In 1996, Deutsche Waggonbau designed the double-decker DB Class 670, which, however, did not satisfy its operational requirements. As an alternative, the DWA developed the single-deck railcar LVT/S (DBAG Class 672), which was designed to be more robust and suitable for full-track use. With the acquisition of DWA by Bombardier Transportation a further construction was omitted as well as an extension of the vehicle range to a control car or a twin-railcar variant.
In 1998, some vehicles were used by the Butzbach-Licher Eisenbahn on the Friedberg-Friedrichsdorf railway line because the ordered GTW 2/6 could not be delivered on time.
Originally the vehicles were called KEG VT 3.01 to VT 3.18. Since the takeover of the vehicles by DB Regio in the year 2004 they are listed as 672 series. In the inventory there are the vehicles 672 901 to 904, 906 to 911 and 913 to 920. 672 912 is parked after a fire[2] and 672 905 was retired on 27 November 2014.[3] From April 2006 to December 2006, the vehicles were not used because of a damage of the frame for safety reasons until their renovation. Since March 2012, 672 919 and 920 have been stored as pre-production models. They have solid shafts for which there are no test instructions that meet the requirements of the Federal Railway Authority (EBA).
