Because after the Second World War, the British military governors of Schleswig-Holstein ("Regional Commissioners", originally Hugh Champion de Crespigny) lived in the Altenhof manor house, but had their seat at “Somerset House” in Kiel, the line was repaired relatively quickly after the war and services resumed between Kiel and Eckernförde with a morning and an evening services and a single stop at Altenhof station.

The former engine shed was replaced by for a parking lot after the closure of the port railway.

[7] From 1972 to 1999, Eckernförde station was serviced by individual Durchgangszug (a type of express) and Intercity (IC) trains on the weekends.

The IC trains operated, inter alia, on the Eckernförde–Koblenz (initially from Flensburg), Cologne–Eckernförde and Düsseldorf–Hanover–Eckernförde routes.

In the first years after the opening of the resort of Damp 2000 in 1972, special IC trains ran from Cologne to Eckernförde and back for weekend getaways.

The original entrance building of Eckernförder station—built in 1880/81 and expanded several times since to about three times its original size—was demolished in 1973 after, a few months earlier, serving as a film set for part of the television adaptation of Hans Fallada's novel, Bauern, Bonzen und Bomben [de] (published in English as A Small Circus).

Shortly before, the freight yard had been moved to the south of the entrance building; this area is now used by the bus station.

This would also provide space for a cinema and retail shops alongside the railway service areas and the office of the Bahnhofsmission (a charity helping travellers and the needy at stations).
