A special variant based on Class 628.4 was procured for duties on the hilly Alzey–Mainz railway. Five multiples were bought, both coaches in each pair being motorised. These trains were designated as Class 628.9/629, but apart from having two power cars were identical with the Class 628.4. Due to their higher maintenance and operating costs there is no likelihood of the 628.9/629s being procured for use on lines which are predominantly level. The 628.9/629s do not need double the fuel of a 628, because the two power cars have shorter periods under load.

A sixth set has been procured by motorising a driving coach. Another set was formed in 2004 from two 628.4 sets whose driving trailers were damaged in accidents. This set has no first class accommodation, as the internal layout has not been changed.

Two more 629s appeared in 2004 based on former 628.2s, that work with another 628.2 instead of a driving car.

Two sets have been stationed at Ulm Hauptbahnhof with running numbers 628/629 340 (629 340 ex 628 341) and 628/629 344 (629 344 ex 628 349). Since 8 August 2008 Regio Südwest also has a set numbered 628 301/629 301 (629 301 ex 628 257), which should follow the other two.
