I want to know the answer to the following question:
What type of locomotive technology was to be developed by GE under its Ecoimagination program?
All the background I'm provided with is that "In May 2005, GE announced the launch of a program called "Ecomagination," intended, in the words of CEO Jeff Immelt "to develop tomorrow's solutions such as solar energy, hybrid locomotives, fuel cells, lower-emission aircraft engines, lighter and stronger durable materials, efficient lighting, and water purification technology".". Is that enough to answer the question?
Answer: yes
