Need real time updates on train traffic and network
I need to obtain real time (or near real time) updates on the Tunnelbana and commuter (Pendeltag) rail traffic. Details such as train positions, delays, time arrived at station, position of train and so on. I was wondering if this real time information is available, (through one API call) and which API to use for that.
I have gone through the various APIs, and could not find any API which would provide real time information. I could find mostly schedule information. Could you please help me out?
