Show HN: The Official National Train Map Sucked, So I Made My Own(www.bdzmap.com)
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!

Nice job! I took the train from Sofia to Plovdiv a few months ago, and this would have been a great resource to have.

(I wish someone would make a similar thing for Amtrak, which has a route/progress tracker that only marginally works IME.)

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!

In case you haven't stumbled upon it

I used it recently to find a land and sea route from Southampton to Marrakesh, along with Google maps faint representation of ferry lines, Google doesn't have public transit directions for the trains in Morocco shrug

no zoom buttons :(

Fair point! I relied entirely on scroll/pinch-to-zoom to keep the interface clean, but I should add standard +/- buttons for accessibility and desktop usability
