The goal of 'trainR' is to provide a simple interface to the
National Rail Enquiries (NRE) systems. There are few data feeds
available, the simplest of them is Darwin, which provides real-time
arrival and departure predictions, platform numbers, delay estimates,
schedule changes and cancellations. Other data feeds provide historical
data, Historic Service Performance (HSP), and much more. 'trainR'
simplifies the data retrieval, so that the users can focus on their
analyses. For more details visit
