DSB Class F No. 654 is one of the most historically significant survivors of the class. Unlike its sibling 655, No. 654 was preserved, spent decades operating on a heritage railway in Germany under the nickname "Julchen", and is currently in storage awaiting its planned preservation in the UK.

Production & DSB Service (1949–1970)
* Origin: It was manufactured by A/S Frichs Maskinfabrik og Kedelsmedie in Aarhus, Denmark, in 1949.

* Identification: It holds Frichs Works Number 358 (built immediately prior to No. 655).

* Station Assignments: According to Danish rail history records from Jernbanen.dk, its primary operational bases included:
* 1950–1961: Nyborg
* 1963: Odense
* 1968–1969: DSB's 2nd District

* Retirement: The engine was officially withdrawn from active DSB commercial service in 1970 and temporarily stored in Padborg and Tinglev.

Transition to Heritage & Exhibition (1975–1977)
* Museum Showcase: In April 1975, the locomotive was temporarily placed in the town square of Odense (Odense Torv) to mark the grand opening of the Danish Railway Museum. It remained on display there until late 1976.

The German Era: Angelner Dampfeisenbahn (1977–2020)
* The Move: In 1977, the engine was sold to the Angelner Dampfeisenbahn heritage railway based in Kappeln (South Schleswig), Germany.

* "Julchen": It was affectionately nicknamed "Julchen" by its German operators. For over 40 years, it was a staple attraction, pulling tourist trains between Kappeln and Süderbrarup.

* Storage: The engine last ran under steam in 2017. In 2020, it was sold to a culture-shed group in Neumünster (Interessengemeinschaft Kulturlokschuppen Neumünster) where it currently remains stored

* Future: Due to the exciting new exhibitions due at Neumünster, a new home for 654 had to be sort. Nene Valley Railway was offered the opportunity to purchase the locomotive due to its impressive status as an international continental heritage railway and having a sister engine 656 already based there. Unfortunately, Nene Valley Railway weren’t in a position to purchase the locomotive so a new society the European Steam Preservation Society was formed to purchase, overhaul and maintain 654 with permission for it to have a permanent home at Nene Valley Railway
