Since 941

Elloket Da is a Swedish locomotive type that was manufactured by ASEA between 1952 and 1957. A total of 93 were built, which became SJ's new universal locomotive in the 1950s and were used in both passenger and freight traffic. The Da locomotive represents the end of an era of coupling rod locomotives before bogie locomotives took over.

History:

After the last D locomotives were delivered in 1943, SJ realised the need for more electric locomotives in connection with increased electrification of the railway network. The choice fell on a further development of the proven coupling rod locomotive, which resulted in the Da locomotive. These locomotives were used throughout SJ's network for both passenger and freight traffic. During the 1970s, the locomotives underwent modifications to improve running characteristics, including the change to rubber-sprung SAB wheels and improved cabs. By the end of the 1980s, Da locomotives began to be withdrawn from service, and by the mid-1990s, SJ had cancelled all its locomotives of this type.

Design and use:

Da locomotives were a modernisation of earlier D locomotives, including a new type of engine and a more modern look with rubber-framed windows. They were equipped with multiple coupling, allowing up to three locomotives to be coupled together to handle heavier trains. Despite their versatility, the locomotives were criticised for putting abnormal wear on the tracks due to their rigid drive axles.

Preserved specimens:

Several Da locomotives have been preserved as museum vehicles. The Swedish Railway Museum has the first locomotive delivered, Da 790, as well as two other locomotives (820 and 888). Bergslagernas Järnvägssällskap also has a Da locomotive (896). Netrail restored Da 941 to its original condition in 2013, and it was later purchased by the Nässjö Railway Museum.

The Da locomotive marks the end of an era of coupling rod locomotives in Sweden and is an important part of the country's railway history.
