couplings

the train had several loose couplings, causing delays.

we tightened the couplings to ensure a secure connection.

the couplings on the railway car were inspected for wear.

replacing the damaged couplings is a priority for maintenance.

the couplings linked the two railway cars together.

careful alignment is crucial when installing new couplings.

the couplings experienced significant stress during the journey.

standardized couplings ensure compatibility between railcars.

the couplings were made of high-strength steel.

regular lubrication of the couplings prevents seizing.

the couplings' design improved the train's efficiency.

we ordered new couplings to replace the old ones.
