Common fault types and phenomena in railway point machines.

Type	Fault phenomena	Sample size
F1	During the unlocking, the current value experiences continuous fluctuations before reaching its peak.	90
F2	Around the 1.8 s, the current value undergoes a rapid decline, plummeting from 2 A to 0.	90
F3	The current continues to output, failing to decrease to its normal level at the conclusion of the locking.	90
F4	After entering the slow release stage of 1DQJ, the current exhibits anomalies and subsequently vanishes.	90
F5	During the deceleration process, the current of 1DQJ significantly exceeds 0.5 A and consistently hovers between 0.7 A and 0.8 A.	90
F6	The duration of slowing for 1DQJ extends beyond the typical time range.	90
