Show HN: The Official National Train Map Sucked, So I Made My Own

Hi HN,

I’m a junior developer. I wanted to share a side project I’ve been working on.

The national railway carrier (BDZ) has no public API. They have an official map but the UI is quite dated, often lags, and doesn't show the full route context.

I wrote a short write-up about the process here: https://www.pavlinbg.com/posts/bg-train-tracker

I know it's still rough around the edges (I'm still working on it), but I’d love to hear your feedback or suggestions!

BDZ is Balgarski Darzhavni Zheleznitsi, Bulgaria's national railway.

Thank you; would be nice if the country would be clear from the post title

Thanks. I wish we had a map with freight trains too. I have always been a railroad fan and my favourite trains are those long freight trains. I also love watching the operations of marshalling stations too!
