The fact that the last ELL train leaves Canada Water heading south at 23.56 is definitely bad news. But there are also problems in the timings of late evening ELL services.

Here are the times of the last trains leaving Canada Water heading south: 22.26, 22,46, 22.56, 23.16, 23.26, 23.46, 23.56.

In other words, if you arrive at CW (or any other ELL station) at 22.26, 22.56 or 23.26 you will have to wait 20 minutes for the next train south. This isn't a "tube-style" service. Almost all LU lines are still operating an average 10tph service between 10pm and midnight.

We've been sold the idea that the ELL is a "turn up and go" service providing an alternative to using London Bridge in the late evenings. It isn't a "turn up and go" service if you have to potentially wait 20 minutes to catch an ELL train between 10.30pm and 11.30pm - precisely the period when people are returning from an evening in town.
