GE was able to make a locomotive that met the Tier 4 deadline. EMD is making a Tier 4 locomotive, but I recently read that UP is putting most of the 100 units it bought into storage because of electrical problems.
GE Transportation was recently merged with Wabtec in a $11.1 billion deal. Wabtec is the current name for the Westinghouse operation that invented air brakes. They have expanded into other railroad technologies such as PTC (Positive Train Control) equipment.

(new window) I can't believe they didn't hand the "bubbly gal" a torque wrench to finish installing the the "oh wow" oil pressure sensor. Letting the public think that finger tight is OK hurts my brain. I really miss the WWII produced videos that had a professional narrator behind the scenes focused on providing information. (I still haven't figured out if one guy did many films back in the 1940s, or if several guys did "the narrator voice." Some of the GE videos also had Adam Savage of Mythbusters fame. So they are not sexist. Sometimes they include a "bubbly guy.")
