Testing of three prototype trains began in 1982 on the Alb Valley Railway.[4]

First and second batch trains were built by multiple manufacturers, including Duewag, Siemens, and Bombardier.[5]

The first DT8.10 set was delivered in April 1999.[2]

20 Stadler Tango-based DT8.12 were ordered in 2010.[6] Additional 20 sets were ordered in 2014,[7] and further 20 sets were ordered in 2017.[8]
