hp, delivered on 31st August 1957. The 'graffiti' paint scheme was applied in 1988 for a programme of ATCS testing in 1989-90, this using an
IBM PC XT.
"Train Brain could be used to control the train. The stretch and train data - climb conditions, train weight, rolling resistance - could be programmed into the computer and it could then determine the most economical driving. DSB anticipated up to 15% energy savings compared to traditional, manually controlled driving. Train Brain could be pre-programmed with the stop pattern for driving, and the train would function as completely driverless, or you could remotely control the train via the radio connection and Train Brain.
The computer could monitor the functions of the locomotive, including a troubleshooting program. Train Brain could also be used to transfer error data to a central database in order to optimize "preventive" maintenance.
In the case of freight traffic, the locomotive's computer could be provided with information on carriage use and destinations, and the reports from the train are collected centrally in a computer program that could optimize the use of the carriage.
When traveling by passenger train, Train Brain could include a space reservation system and a passenger information system.
A long trail at the south end of Copenhagen's Godsbanegård was reserved for the experiments with ATCS. Along the way, several "stops" were built where the test train was to stop. Furthermore, some special baliser / transducers were laid out for ATCS. The ATCS locomotives were also equipped with transducers so that the position of the train on the line could be checked at intervals; moreover, A TCS, like ATC, was based on the measurement of distance by counting the number of wheel revolutions. In December 1988, the first driverless test run was carried out, with MY 1126 controlled solely by the mounted computer. The locomotive drove back and forth on the test section following the programmed roadmap and stopped at the designated "stops"."
Returned to normal traffic in 1992, and in February 1994 was leased to Norway to cover Winter Olympics traffic, and where the NOHAB Di.3 was similar. Shunter platforms added in 1995. Removed from traffic in January 2000 at Copenhagen. Reactivated in 2002 and sold to
DJK (Danish Railway Club).

DSB MY
1152 is from the later batch, fitted with a 16-567D engine set at 1950 hp. Delivered to DSB on 15th March 1965. Stored in January 2000, and withdrawn in December that year. Sold to VLTJ (Lemvigbanen) as
MY 28 and operated with them until 2008, when merged to the associated MjbaD (
Midtjyske Jernbaner = Central Jutland Railways) for whom
it still operates.
The following locomotives are
1146 and likely
1150.

25. May MY 1126-1146-1150 and 1152 arrived in Odense in order to be used for dead weight for these testings... (29. May 2000, source
dk.fritid.jernbaner and more).
| | On 30. May EG 3104 used 4 MY-locomotives as dead weight, when running to Slagelse on train FM 8836. The MY's where MY 1152 (idle) + MY 1146 + MY 1150 + MY 1126 (3 dead engines)." |
3007 was new in 1985, and continues to operate for DSB.
The majority of the class now operate in Romania and Bulgaria. DSB intend to replace their remaining locomotives by the end of 2021, through the new Vectron deliveries.
1152 may have been stored, but it appears to have been a warm storage, as here it is about to pilot an unidentified MZ loco out of Odense in the Copenhagen direction. Probably 28th June 2000.
