FILE – In this Feb. 28, 2008 file photo, rail cars arrive in Milton, N.D., loaded with pipe for the first Keystone Pipeline project, which now carries crude oil across Saskatchewan and Manitoba, and through North Dakota, South Dakota, Nebraska, Kansas, Missouri and Illinois. TransCanada’s second pipeline, the $7 billion Keystone XL, designed to carry crude oil from tar sands near Hardisty, Alberta to the Gulf Coast is now delayed indefinitely, with little official explanation. The company had hoped to begin laying pipe by the end of the year, but those prospects have dimmed. (AP Photo/Grand Forks Herald, Eric Hylden) NO SALES
