In May, an east-bound train derailed in Bridgeport, Connecticut and was hit by a westbound train.

今年5月, 康涅狄格州布里奇波特的一辆火车脱轨和西行的列车相撞。

Unbidden by the westbound winds, warm water in the western Pacific sloshes back toward the Americas.

西太平洋的暖水不受西行风的影响，回流到美洲。

Usually, the median has either grass or cement that separates the two sides, so the eastbound and the westbound.

通常， 中间带有草地或水泥将两侧分开，即东行和西行。
