I know that back before the Moffet Tunnel opened on the California Zephyr route there were some 4% grades over the Continental Divide.
It seems the south track over Cajon Pass the Southwest Chief uses is a 3% grade, or has sections that are 3%.
It's kind of surprising but there don't seem to be any loops to/from Cajon Pass.
Are the any steeper grades?
Loops on grades I've found:
California Zephyr
Big Ten Curve
Gilluly Loops
Arnold's Loop
Emigrant Canyon/Donner Lake Loops.
Empire Builder
Iron Ridge/Greenhorn Creek/Austin Road loops
Baird Springs Road loop
Foss River loop
Index loop
Coast Starlight
Chorro loop
Rollercoaster Trail loop
Tehachapi Loop (only when the regular CS route is unavailable)
Cantara loop
Sawmill Curve
Shady Gap loop
Flat Creek loop
