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:
“To be sure, we have inherited abilities, but our development we owe to thousands of influences coming from the world around us from which we appropriate what we can and what is suitable to us.”
—Johann Wolfgang Von Goethe (17491832)
“For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.”
—Kyle D. Pruett (20th century)
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no right way, just as there are no magic incantations that will always painlessly resolve a childs problems.”
—Lawrence Kutner (20th century)
