Later in the day I caught very rare foreign power on a BNSF train at Cajon siding:
In recent weeks, I've spotted a number of Tier 4 GE demo or lease units on Cajon Pass. GECX ET44AC 2043 is the blue unit on the lower track:
So far, I haven't seen one leading. However, I did catch a less distant shot of one, GECX 2030 on Sullivan's curve:
Notice, though, that ET44 GECX 2030 lacks the dip in the roofline in front of the radiator that's on the BNSF ET44 3912:
Great topic, great photos, great scenery! A very well done and informative series John. I checked out the "hump on the long hood" and found this information;
ReplyDeleteTier 4-compliant GEVO's feature much larger radiators with split cooling. Pre-production demonstrator GEVO's also feature a "hump" in the middle of the long hood, which houses a urea-injection exhaust after treatment system. No railroad has ordered the urea after treatment system, making the "hump" irrelevant on Tier 4 production models. The Tier 4 units have been unofficially named "ET" rather than "ES", the "T" stands for "Tier 4". This designation is currently only used by BNSF.
John, that's really good info, I wasn't aware of that.
