Development
The first prototype ES 64 P was built in 1992, as Deutsche Bahn AG was expected to issue a large order of locomotives as a replacement for the ageing Einheits-Elektrolokomotiven. The external appearance was similar to the earlier Siemens/Krauss-Maffei made dual voltage Spanish RENFE Class 252, delivered in 1991, which in turn used three phase asynchronous drive technology introduced with the DB Class 120. The prototype was used for extensive tests in some countries in Europe (Norway, Spain, Portugal, Germany). The prototype was given the DB reporting name Class 127. It is still in service with Dispolok, a formerly Siemens-owned locomotive pool for on-hire use.
