The railroad that I work for has the GE tier 4 ES44AC locomotives running freight now, most of them coming out of the new texas plant.

Plus, some of of the older ES44AC’s in our fleet are being refitted with the tier 4 EVO common rail FI engines.

As an aside, the transition from Erie, PA. to Texas seems to have caused some build reliability issues. We’ve been keeping the local GE service rep busy lately with warranty claims.

Well, the design is so new that there's bound to be reliability issues. In fact, EMD is still experimenting around with Tier 4 locomotives designs--the last I heard was using a redesigned 12-cylinder version of the 265H engine.
