That section is only for 110, so let it b EMD, ALCO or an ELECO, all have to stick to that.
ALCO's can touch 120-125 kph in SHF mode n in LHF, there is no specific restriction exceptional given by authorities. due to the view issues, the speed is lowered so that both the crew can communicate if there is a curve or a signal ahead.
Similar case goes to EMD too.
But...
more... the passenger version differs from the freight version locos.
