Yes, however there are two primary causes of squealing wheels.

1) Flanging
2) Wheel Creep

Most squealing is caused by Wheel Creep, as one wheel is not turning at track
speed, and cannot be illiminated without lubricating the rail head.  Tests are
currently underway in the Beecroft area to test rail head lubricators.
