Where is it's sister unit, the 1609 at ? These 2, EMDX 1608-1609 spent a few weeks in Pueblo Co after being pulled from the TTC/MxV Rail Facility back in April. New info on the performance of these 2 perhaps? To send them back here, well must be something. Ben

Appreciate your photo posting of EMDX #1608.

Just spotted 1609 at Progress Rail's McCook (LaGrange), IL facility yesterday,

Nice!  Sure wish more of these had been ordered.

They're prototype test units, doesn't make any sense to build more until have these have been tested and the bugs worked out.

UP has a hundred of them... NS and CSX also had 10 each. Whatever is being tested in 1608 and 1609 is something additional to initial type testing.

The 1608 lingered in Roseville for about 3 weeks in June. Today is has made it to Pueblo.

UP has 87, never reached 100 -- ask them why they cancelled part of the order. NS cancelled their 10, which became part of the Progress lease fleet. CSX returned theirs to EMD.
Progress has had a continuous mod program for their Tier 4s. Sometimes a mod will go into their test or lease fleet to see how things work out. Sometimes a mod will go straight into the UP fleet.

I'm not sure if it was 100 or 87 for UP, but either way it shows there were quite a few production units delivered after the 15 or so prototype units had been tested.
