Locobase 2477 describes the 11 Swedish F-class four-cylinder compound Pacifics produced by Nydquist & Holm that served as that country's express passenger power from 1914 until the SJ electrified the main lines in the early 1930s.

Although the DSB had already begun its own transition to electric and diesel traction, the railway made an exception in 1937 when the F class became available The DSB knew the F class as a powerful and reliable design, the SJ set an unbeatable price equating to the scrap value, and delivery could begin immediately. All eleven entered service between Autumn 1937 and Spring 1938.

Two years later, the Third Reich occupied Denmark as part of its 1940 offensive surge in the West. German demands for substantial tonnage increases on the DSB led the occupiers to require the railway to order new E-class engines from Frichs. The first thirteen arrived in 1943-1945.

German occupation and Western Allied air attacks on Danish infrastructure delayed the Danes' program of transition from steam to other forms of traction. Instead, they ordered further E class deliveries in 1947 (seven) and 1950 (five) brought the total to 25. Over the next fifteen years, E class engines would haul a variety of trains, in part because the diesel replacement that began in 1954 with the entry of the first MY diesels affected other older classes first.

But by the early 1960s, E-class phaseouts began accelerating while some services still used them as late as 1966 and 1968.

Jernbane noted the few differences between the original F class and the Frichs E class. The latter weighed a bit more, had a welded tender instead of the F-class's riveted verion and added a steam dryer.

During its years under German control in World War Two, the DSB realized that they needed more adhesion in the locomotives pulling their expresses. And they knew they wouldn't be able to order new equipment. So Copenhagen shops retained the frame from the P-class 4-4-2s, used the firebox already installed in the H and R classes, trailing auxiliary axle from the O and S classes and created the Pacific shown here.

Tests of the 904 in 1943 were sufficiently encouraging that the railway went ahead and converted the 930. For the first few years, the conversion looked like a flop because the boilers didn't generate enough steam. Jernbane,dk reports that postwar studies showed simply that inexperienced stokers and poor coal starved the firebox of the calories it needed. As peace liberated Denmark, coal quality improved, and the stokers received better training, the class performed up to their promise.
