>>1244802>Also very surprised to see a trolleypole on a full heavy rail unit.Was reasonably common on burgerland interurbans.
Trolleybuses are limited in speed to about 50 kph (30 mph) by the trolleypoles, but it's because they widely swerve away from the wires. Since rail vehicles don't swerve, the trolleypoles still allow up to ~150 kph (90 mph), although they need precise hanging especially on curves. See pic related.
Pacific Electric and North Shore line routinely went up to 125 kph (75 mph), likely even faster at times.
