The ES44C4 (Evolution Series, 4400 HP, C to denote 3 axles per truck, 4 traction motors) was introduced in 2009. While similar to the ES44AC, the ES44C4 has two traction motors per truck, instead of the conventional three such as on the ES44AC. No ES44C4s with DC traction were built. The center axle of each truck is unpowered, giving an A1A-A1A wheel arrangement. BNSF Railway is the launch customer for this model, ordering an initial batch of 25 units numbered 6600-6624.[7] As of 2020, BNSF Railway currently rosters over 1200 ES44C4 units The ET44AC (Evolution Series Tier 4, 4400 HP, AC traction) replaces the ES44AC model. These locomotives have been ordered by most of the Class I railroads in North America, including Union Pacific, CSX Transportation, Norfolk Southern and Canadian National Railway. BNSF Railway will be receiving similar ET44C4 locomotives, which have no traction motor on the middle axle of each truck. CSX designates their ET44ACs as ET44AH, due to their locomotives being Heavy-ballasted.
Do we really need more BNSF content? We have around 15 different pieces of BNSF DLC for the game, either it be locomotives or routes. Plus with how BNSF licensing rules are, there are problems with international releases (removing logos). If you want ET44s, Ian (eyein12) has a pack including BNSF variants for sale on his site.
I don't think DTG will bother, since it can't be sold outside of the USA. Maybe a 3rd party developer could make one.
The OP will be happy to know that there is a BNSF ES44DC in the game. It released October 17, 2013. The OP will be unhappy to learn that, unless he's American, he cannot buy it. So I agree that we should not focus on BNSF. Period. Unless it is going to be unbranded in all instances. And DTG typically doesn't do that. Though I'm trying to build a case for unbranding Marias Pass and adding some unbranded locos to it as a special project (in addition to a different branded livery that American players can buy separately). We shall see. Meanwhile, may I suggest Travel By Train? That CN SD60 for $19.99 (US) on Steam is $9.95 on their site. They also sell the BN GP50 in Tiger livery, an ATSF GP40X, and a BN bundle with another GP50 and a GP35. That last one, in The Complete set (note, GP35 not included in that) features the GE C30-7 and GE C33-7 as well as the B30-7A and 7AB booster. Oh, and last one, the Atchison, Topeka and Santa Fe model of the GP35. Those may tide you over for your BNSF wishes. They also seem to have released a new item since my last visit, which appears to be a CP SD60, featuring scenarios for Canadian Mountain Passes (which I own, so I'm holding out for a sale myself, but likely getting it)..
