Long Sin hurried down the road until he came to a trolley pole, then looked hastily at his watch.

From nearly every window and balcony hung pennants and flags; on every trolley pole fluttered a pennant of red, white and black.

The trolley wheel is supported by a trolley pole, and is maintained in good electric contact with the trolley wire, or overhead conductor.

It's at the end of the long pole (the trolley pole) that reaches from the roof of the streetcar to the overhead line.

A lot of old trolley poles were sold to China for irrigation wells.
