Other features of the widget will include real-time status updates for the Tube, the DLR, buses and London Overground. The application will be able to store a snapshot of the latest status update, viewable without a signal, even when underground.
A number of agencies have already been approached and the process is at the tender stage. However, TfL is hoping to move quickly and have a finished product available by the middle of October.
The official TfL widget, which will be compatible with iPhones and BlackBerrys, is being produced in response to a number of unofficial travel information applications that are already available.
The government department feels that the unofficial applications either use information scraped from the TfL website or are providing inconsistent, inaccurate or misleading information. The application will be advertised on the TfL website.
