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.

Famous quotes containing the word development:
“Every new development for the last three centuries has brought men closer to a state of affairs in which absolutely nothing would be recognized in the whole world as possessing a claim to obedience except the authority of the State. The majority of people in Europe obey nothing else.”
—Simone Weil (1909–1943)
“The highest form of development is to govern one’s self.”
—Zerelda G. Wallace (1817–1901)
“The Cairo conference ... is about a complicated web of education and employment, consumption and poverty, development and health care. It is also about whether governments will follow where women have so clearly led them, toward safe, simple and reliable choices in family planning. While Cairo crackles with conflict, in the homes of the world the orthodoxies have been duly heard, and roundly ignored.”
—Anna Quindlen (b. 1952)
