As you may have heard, the Department for Transport is redeveloping the NaPTAN (and NPTG) service. We have conducted some initial research and concluded that it needs to be more reliable and adaptable so it can continue to be useful, now and into the future. Due to the age and design of the system, incremental improvements are not practical, so we are planning to completely rebuild the service.
