上海地铁昨日表示，上海和江苏昆山之间马上即可实现地铁互通，列车即将开始试跑。

上海地铁表示，下一步，运营方将调试夜间行车的信号系统;通车后列车单程行驶这3站约需10分钟左右。

　　【讲解】

文中的trial run即为“试跑”。trial和run在此都是名词，trial意为“试验”、“试用”，常见词组又如：a trial period “试用期”，也可以表达为a probation period;on trial “试用中”，也可以表达为on probation。

另外，文中的test and adjust意为“调试”;one-way ride解释为“单程行驶”，类似的表达法还如：one-way ticket “单程票”;one-way street “单行道”。
