This is a much cherished European version of the early American diesel engines.
I think that the sad look of this engine gives a challenge for Lego-builders. Here is my first 7-wide try made with LDD:

Here is some history of which you can get keywords to look for reference pictures. DSB MY is the diesel engine made by Swedish company Nydqvist & Holm Ab (NOHAB). NOHAB round-noses were based to the American diesel engines. The models for NOHABs were American E- and F-series from 1930s and Australian Clyde AA16 from 1950s. For European needs NOHAB round-nose has been designed two-way driveable and for that reason with two cabins. Differing to the American equivalents NOHAB has also rounder roof, ditch lights, lower safety nose and larger windscreen. I think that all NOHAB round-noses had American diesel motor made by GM.
NOHAB round-noses were manufactured between years 1954–1969 to Denmark 104 pieces for DSB MY-series and MX-series, to Norway 35 pieces for NSB Di.3-series and to Hungary 20 pieces for MAV M61-series. Danish MX-series is lighter than MY-series but it has also 6-axels.There were also manufactured by license same type engines to Belgium and Luxembourg. Norwegian, Danish and Hungarian State Railways gave up these engines from operation between the years 1985–2001. However NOHAB round-noses are still in operation in great numbers for example in Sweden by private railway companies.
I am also interested in building this engine (and in 6-wide). Because NOHAB round-nose engine with factory number 2402 has operated in Finnish State Railways as experimental engine KDs1 between years 1958–1960. That specific engine was finally sold to Norway as NSB Di.3 number 643. In Norway that engine operated to the year 2000. I think it is still in operation in Kosovo Railways as number 008.
