Motor design and manufacturing being two very very different things.thanks for that lot
"motors in Hennigsdorf" is the key text for my comment about the legacy of Mitrac motors - Hennigsdorf being ex AEG, which is where I thought they descend from, and the production point of view.
Most Adtranz / Bombardier motor designs were ex BBC Zurich design heritage and originally usually Vienna (now TSA factory) manufactured, with some ASEA Vasteras design heritage and some AEG design heritage. Most of the manufacturing was switched to the ex AEG / ex LEW factory for cost and political reasons early in the Adtranz era. I think all of the ex AEG heritage motor designs have been phased out of new production in the last ~5 years due to competition (mostly Siemens) forcing higher performance requirements.
