I am trying to find a mechanism to retrieve the full list of TfL stoppoints so that I can cache them and avoid the use of API calls. I am testing using the /StopPoint/mode/{mode}, with mode=“tube”. This returns 1700 StopPoints! I understand that the majority of these are platforms, bus stops etc… but the stoppoints are not returned in any useful hierarchy that I can fathom.
Using a bit of a “sledgehammer to crack a walnut” approach, I saved the JSON response from the URI above, and have tried parsing this into an object graph but I can’t find a natural primary key. Even “id” is producing duplicates…
In short, if I wanted to start a project by finding a list of all Tube stations (not platforms), how can I successfully whittle down the results of /StopPoint/mode/tube to give me just ~270 results?
I have the dataset to hand, so I can spot that the you’re probably looking for locations with a prefix of 940GZZLU however, locations that are tube and rail will start 910G

There’s a bit of mess in the data (I’ve posted some of the issues on here, but there’s doesn’t seem to be a lot of interest in fixing them), but it’s not too terrible to deal with.
What language are you using? My code is in JavaScript / Node.js - I’d be happy to share if it would help.
I didn’t use the lines but just did stop points by mode, and filtered on stop type, then cleaned up the weird cases.
Thanks for your reply. PHP isn’t my strong suit, but by the looks of things you’re keying the collection on the “id” attribute of the StopPoint? Are these unique across all StopPoints or only within a single mode? I follow your method, just thinking about whether I need to be storing different the StopPoints for different modes in different tables in my data store to avoid a duplicate key?
Thanks for your reply. Did you use “NaptanMetroStation” for your type filter?
I’m writing in C# on .NET Core (I know…) but also considering swapping to Node.js to learn something new! I’m considering releasing my wrapper around the API as a package for other .NET developers - but I guess consuming the API is very different to understanding the results!
Yes, it depends which modes you’re looking at, I’m currently only looking at tube, dlr and overground. For tube and dlr you want NaptanMetroStation and for overground you want NaptanRailStation.
I’ve just checked and that part of the code is very simple and probably not worth sharing. I also wanted to know all the lines (including overground and dlr) serving each station and all the entrances, for which you also need to look at the TransportInterchange stop types. That’s where most of the complexity is.
The basic structure is that all of the stop points are at the root level, and where they are logically children of the other stop points they are also included in a nested hierarchy. Issues I’ve seen are:
Stations not necessarily including DLR and/or overground where they’re present in the lineModeGroups (or other equivalent orderings of lines) - you can get them via associated TransportInterchanges though.
Entrances not consistently associated with the relevant metro or rail station - there are a few(?) just missing, but mostly they’re either on the metro station or the rail station, so as long as you just want everything for one station you can merge them (and some are on both so remove duplicates).
Wimbledon has a weird extra NaptanRailStation with no entrances between the TransportInterchange and the actual NaptanRailStation with entrances, so you have to go down an extra level.
If you are merging lines for tube, dlr and overground like I did, what’s included where is not consistent, so you will need to just merge everything and remove duplicates.
You don’t really need to know the NaptanMetroStation as you don’t need to filter by it. As per the demo code you are looking for tubeStopPoint->modes (tubeStopPoint.modes) having “tube” in it.
I’ve re-written it in synchronous Javascript, perhaps that makes it clearer?
