Q. I am finding an article about rail way trolley and how human power may be used to power the various components of the trolley?
It looks like you can find information about this via Engineering Village. Go to the Mechanical Engineering Database page (http://www.pi.ac.ae/library/subject/me.php) and click on the Engineering Village link. Try searching for "Human Powered Transportation". You can also try the other databases on that page as well.
