Show HN: Truetubestatus.com – Better service statuses for the London Tube

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!

Some feedback: I would expect this page to work really well on mobile because that's the kind of information you need on the go. However, on mobile everything just get's squeezed. The left side color bar takes as much space as the information it contains. On mobile you could really stretch the information on the right to take the whole width of the screen, and just keep the color bar on the top (toggle).

I am also concerned that my browser is caching the results. I accessed this page on desktop and it showed everything normal, then I accessed it on my phone and Jubilee was delayed. I had to "hard refresh" on desktop to get the update.
