Siemens 462 018 parked in Dortmund Hbf on 31st of March 2019.

Class 462 for RRX-services is owned by its producer Siemens. The public traffic organisation by the region - VRR - pays Siemens to provide the class to the operators of RRX (Abellio and NX) and Siemens guarantees a very, very high disposability (rumors says "100% of time for 82 units"). The operators are named below the RRX-logo in white letters on grey background. Units 016 - 019 actually are known as NX-units.
Again: 100% disposability? It seems Siemens had a little problem and solved it with a big white sticker, as the NX-units will come in service not untill summer 2019.
