Swindon and the Cambrian Lines

There’s only time for a very quick blog post this week, as life is getting in the way. So, on with the show…

Two new maps this week:

  • The Cambrian Lines map is ready – although it looks easy, it took much longer than expected
  • The Didcot Parkway to Swindon map is up, covering from just west of Chippenham to Didcot Parkway, including an overlap with the Oxford map, which will be slightly redrawn and extended later

And finally, before I go to tackle the gardening – last week’s update introduced an unfortunate latency bug, meaning at peak times, the maps were lagging behind reality by as long as 30 minutes in some cases.

I’m really sorry that I didn’t spot the bug during testing – but I’m pleased to say it should now be fixed, and I’ll be keeping an eye on the maps this week. For the technically minded, this was caused by the train describer handling code searching all berths for a train description, rather than searching specific berths. The fix is simple – as with a SQL database, an additional index.

So, that’s it for this week – I realise I’m also behind on fixing some of the bugs on the site, which I hope to tackle this week. There won’t be any new maps next Sunday, as I’ll be busy preparing my presentation for OpenTech 2015

One thought on “Swindon and the Cambrian Lines

  1. Excellent – my home ground on a map!

    I assume the signal indications will not go live west of Challow until control moves to the TVSC at Didcot (and most of the signal numbers change!) ?
