Hi. It seems the only way to retrieve a routes lat/long in order to plot it in its entirety is to use e.g.
https://api.tfl.gov.uk/line/161/route/sequence/outbound
and then chop up the the single element stored in the lineStrings array.
e.g.
“lineStrings”: [
“[[[0.075038,51.412448],[0.074979,51.412413],…[0.074626,51.412230],[0.073659,51.412796]]]”],
Is that the approach used by other people in this forum?
Thanks,
Steve
