Some background: I made this site because over the years I've had a lot of experiences where the official Transport for London Tube (metro) statuses were wrong (e.g. ‘Good Service’ when there were delays or ‘Severe Delays’ when it wasn't that bad). I looked into it towards the end of last year and apparently TfL staff set them manually (using guidelines). It isn't really a 21st century way of doing things (it’s at least slow/inexact/inconsistent, and probably prone to truth bending etc.), so I ended up creating TrueTubeStatus.com. It monitors trains across the London Underground (using TfL’s API) and compares live performance with timetables to produce objective statuses. A few ways it can be useful: Peace of mind that an official ‘Good Service’ status is backed up by the maths. When it shows a delay that TfL isn’t reporting you can dodge it (delay your journey, change your route etc.) or at least brace yourself! You can see recent performance in a color-coded sparkline (mini chart without axes), which tells you how good/bad things are and where they’re headed. I’ve just put it in open beta and would be very interested to know what people think!
