('No trip_id for ', '534')

[ExtremeMemes]

Hello! I was playing around with timetable kit today, and when I was trying to generate some timetables, I ran into this error. For some reason, only train 534 will not generate the timetable. Can you help me resolve this?

Below is the command I used and the output

timetable.py --spec capitol-corridor-weekday-eb.csv capitol-corridor-weekday-eb.json -o output -a Extreme

Output

Please share the exact version of the GTFS dataset you're working with, e.g. the URL you downloaded it from; Or if the URL always points to the latest version (so you might have an older one), please upload it somewhere.

Hello,

I can look later today, but in the meantime try using a different reference date in your command. The help file should have the sample syntax for specifying the reference date. Sometimes you have to try a reference date for each day of the week to see what works. It's an Amtrak data 'feature'. (I'm also not the author but have worked with them on this project).

@juckins Thank you for the tip, Changing the reference date helped, and the timetable did generate.

Also I have tried to generate the Vermonter timetable, and I have also tried changing the reference date, but It seems like there is a separate schedule for the weekday and the weekend train, so I cannot use the same reference date for how would I be able to generate that to the same page? TLDR: Looking for a way to use two Reference Dates in 1 command/run so that the trains which are on different days (M-F&SaSu) can be on the same page.

@juckins It also seems like you managed to get the vermonter trains which run on different dates on 1 timetable here

May you tell me how you accomplished this

@ExtremeMemes I know the author got that to work by making unique edits to the .csv file for the Vermonter. Try opening up that csv in a spreadsheet program like Excel where you can easily view the rows and columns. Study the setup, and I think that will get you going. I don't think more than 1 reference date was used on the command line, but I have to check on that. Let me know if you get stuck and I can look more this weekend. Amtrak data can be a challenge to work with.

Separately, I'm having a problem downloading the Amtrak stations and I need to see what's going on there. It errors out after processing 1 station.

THANK YOU! Your help @juckins helped me a lot.

What I had to do is change the Reference Date (To a weekend), and I had to modify the first and second rows to something like this:

Row 1- | 55 monday | 57 | access | station | 56 monday | 54
Row 2- column-options | ardp MoTuWeThFr | SaSu | blank | blank | reverse ardp MoTuWeThFr | reverse SaSu

Also used the tt-spec docs to help myself out

For your problem of downloading Amtrak stations, have you installed all of the requirements? If that does not work, can you create a new issue, (to keep this organized) and I will try to help you there

[juckins]

@ExtremeMemes Glad to help, and I got the stations working, it may be an oddity in my environment or local python patch. Thanks!
