But first, a new diesel-electric locomotive from General Electric, the "6662". This one is 3 weeks old. I some how lost the data sheet for this locomotive so the information I have added to the pictures is from Wikipedia.
The ES44C4 is the newest 4400 HP model in the Evolution Series. It is similar to the ES44AC, except that it has four traction motors instead of six. The center axle of each truck is unpowered, giving an A1A-A1A wheel arrangement. BNSF is the launch customer for this model, ordering 25 units numbered 6600-6624.
A unique feature of these units is that there is a variable traction control system in their computer systems. One of the differences between an ES44AC and an ES44C4 are the air cylinders and linkages on the truck sideframes of the ES44C4; these are part of the traction control system.
The Evolution Series locomotives are visually similar to the Dash 9 and AC4400CW, although small differences are evident. The most significant differences are in the radiator section at the rear of the locomotive; the "wings" at the end of the carbody are larger, as is the entire radiator of the locomotive.
As with the AC6000CW the radiators project beyond the end of the hood, and unlike any previous GE locomotive the grills under the radiator are at two different angles. The increase in radiator size is due to the necessity of greater cooling capacity in the locomotive in order to reduce emissions.
Here is a LINK to the Viewliner Limited Blog for another great locomotive from the past that was also at this event. ENJOY!