var QGTS = new function () {
this.arrFound = [];
this.execute = function (mode = "tube") {
var httpRequest = new XMLHttpRequest();
httpRequest.onreadystatechange = function () {
QGTS.alertNewLiveData(httpRequest,mode);
};
httpRequest.open("GET", "https://api.tfl.gov.uk/line/mode/" + mode + "/status", false);
httpRequest.send("");
for (var key in this.arrFound) {
console.log("key " + key + " has value " + this.arrFound[key]);
}
}
this.alertNewLiveData = function (httpRequest,mode) {
if (4 === httpRequest.readyState) {
if (200 === httpRequest.status) {
var tubeStatus = JSON.parse(httpRequest.responseText);
tubeStatus.forEach(element => {
var httpRequest = new XMLHttpRequest();
httpRequest.onreadystatechange = function () {
QGTS.alertNewLiveDataInner(httpRequest,mode);
};
httpRequest.open("GET", "https://api.tfl.gov.uk/line/" + element.id + "/stoppoints", false);
httpRequest.send("");
});
}
}
}
this.alertNewLiveDataInner = function (httpRequest, mode) {
if (4 === httpRequest.readyState) {
if (200 === httpRequest.status) {
var tubeStopPoints = JSON.parse(httpRequest.responseText);
tubeStopPoints.forEach(
tubeStopPoint => {
{
if (tubeStopPoint.modes.indexOf(mode) > 0)
this.arrFound[tubeStopPoint.id] = tubeStopPoint.commonName;
}
});
}
}
}
}
QGTS.execute();

You don’t need to know the station stopType if you’re getting the lines first. However if you get the stop points by mode rather than line, you only need to make the one API call and then filter by the stopType (this is in fancy modern JS and uses a couple of modules to keep your secrets in environment variables and make the http request a bit nicer):
import axios from 'axios';
import dotenv from 'dotenv';
dotenv.config();
const app_id = process.env.APP_ID;
const app_key = process.env.APP_KEY;
const fetchData = async (mode) => {
let result = await axios.get(`https://api.tfl.gov.uk/StopPoint/Mode/${mode}?app_id=${app_id}&app_key=${app_key}`);
const stopPoints = result.data.stopPoints;
const stopType = mode === 'overground' ? 'NaptanRailStation' : 'NaptanMetroStation';
const stations = stopPoints.filter(sp => sp.stopType === stopType);
// map through the stations and grab the stuff you want from each and then return it
// unless you really want the whole thing, which you probably don't, it's enormous
}
const getStations = async () => {
let stations = await fetchData('tube');
const dlrStations = await fetchData('dlr');
const overgroundStations = await fetchData('overground');
// do something with the station data - I merge it and put it in a JSON file in S3
// you might have something else you need to do here
}
getStations();
I guess the issue here is, when you have no idea what the poster was trying to use for their code, whether to go for something explanatory like pseudocode, or try to show some actual working code, even though it might be less than clear.
I must admit that I personally find that conditional operators make unreadable code…
whilst others don’t like language-specific shortcut functions like in_array
if (in_array($strMode, $tubeStopPoint->modes)) ...
And then there is the Javascript dotted notation vs → for PHP. Anyway, I’m always interested to see what people use.
Going back to
I’m writing in C# on .NET Core (I know…)
I fired up Visual Studio and I got stuck as you can’t decode JSON in .NET core as far as I can see. This was a far as I got trying with VB.NET
Imports System.Net
Imports System.IO
Module TfLStationNames
Sub Main(Optional mode As String = "tube")
Dim request As HttpWebRequest = DirectCast(WebRequest.Create("https://api.tfl.gov.uk/line/mode/" + mode + "/status"), HttpWebRequest)
Dim response As HttpWebResponse = DirectCast(request.GetResponse(), HttpWebResponse)
Dim reader As StreamReader = New StreamReader(response.GetResponseStream())
Dim rawresp As String = reader.ReadToEnd()
End Sub
End Module
Thank you both for your comments, each approach has helped me reach a solution in .NET Core.
@markw I was using a method similar to yours to begin with, getting in via the /StopPoint/Mode/{mode} endpoint as it seemed to use fewer API calls. The const stopType = … line was particularly useful for me, as that allowed me to filter down to ‘NaptanMetroStation’ to retrieve just tube lines. Obviously I’ll need a switch to deal with other station types later if I implement London Overground etc…
@briantist Your example worked wonderfully in my head, but required a few more API calls (I’ve already had an email from TfL for hitting 500 requests a minute in an early version of my code!) so I was keen to be lean. Not sure if you plan to do much .NET Core, but there is a library you can import using NuGet called System.Text.Json which will let you work with JSON easily. There’s also a library for consuming REST APIs called RestSharp. Combined together, consuming the TfL API is relatively straight forward but still far more complicated than it is in PHP! By way of example (with some boilerplate code missing), I can get the list of Modes from /Line/Meta/Modes, and return a strongly typed collection from the decoded JSON, using:
public async Task<List<Mode>> GetModes()
{
var restRequest = new RestRequest{Resource = "/Line/Meta/Modes"};
var result = await _client.ExecuteAsync<List<Mode>>(restRequest);
return result.Data;
}
I’m glad you got it sorted, and thanks for your kind comments.
It’s worth reiterating @markw that it’s always worth storing this kind of static data on your own server, as it keeps down the number of API calls. Most of my code for TfL passes through a memcached interface, so that I can correctly cache things for as long as it necessary. I think new tube stations come along every decade or so, so caching the names for a week isn’t going to hurt. Holding the data on S3 is a great idea for Android/iOS app, memcached for my Ajax/PHP web apps.
