Development
Initial plans for a large fleet of Mk3 loco-hauled coaches to run on almost all Inter-City services were amended prior to construction to provide stock got the planned InterCity 125 fleets, resulting in a much smaller fleet of loco-hauled coaches for West Coast Main Line (WCML) services.

Famous quotes containing the word development:
“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 child’s problems.”
—Lawrence Kutner (20th century)
“The proper aim of education is to promote significant learning. Significant learning entails development. Development means successively asking broader and deeper questions of the relationship between oneself and the world. This is as true for first graders as graduate students, for fledging artists as graying accountants.”
—Laurent A. Daloz (20th century)
“Other nations have tried to check ... the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions.”
—John Louis O’Sullivan (1813–1895)
