@caralara@chaos.social sorry to hear! Getting these accurate all the time is still a work in progress 👩🔧
🔥 If you're travelling by train this summer, you might want to check how disrupted trains can get in your area on hot days.
Read our report: https://chuuchuu.com/heatwave
Fediverse: we’re need of train nerd opinions! We’re planning to add statistics about your trips to the app. What kind of statistics would you like to see?
Some ideas we have: total time in trains, total time lost in delays, most visited station, how often you’ve been on the same train, … what would be cool to see?
Import from DB is here 🥳
In DB Navigator, choose Share Trip, then chuuchuu, et voilà: your train tracked in our app.
Alternatively, paste your journeys directly. Now on the latest TestFlight version!
Ok we got it - many of you wanted to find routes via a specific station. So we added it!
Now, what's your favourite via hack?
💺New: add your seats, know where to board!
Many of you asked for this. Add seat reservations for all passengers and see them on the live activity - no more triple checking your ticket!
We’re also adding train compositions. If you have a seat reservation, the app highlights where to board your train.
Now in early access on TestFlight, waiting for your feedback!
Little gimmick: we show the trainset number of ICE trains. Who among you tracks how often they’ve been on the same train?
Maps are coming?? 🗺️
Keeping you train nerds entertained. TestFlight users will see it first!
🔗 Just added this on TestFlight.
You can now share your train journey either as a link or straight to your Instagram story.
If you’re on TestFlight, give it a try and let us know what you think.
We’re live! 🚀 chuuchuu has officially left the station.
After months of late nights and endless data crunching, the app is finally out of beta and available on the App Store!
A big thank you to Mastodon community for the feedback that got us here. chuuchuu is better because of you. 🚆✨
Download the official version:
https://apps.apple.com/us/app/chuuchuu/id6748694096
If you want to keep on using TestFlight, please do! You’ll keep getting access to the new stuff first.
Android is up next! Stay tuned 🤖
🗺️ What do you need to navigate the chaos of train travel? Let us know, and we might just build it. Just two questions, promise: https://forms.gle/eeAXum1QT9zFq8Hn8
@pfennig@chaos.social 🥰🥰🥰 glad you like it!
🚉 Work in progress: never get surprised by a track change again! We’ve silently been tracking platform information, so we can start showing the statistics in the app.
⚠️We’re adding a little warning triangle if the chance of a track change is high, but not sure how urgent this should look. Would this startle you or is it useful?

@twobiscuits@graz.social
@twobiscuits@graz.social yeah, but there are multiple ways in which you could cross and you don’t need to catch it at a specific time. So for us it makes more sense to leave urban transit navigation to the apps that are already great at it.
🥖Working on a thing. Are there any other cities that require you to cross town to take your next train? I’m ignoring London for now.
Expansion Update🚨
chuuchuu now supports train stats for Denmark, Hungary, and Poland. 🇩🇰🇭🇺🇵🇱
Plan your journey without headaches to Copenhagen, Warsaw or Budapest.😌 🚆

@jigal@fosstodon.org
@jigal@fosstodon.org 1: if the intermediate stops were originally scheduled and now cancelled, they count negatively towards our punctuality metrics. 2: in practice those trains (I assume you’re talking about NS) still have a schedule, at least in the data we track, so there’s no difference from our point of view

@jigal@fosstodon.org
@jigal@fosstodon.org @McWabbit@tenforward.social if the train is cancelled this counts towards our punctuality metric. But if they are fully removed from the schedule then we’re not covering that yet
Replying to
@dolmen@mamot.fr
@dolmen@mamot.fr @Ja_E_I_O_U@norden.social so far it was a matter of data sources and our processing capability, that’s why we excluded regional trains. There’s a slight unfairness in the numbers as intercity trains in BE, NL and CH are more like RE/TER trains in France/Germany. Hence why next year we want be more complete.
Replying to
@danstowell@mastodon.social
@danstowell@mastodon.social @McWabbit@tenforward.social we do actually track cancellations as non-punctual arrivals. It does seem like our numbers are a bit more positive than what NS reports, so we're looking into if there's a discrepancy that we didn't see before. But overall, it seems like NS still performs better than most operators.

@dolmen@mamot.fr
@dolmen@mamot.fr @Ja_E_I_O_U@norden.social as far as I can see those trains are all classified as TER even though in practice they are long distance intercity trains. Good news is that we’re starting to track those now, so you can already see their stats on the website or app when looking for journeys!
Replying to
@PatrikSchoenfeldt@gruene.social
@PatrikSchoenfeldt@gruene.social we count a cancelled stop of a train as non-punctual, so the punctuality statistics include cancellations. For average delay metrics cancelled trains are not included though. You can also see the cancellation % in the detailed tables.

@vermeer@mstdn.social fair enough, Germany's network is way more overloaded! But that also means that train travel in Germany can be big lottery

@Ja_E_I_O_U@norden.social
@Ja_E_I_O_U@norden.social We're only showing stations where a sufficient number of long distance trains (intercity, high speed etc) pass to make it statistically relevant! Hoping to expand this to all trains in the future
We tracked like 17 million train arrivals last year to see where delays happen, and this is the result 🗺️
