Class 628.4 / 928.4 | TrainsDepot.org

The second series was able to benefit from the everyday experience that had been gained in using the railcars. In 1992 Düwag (formerly Waggonbau Uerdingen) proposed the Class 628.4 railcar, which once again had technical improvements and other refinements. The power of the diesel engine was increased by about 20% by using "charge cooling". The lower window panes on the doors were omitted as they had occasionally been broken on its predecessors, the Class 628.2, by flying stones. In order to install a double door at the close-coupled end of the two coaches in the multiple, they were both extended in length by about 50 cm each. Between November 1992 and Januar 1996 a total of 309 railcars were built, of which several were delivered to other railway companies, including those in Luxembourg (see Operations) and Romania.

The first vehicles in the regions of Rhein-Ruhr and the Southwest were given a modernisation of the interior. The railcars were matched to the current DB interior design. The seats have blue cushions and arm rests made of beech wood, the walls are silvery, the luggage section completely white, the windows are equipped with emergency hammers. The colour of the entrance area is white, and in some cases larger bicycle sections were installed in the centre of the carriage. On some of the units, the doors were also fitted with sensors.
