英语翻译
在高峰小时,列车采取从车场尾部折返线转线立折的方式.因为发车作业时间7分钟,在紧凑发车（间隔3分钟）情况下必须占用4条到发线,因此,将上半场4股到发线用于发车,下半场3股到发线用于接车（由于终到作业时间6分钟,仅三股到发线也不能连续接入3分钟间隔到达的列车）.
在非高峰小时,列车采取本线立折的方式.7股到发线均可进行接发列车作业.
在列车接续方面,由于从列车始发,至再次从终到站发车,至少需要45分10秒（下行方向）/44分15秒（上行方向）,因此,仅靠到达列车接续（天津站）,高峰小时最多能够发车15列；而为了满足早高峰发车需求,天津站夜间至少需存车10列以上.
在发车时间方面,由于高峰小时接发15对列车（因为存在中间站停站列车）,终到站到发线能力非常紧张,因此,在列车发车时间点上没有规律,无法建立规格化运行图.

Answer 1

At peak hours,to take the train from the rear yard line to turn back legislation to line break.Start time because of work 7 minutes,start in the compact (3 minute interval) cases must be made to take up 4 lines,will be made to Unit 4 in the first half for the start line,the second half 3 shares issued to the line for vehicle access (As the final 6 minutes of time to work,only three lines can not be made to access 3 minutes interval in a row to reach the train).
In the off-peak hours,the train line to take this break legislation.7 shares issued to the line can be carried out next train operations.
In the next train,the train originating from,to start again from the arrival terminal,at least 45 minutes 10 seconds (downlink direction) / 44 minutes 15 seconds (uplink direction),only reached the next train (Tianjin Station) ,The peak hours up to be able to start 15; as early summit and to meet the needs of start,Tianjin night stand at least 10 more parking.
At departure time,since the peak hours then made 15 pairs of trains (because of the train station stop in the middle),end-to-fat line of departure and arrival capacity is tight,so the train departure point in time there is no law that can not be established standardized plans to run .
