Some days I wish the knowledgeable people in these threads would become Wikipedia contributors. Their pages are only as good as the contributors. An engineering document with a copyright date would be a valid source to update the article. Not calling anyone out per se' I don't need another hobby either. :( but the info is out there, just not in the hands of the Wiki contributors.

The problem with contributing to Wiki with such data is that someone will come right behind you and revise the entry citing one of the "mass market" books that are full of errors as the authoritive document.

That's what the talk page is for. The article for the EMD 710 has nothing on the talk page. Nobody has challenged any of it.

The Topic Title on this Thread threw me for a curve....Does the OP refer to the units by their 'paint scheme' name ?  The green and creme painted units in the classes mentioned in this Thread are often referred to as "Grinstein Green" to pay homage to the then president of the railroad Gerald Grinsterin from 1985/95 and over saw the purchase of the SD70 (varients) 

One of the first casualties of the BN>BNSF mergers were the 'Executive Train' power units BN1 (A)/Bn2(B)/BN3 (A).  In 1997 they were donated to the IRM museum's fleet.  They had just beren reworked for their roles as Executive Train power, and were a matched set of matched E-9 units. Their paint scheme was slightly darker than the Grinstein(Pulman) Green, and had a red line for the color separation. { They had also been fitted with diaphragms between the units, and extended couplings to allow for that new hardware.}    Ok, consider my 'nits' picked! Bang Head

I take issue with your nits, Grinstein Green is the color green used. The paint scheme is called the Executive Scheme(or colloquially, Cream and Green), because it was put on BN1,2 and 3 FIRST! The executive units got the executive paint scheme. Also, the SD70MACs in fact ALSO have a red stripe and the shade of green is the same.To my knowledge, neither is considered Pullman Green. Finally, the 3 executive units are NOT a matched set. BN1&2 are former NP F9s that were completely rebuilt with 2000HP 16-645E Prime movers. In a sense, they are F38-2s. BN-3 was a (I assume CB&Q) E unit that had been in Chicago commuter service. It is unmodified. So, to reiterate, the OP is correct, that paint scheme is called the BN Executive Scheme. Grinstein green refers to the shade of green.

  To YoHo 1975  Bow  I owe you a mea culpa..Sigh  I guess my eyesight is not what it used to be as to color definition.. We get the occasional Grinstein Green scheme on units passing through this area [mostly, on coal trains/ empty returns, via KC area?]. 

 I remember reading in an old edition of TRAINS about the donation of the BN Executive Train power (A-B-A) set to the IRM. I think it was about 1997(?). Somehow it 'stuck' in my memory that they were a 'matched set' from that article(?).  I seem to recall that when they were donated, they they had just been outshopped, and were virtually rebuilt to (then) updated specifications, you had mentioned.        One of the mods mentioned were the application of full height passenger-style(?) diaphragms between the units.. Odd, but it had increased the need to lengthen the couplers between the units to accomodate that adition.    Appreciate, your addition to the info on the three units.Thumbs Up

I know for a fact the F units were donated in 1997. I've heard that the E-unit came later, but whether that means a few months later or a year later or? I don't know.
