over the past couple days ive collected some data to understand better the API, when it comes to tube (not tested this on the other modes yet) there is a clear theme with how current location is presented with the main ones obviously being: At, Between, Aproaching, Left, Leaving. However ive spotted a number of current locations that seem irregular, if anyone could shed some light on any of these different types of current locations, and also if anyone knows of any other types of irregularities that current location can have that i have missed off please let me know as this is only a day or two worth of looking. They are as follows:
does departed and left (also departing and leaving) mean the same thing?
0: seemingly only on victoria line?
What is the North and South prefix for? its used even when the tube is approaching the next station from a different direction i.e. North if Queen’s Park, is it implied diection from route? and where do they fit in with the other states such as between, approaching, etc
What is meant by the area and Area postfix?
Finchley Central Platform 3: anyone know why this is returned next station can be several north northernline stations
In between Goldhawk Road and Hammersmith (also In between Wood Lane and Latimer Road): Is it only in these places In between is used over Between?
In the vicinity of Hammersmith Platform 3: weird response with this sometimes wood lane or latimeer road rather than goldhawk road
Kennington Loop: not sure on this
Lillie Bridge Depot and Stonebridge Park Depot: assuming just a depot for trains and not relevant to live service?
What is meant by the Siding and Sidings prefix and postfix?
What is meant by On P[some int] crossover / how many crossovers are there?
Queen’s Park Reversing Berth
Any help appreciated!
