The DATEX II v1 service from NTIS was switched off at the end of September 2016 after 3 months consecutive emails to subscribers who have not migrated to the replacement DATEX II service. To help you migrate to the new DATEX II service, all of the design documentation and sample code in Java and ASP .Net and a JSON Toolkit is available on the subscriber pages of the new Traffic England website at http://www.trafficengland.com/subscribers.

The term "Web Services" is used generically here, since profiles for the Web Services protocol stack (WSDL & SOAP) as well as plain HTTP exchange options are provided.
2 files describe the WSDL services, one for the Pull operating mode, the other for the Push operating modes.
You can download the 3 files together in a zip file from the link below.
