BaltACDI do believe GE beat Cummins to Tier 4 certification and have been turning out T4 compliant locomotives since the end of 2015. So the puffery of being 1st to be T4 compliant is false.
There are a number of these 'reports', all suspiciously worded alike and, I suspect, taken from a Cummins press release with a little too much editing. Either 'prime power' is a codeword for something to do with smaller engine footprint or weight, or the qualifying words 'high-speed' were removed from the blurb about 'first' engine qualifying for Tier 4 certification. (Didn't MTU have a fairly large engine that passed Tier 4 without aftertreatment a relatively long time ago, and hasn't the C175-20 variant, at least the genset version, passed with urea?)
Didn't we discuss this back in April and determine that GE Had the entire Locomotive certified, not the Prime Mover without the locomotive built around it? Whereas, since Cummins doesn't build locomotives, only Diesel engines, they Certed the engine independent of installation. So they were both first in their respective categories. IT is of course mincing for purposes of marketing.
If Cummins holds up to its name of being one of the most reliable and efficient motor making companies, we might see some new locomotives with Cummins power. Again, that depends on if they get a working formula with this new engine.
