On Sunday, 11-Feb-2007, Amtrak made a special trip down the Joint Line to deliver Amtrak HHP-8 658 (an 8000hp electric from the Northeast Corridor) and the FRA's new test car, DOTX 220, just released from Colorado Railcar. The pair are headed for Pueblo's AAR Transportation Test Center, where the new car will be certified for 120+ mph operation.
Power for the move down the Joint Line, since we don't have overhead electrification yet, was Amtrak P32-8BWH #518. Both locomotives came west on Sunday's California Zephyr. Based on what I heard from other fans today, there was a full Amtrak crew aboard, along a BNSF pilot and an HHP-8 qualified engineer straight from the NEC.
