[1] On 1 January 1994 the ownership of these vehicles was transferred to the DB's legal successor Deutsche Bahn and its subsidiaries or business areas.

The first series of 25 three-coach units was delivered at the time when so-called "pop liveries" were in vogue and so they were painted in stone-grey and orange.

Immediately following the first batch were the 15 units of the second series delivered in 1975 and stabled at Brunswick locomotive depot.

During some timetable periods they also called at Lemgo, Münster, Nordhausen, Osnabrück, Oldenburg, Rahden, Uelzen and Wilhelmshaven.

Meanwhile, following the transfer of numerous lines to private firms as a result of competition, and the delivery of the Class 648.25 to DB Regio, the Brunswick DMUs have largely withdrawn from these classic routes.

The Nuremberg 614's are underway in the Upper Palatinate (Oberpfalz) and in Franconia (Franken), working such routes as Forchheim–Ebermannstadt, Fürth–Cadolzburg, Fürth–Markt Erlbach and Nuremberg–Simmelsdorf-Hüttenbach/Neuhaus an der Pegnitz.

Here too only three-coach trains are used, whilst previously several 934's were stationed at Nuremberg in order to be able to form four-car multiples.

As part of modernisation in the mid-90s a warning tone device was retrofitted and - unlike the 624 - also an anti-jam system.

Shortly after the turn of the millennium several 614's were converted to TAV (technikbasierte Abfertigungsverfahren) automatic door operation.

The control of all displays in the train was achieved by entering the destination code number into Brose entry devices that are installed on every driver's console.

The colour of the seat covers as well as the imitation leather arms and headrests varied, being either red-brown or green.

During the course of the modernisation programme the 614's were given the first double-decker coaches delivered to the old Federal states and the y-coaches of well-known design with beige wall coverings and light green fabric-covered individual seats, some arranged facing each other, others all facing in the same direction.

Unlike the 624/634 the 614 was given an additional thin blue decorative stripe above the line dividing the colours which lent the vehicles a more dynamic appearance.

Almost all 614s were initially painted light grey and mint green for the redesign and, later on, traffic red and white.

The only exception is unit 614 005 + 914 003 + 614 006 which was painted in gravel grey and orange on modernisation and preserved the 'pop' colour scheme into the new millennium.
