Multi-Functional Termnals with 6.5" were deployed in trams and metro projects already in the mid 1990s. The first MFD 5 was delivered in 1996; the displays are in their third generation by now. The use of the MFT 5/2 as successor to the MFD 5 virtually increases the service life of the on-board computer. Thus, DEUTA now covers a delivery period of 20 years with identically constructed displays.
