Y-train
diesel multiple unit

The Duewag Y is a series of diesel multiple units (DMUs) manufactured between 1965 and 1988 for Danish rail operators by the West German company Waggonfabrik Uerdingen. A total of 160 cars were built: 76 motor cars, 23 trailer cars, and 61 control cars.
Introduced in 1965 by Danish private operators and later in 1984 by DSB, the Y-type units began being phased out in the 1990s. DSB ceased operations in 2010, and the last run on Danish rails, by a private operator, occurred in 2012. All units were scrapped except one preserved for museum purposes and another exported to Poland in 2008. In 2010, this unit operated in Kuyavian-Pomeranian Voivodeship under Arriva RP, but it was later placed in long-term reserve with no plans for reactivation.
History
In the 1960s, Danish private rail operators began retiring steam locomotives on local lines, seeking diesel replacements to cut costs. A consortium of private rail companies agreed to jointly fund a bulk order. After testing various models, they selected Waggonfabrik Uerdingen in West Germany for its superior offer.
Between 1965 and 1988, 160 Y-type cars – 76 motor cars, 23 trailers, and 61 control cars, including 9 motor and 5 control cars with dual cabs – were delivered in eight batches to 14 private operators and DSB. Production occurred at Düwag's Krefeld plant, with final assembly by Scandia in Randers.

Why this record matters
“Y-train” is worth following because a concise public description often conceals a longer documentary argument. Here, Y-train, diesel and multiple provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 15, 2025. The linked authority identifier is Q1143325. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1965, 1988, 1984 and 2010.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
