GENESIS has proven iteself before the EMD DE/DM was even thought of.

True, but it depends on what you accept as proof.

For example, the MDBF on MNR's Genesis locomotives that's been recently reported was:

July 2007 -- 35K miles
12-month average as of July 2007 -- 27k miles

So it's reasonable to think that LIRR was aiming to exceed the performance of the Genesis locomotives, which on an absolute scale don't seem so reliable, although they're something like twice as reliable by these measures as LIRR's DE/DM30s. So I think something like that was the motivation for LIRR. By contrast LIRR has been reporting MDBFs lately for its M7s of between 250-300k miles.

Even in retrospect, I can't say that LIRR's motivation was misplaced, although obviously lemons were produced. But I don't fault LIRR for aiming higher, only for failing to execute, and for even failing to meet the goal they were trying to exceed.
