Can a gear train change speed?
Can a gear train change speed? In this gear train, the driver wheel gear has 24 teeth, while the driven wheel gear has 16. Since the driven wheel gear has fewer teeth, it rotates faster than the driver wheel gear. This results in a speed increase.
How do trains increase speed?
The faster speeds are achieved through various means including new rolling stock such as tilting trains, upgrades to tracks including shallower curves, electrification, in-cab signalling, and less frequent halts/stops.
