Right now it works fine, at 02:00 am however, there JSON structure retrieved from api.irail.be is different. See for example: http://api.irail.be/liveboard/?format=json&lang=NL&station=turnhout&fast=true&time=02:00. We should be able to handle this as well.

Solution

Handle when the liveboard is empty and give an appropriate message in the view

Alright. I will try to work on something for this.

@pietercolpaert This also affects the TravisCI testing part on the PR's

@Tjoosten any news on this? There seem to be a couple of issues that you assigned yourself to but we have not heard anything about it any more. Please also indicate if you want someone else to fix this issue, otherwise it's going to be open for a lot of more time.

@pietercolpaert I can give u a update later this day. Currently I'm on my work. And I have not the tools to dig into this.
