Deutsche Bahn awards certificate of maturity for IFE entrance system
The Knorr-Bremse division IFE has received the DB certificate of maturity for the E4 entrance system after two years of operation in a double-decker Deutsche Bahn train. IFE is the first to receive this certificate. In autumn of 2013, DB and IFE agreed to pursue new paths when introducing new products onto the market. Products should only be established on the market if they have actually reached maturity and all teething problems have been resolved.
