The series 460-462 are electric multiple units built by Siemens and belong to the so-called "Desiro" family. The Desiro ML (for Mainline) are single-deck trains and were first used by the operator Transregio on the West Rhine Railway at the end of 2008.

In 2016, Siemens presented the "Mireo" (class 463) as the successor of the Desiro ML. The first trains have been in passenger service by the end of 2020 and quickly got the nickname "carp" due to their front design.
