have you guys thought about compressing these? either as a zip file, or on-the-fly in the webserver?

i get that “Rail” includes non-cityrail/non-railcorp modes like Sydney Metro. but why doesn’t “Rail” include “Light Rail”?

😛 is it because “Light Rail” should be called “Tram”?

Hi Jayen,

Light rail data will be made available in due course.

Thanks @jayen for the suggestion. We have decided to leave it as text files.

you can serve them as text files and have them compressed or pre-compressed on the web server. so, data consumers will see them as text file, but they’ll download 10x faster and cost 10x less to host and transfer.

Thanks to feedback, we are refreshing the ROAM files – we will advise when they have been refreshed (We estimate this will be completed by COB 18 September 2020).

Once refreshed there will be a new row per trip segment indicating occupancy for the whole train set.

We will update here once we are aware that all files are refreshed.

The ROAM files have been updated and now include an “all passenger” occupancy band.

We have been advised that the data from 18 October 2020 onwards at this point is unreliable due to upstream systems. Please use the data with caution.

We will update here when we hear further about the data updates/fixes.

There are ongoing issues so extracts to FOAM, BOAM and ROAM have stopped. A catch up set of data will be produced once upstream issues are resolved.

Hi There, there are a number of missing days in the ROAM data from October and November last year. Is this data available and is there any chance it could be added for these days?

The missing days are 10 and 21 October and 12 and 21-26 November.

There was a fair bit of industrial action around that time. 21-26 November I think the gates were open and the ROAM data is based on Opal card usage, so there likely isn’t data for at least that week.

Recent updates to the GTFS metro feed from v1 to v2 have impacted data feeds from the 26 March 2024 to date. As such the boarding and alighting data Metro services are not currently displaying in the Rail Opal Allocation Model (ROAM) updates.

The data operational support team is currently working to revert the recent changes and restore the ROAM over the coming Easter long weekend.
