Our Data team have physical TransXchange files, which we do supply to a number of stakeholders, usually for inclusion in third party systems. These contain all the data required, both timetable and mapping, for each individual service in Wales.
The TransXchange files are freely available, however if you wish to access them, please contact our Data team at firstname.lastname@example.org and we can arrange the best method of transferring them over to you.
For more information of TransXchange, please follow the Department for Transport link here: https://www.gov.uk/government/collections/transxchange
