EMD's SD70ACe-T4 is definitely boxier than its predecessor. Many people believe that EMD and GE designs are slowly converging and that it is becoming more and more difficult to tell them apart. However, this is still clearly very close to an SD70ACe. The long hood is a little taller (and more square) in front of the radiator housing. While it is difficult to tell from the ground, the SD70ACe-T4 has three radiator fans whereas the SD70ACe only has two.

A lot has changed in this view in the last ten years. The Sheridan Blvd overpass, which the train is running beneath, was completely rebuilt. That was done to provide enough room for commuter rail to fit underneath the bridge, which is on the opposite side of this coal empty. There are now two main tracks here for UP, the second completed just a few years ago. One thing that isn't new is the stub track in the foreground! It connects in with BNSF's Golden Sub and hasn't been used in a few years.

One of few-remaining coal trains on the Moffat heads west on Main 1 alongside the new commuter rail station near Sheridan Blvd. The train is headed for the Energy Mine on the Craig Branch. Upon returning east, the coal will be delivered to the Xcel Energy Cherokee power plant in northeast Denver. The plant is in the process of converting to natural gas and, by the end of 2016, this coal train will likely be eliminated. The closest track in the foreground is BNSF's Golden Sub. The track next to it is UP's Arvada Siding.

For decades, EMD has used either SD## or GP## as the prefix for its models. It seems that EMD is reluctant to go to a three-digit number (e.g. SD100), so all their new units in the last 15 years (basically since the SD90) have been "SD70ACe" followed by a suffix. That continues with the latest unit, designated an SD70ACe-T4. As you probably guess, the "T4" stands for "Tier 4", and indicates the unit is EPA Tier-4 compliant.

Introducting the SD70ACe-T4. This is one of four prototypes for the first EPA Tier-4 compliant engine produced by EMD. While it looks essentially like an SD70ACe externally, internally it is an entirely different animal. A few things to note externally. First, EMD is bringing back the teardrop windshield. A welcome change for both crews and railfans alike. Next, note the new fabricated trucks. Last, the long hood is higher and "boxier" ahead of the radiator housing. Internally, the prime mover is brand new. Traditionally, EMD prime movers have been two-stroke and 16 cylinders. This new prime mover is four-stroke and 12 cylinders. It still generates the 4400 HP the SD70ACe generated. On top of it all, the demonstrator paint scheme looks darn nice, too!

EMD is a little behind the curve in the "Tier 4" game. Starting January 1, 2015, railroads could only purchase engines that were EPA Tier-4 compliant. GE had production units rolling by late 2015. EMD had yet to roll out a prototype at that point. However, they now have four prototypes on the rails, two of which had been testing at the Transportation Technology Center east of Pueblo. BNSF brought them to Denver and, rumor has it they will head west on the Moffat next for some high altitude testing.

Always good to catch a Warbonnet, although sad to see this particular Warbonnet on this train. BNSF 521 has been working on locals in the Denver area for well over a year. I've seen it on the Beer Run as well as on the Longmont Switch. Time to say farewell for now as it departs for Lincoln, NE. Perhaps, with a little luck, it'll find its way back to Denver.
