Now that we’ve established the HEP source :wink:

Can the crew select which axle is unpowered, does the computer pick, or is it always the same one?

Generally the computer selects a pre-programed order. of which ones to Idle first.

The locomotive might change this depending if inverters fault out. But heck, an SD70MAC with four traction motors would still probably out pull the rest of the fleet.

I am looking at what EMD (PRLX/EMDX) has "sitting on the lot"

20 pre-production SD70ACe ex CSX.
14 first gen SD70MAC ex BN
50 to 60 SD70M/SD75/SD75I from CSX and BNSF

I might guess that they might be rebuilding the BN units... but where will the 15th come from
