请帮我用英语简单描述图画，一两句就好（中心人物+动作）。谢啦

In the picture, six workers are divided into two groups to build one railroad separately from two ends. Unfortunately, the two parts fail to meet each other precisely or even roughly. This incident should be ascribed to the lack of team work, especially communication of two groups who are now quibbling loudly and think the other is the one to blame.
