Record 1 2024-07-04

English

Subject field(s)
  • Keyboard Instruments
CONT

Old upright pianos tend to develop all sorts of strange clunks, clicks, and buzzes. One cause of these noises is worn hammer rail felt. Over time, this felt becomes compacted and no longer provides adequate cushion for the hammer shanks. The compacted felt gives a dull thud when the shanks return to rest.

Record 4 2019-02-28

English

Subject field(s)
  • Railroad Maintenance
  • Tracks and Roadways (Rail Transport)
CONT

Rail wear results in an increase in stresses and reduces rail fatigue life. Consequently, worn rail will become more susceptible to development and spread of cracks leading to rail breaks, thereby increasing the risk of derailment.

French

Domaine(s)
  • Entretien (Équipement ferroviaire)
  • Voies ferrées
CONT

L'usure des rails engendre une augmentation des contraintes et réduit la durée de la résistance à la fatigue du rail. Par conséquent, un rail usé devient plus susceptible au développement et à la propagation de fissures qui donnent lieu à des ruptures de rail, ce qui augmente le risque de déraillement.

English

Subject field(s)
  • General Mechanics (Physics)
  • Railroad Safety
  • Rolling and Suspension Components (Railroad)
CONT

Truck hunting is wheel set oscillation caused by the dynamic response of a railway car truck when operating above certain speeds. The truck oscillates between the rails with hard flange contact occurring at regular intervals of 30 to 50 feet. Truck hunting occurs on tangent track and is more severe where the track is stiff and where CWR [continuous welded rail] is laid. It normally does not begin until around 45 to 50 mph in the case of cars with worn wheels, and 55 to 60 mph for cars with new wheels.

OBS

FIST A rail designed to prevent a worn wheel tread from striking the head of a running rail of a frog or crossing. The easer rail is so machined that its head, fits against the outside of the head of the running rail and is so bent as to gradually lift a worn wheel thread to the elevation of the top of the running rail so that it may pass over this rail.(MOWA 21, 129).
