| BNSF 6834 and 7222, on the point of a westbound stack train, race another west to Barstow. 6834 was built by GE as an ES44C4, similar in almost every way to an ES44AC, but with A1A trucks instead of the standard 6-axle trucks. 7222 was built in 2009 as a stock ES44DC. The third unit, 8000, is another ES44C4. |
