LDBWS and LDBSVWS limits

[Jignesh Vaducha]

Dear All,

Are there any limits on using the LDBWS and LDBSVWS?  (I want to get live departure boards information for all stations every 5 minutes)

Thanks.

Hi Jignesh

Yes, there are limits - and this is a really inefficient way to go about what you're trying to achieve.  2500 stations in five minutes is 500 a minute, or nearly 9 requests a second.  It'll equate to 720,000 requests a day.

Have you considered using the Push Port and building your own database?  What is it that you're actually trying to do?

Hey, there are limits but they’re way higher than your use case. 5000/req per hour or 5 million per 4 week railway period. See https://www.nationalrail.co.uk/static/documents/Usage_Charging_Document.pdf

Also - if you’re developing a solution to use the data can I shamelessly plug https://api.departureboard.io that provides a restful interface on top of the National Rail API!

Also some simple python code samples: https://github.com/benjamin-maynard/departureboard-io-api-code-examples

Just read all stations every 5 mins! That’s a lot of requests, you will hit the usage limits. Still welcome to use the departureboard.io API though, we can easily handle that sort of traffic.

Thanks Peter! My aim to get 'disruption/lateness' notification(s) at each train station. The push port sends a lot of data which I don't at this stage so was thinking about using the live departure boards information to get what I need. Based the how you have calculated the numbers below and the limits, this option is ruled out. 

If I just want to get real-time disruption information (no schedule or time table, no historical information), what is the best option?
