Tehachapi_(1992) SP Oil Cans With Twelve Units 

The BN Unit was probably a run-through, or possibly a leaser, and the other one was simply an SP locomotive that happened to be in the yard when they were assembling the helper lashup. SP had a tendency of throwing whatever was available onto trains as helpers, it wasn't uncommon to see SD9s and SW1500s occasionally helping with a grade, so the fact they put a B40-8 on there doesn't surprise me.

Those "pipes" were hoses that allowed to load the entire train from a single point, instead from each car individually.

@@ortlu-ro9yndamn that means these cares a fully fully loader. Heavy shit yo

That's........ wildly incorrect.

Each car weighs 263,000 pounds loaded. They ran in 66-72 car sets. MTY weight was 78,300 pounds. So that's false. And now onto the locomotives: SP SD40T-2 8241- EMD V16-645E3 3,000HP SP SD45R 7448- EMD V20-645E3 3,400HP BN 5509 C30-7- GE 7FDL16 3,000HP SP 6808 SD45T-2R- EMD V20-645E3B 3,400HP SP 7409 SD45R- EMD V20-645E3 3,200HP SP 8293 SD40T-2 V16-645E3 3,000HP SWING HELPERS: SP 6825 SD45T-2R- V20-645E3B, 3,400HP SP 7560 SD45R- EMD V20-645E3, 3,200HP SP 7405 SD45R- EMD V20-645E3, 3,200HP SP 8011 B39-8- GE 7FDL16, 3,3900HP SP 7481 SD45R- EMD V20-645E3, 3,400HP SSW 9655 GP60- EMD V16-710G3A, 3,800HP
