Peak time service on the Southminster Branch Line
(Based on timetable before 12/12/04 - i.e. this is not current)
An inspection of the timetable will show that trains can be run every 38 minutes. The 1816 and 1854 from London in the evening both depart 38 minutes apart. Yet even in the peak periods, trains from London's Liverpool St usually have intervals much in excess of this.
| Departure time from Liverpool St | Time since previous Southminster train |
| 1722 | 42 minutes |
| 1816 | 54 minutes |
| 1854 | 38 minutes |
Now these can be compared with the trains to Southend Victoria, over a similar time period.
| Departure time from Liverpool St | Time since previous Southend train |
| 1714 | 10 minutes |
| 1724 | 10 minutes |
| 1734 | 10 minutes |
| 1744 | 10 minutes |
| 1754 | 10 minutes |
| 1804 | 10 minutes |
| 1824 | 20 minutes |
| 1834 | 10 minutes |
| 1844 | 10 minutes |
