The thing is will EMD build you new US domestic style locomotives that don't meet current Tier 4 emissions standards ?
Certain heavy haul railways here aren't interested in anything less than USD type units for obvious reasons . I really can't see locally built C44ACHi or GT46ACes turning up on red dust trains for mainline operations anyway . Too expensive too light and not enough fuel tank capacity .  
Buying a power assembly even in an export type locomotive is one thing but getting them in a full sized unit is another .

The point that I am trying to get across is that EMD export/license built production over the last few years, is higher than US domestic (prior to the skewed marketplace in 2014), in 2012/13 the number of DLW Varanasi produced GT46AC exceeded Muncie's domestic totals

The 710 will become an export prime mover. EMD's export market could not give a toss re US EPA standards. EMD tailors export engines to customer requirements, Do you think that the likes of Indian Railways will change spec to appease US greenies? The EPA only has the authority to dictate US domestic standards, they have no power to dictate on what is exported

EMD domestic locomotive production 2013 was just over 250 units, 2014 was an unusual year due to the pre Tier 4 rush, with around 500 units built, however the bulk of these were subcontracted to Bombardier in Mexico

It will be a few months before the final 2014 figure is confirmed (due to uncompleted units being delivered ahead of the Tier 4 cut-off, and stacked at customers premises to be finished Q1 2015)

There will be little EMD domestic production 2015 and 2016. EMD will be heavily dependent on Muncie built export locos and CKD kits, 710 engine exports, and license fees, until their Tier 4 engine family is certified by the EPA (possibly Q1 2017)

Why wouldn't EMD build them?

GE built quite a few Rio Dash 9s after the advent of T2 in the USA.
The compliance decal just said "not for use in the USA or Canada".

EMD could do exactly the same thing. It isn't as if they sold the rights to the drawings to someone else.

There was an interesting post on the Trains website tonight.
Vossloh have sold some Euro 4000s to to a French customer for 2015 delivery, so they must meet Euro IIIB which is more or less equivalent to USA Tier IV. I assume they will use SCR and urea as they are already doing with 2015 delivery Eurolights.

So the 710 can be used in areas with restrictive emissions control.
It is only in the USA and Canada they want to avoid the use of urea.

With EMD's domestic production in North America on hold for the next two years as they work towards production of a new domestic Tier 4 primemover, my thinking is they'll be bending over backwards to make anything for export with a 710 - they need the business and have been building up the Muncie-built export trade over the last couple of years.

There has been discussion re the Vossloh sale to France on a couple of European groups

The Euro regulations apparently contain a loophole

An operator (or builder/assembler) is allowed to acquire/build/assemble non complaint locos post implementation of the new standard, for use within the Euro Zone, provided that the engine was purchased, and shipped into the Euro Zone prior to 01/01/2015.
Vossloh has apparently stockpiled a number of 710. Some operators have also been stockpiling engines. GBRf in the UK recently  purchased 5 new, and holds 2 zero hour rebuilds, so is expected to purchase an additional seven 66 Class this year, then fit their own engines then the locos arrive

Plus this comment sums up the French "There is also the possibility that the French will simply ignore (or re-interpret) the regulations. French culture definitely has rules that you must obey & rules that you can ignore. The foreigners are screwed if they get confused and ignore any of the ones you must obey and drown in bureaucracy if they follow rules the French ignore".

Thanks for your political and cultural insights jmt, would be lost without it.

710s have been export engines for ages , possibly first appeared here in DLs ANs and from memory that GML10 .
And so it goes 82s 90s Qs 4000s GT46ACes .

Toad Montgomery has posted that the Roy Hill ES44ACi locos have 'started' to arrive.
