Just to follow up on the last post about the launch of the “Night Tube”, the service launched on the Jubilee Line last Friday. There are now close to 40 tubes running over night at the weekend on the Central, Victoria and Jubilee lines. The chart above shows the number of tubes running on Thursday 6th October through to 23:57 on Sunday night. The morning and evening peak rush hours are evident for Thursday and Friday, then the first Jubilee Line night services can be seen in the trough between Friday and Saturday.

The interesting thing to do now would be to run a public transport accessibility analysis using the real-time running data to see which parts of the city are now more connected. As today is the second day of the Southern Rail strike, that might make another interesting subject. Using the Census travel to work data we could forecast the areas where people are going to be late for work because of transport failures. That could potentially give a measure of what effect any strikes, or even just “congestion” generally, is having on London.

On a technical level, one thing which is now becoming apparent is that the number of drop-outs from the API has increased. It used to be that there would be a few per day on the Northern Line (biggest data), but now they seem to be occurring randomly across all the lines. The CASA API has been collecting data since the London Olympics in 2012, so it’s long overdue for some maintenance.
