What HN said

Smooth animation and Mini Metro feel
From 3 comments
Very nice. Given the smoothness, I first thought this was real-time:) As someone who lives in Berlin, I didn't know there was an open API for the VBB. I'll have to have a look at…
radiosnob on HNAgreed on the minimetro feel! I thought it was live too, I wonder if there's a way to do that? I like that you can see both the s and u bahn, though I kind of wish the abstract…
YLE118 on HNMini Metro IRL. Kudos!

Clever fade in/out handling of terminal trains
From 1 comment
The solution with fade out / fade in is pretty clever. Short layovers will cross-fade automatically, but you don’t need complicated internal information about which train…

Objections
Very slow rendering in Firefox
From 4 comments
It's super smooth on Chrome, but it's doing (say) 1 frame per second on Firefox.
akie on HNExtremely slow for some reason in Firefox on Mac OS for me
Quanttek on HNTotally unusable in Firefox on Windows 10 as well.
runxel on HNSame here. A profile suggests that most native time is spent rendering the backdrop shadow of the text rendered to the canvas, and most of the remaining CPU time is spent on the…

Trains do not stop at stations and disappear at terminals
From 1 comment
Nice! Would be more realistic (and more Mini Metro-like) if the trains actually stopped at the stations though. Also, the trains don't have to disappear and reappear at the…

Map is schedule-based, not real-time
From 2 comments
What's the purpose of animation here? It seems to have no information about actual train position, or am I missing something?
divan on HNI think it is just a toy :) But the trains are sort-of-actual positions based on the time in the top right hand corner and the latest estimated arrival times, but time is moving…

Does not combine S-Bahn and U-Bahn well
From 2 comments
The problem with Berlin is than there are many operators for public transport by train: * U-Bahn, for the subways (underground & aerial) * S-Bahn, for sub-urban lines (mostly…
miniwark on HNThere's actually a button in the upper right corner to enable both S+U Bahn! Although the app gets a little sluggish for me when I enable them both.

Add live real-time mode
From 2 comments
Agreed on the minimetro feel! I thought it was live too, I wonder if there's a way to do that? I like that you can see both the s and u bahn, though I kind of wish the abstract…
YLE118 on HNThanks a lot for the feedback!! The "live mode" is already developed using hafas-client[1] and VBB-API[2]. I just asked VBB to give me API access, I'll release the feature when I…

Show engineering works and temporary route changes
From 2 comments
I really like it! Well done! - As others have mentioned, it seems dodgy on Firefox. The button to switch between U-Bahn and S+U mode doesn't seem to work at all on Safari (?) -…
NeoTar on HNNice, only thing is it's not currently accurate. The U1 and U2 have temporarily combined into the U12.

There is a real Berlin live map of subway, bus and railway at: https://www.vbb.de/fahrinfo/ by the operator. Seems no english version available, you have to ``` - click upper…
