Here is the metro Images as you can see

So what i am thinking to make a metro app so i found that how to find stations between two stations. So i found that from some answers that djkshrtas algorithm i can get distance and station reach list of stations from one point to another. But didn't found that how can i implement it.

As my thinking i have to add all stations in different arrays account to line

const red_stations = ["Miyapur","JNTU College","KPHB",...,"L.B Nagar"]
const blue_line_stations = ["HITECH",...,"NOGOLE"] 

After that i am stuck as how can i combine these lines to find station as in the djkshrtas we can work on single array. Please let me anyone can explain me and provide me a logic in the javascript.

How can i find stations between Miyapur to RTC green_line as show in the map. Thanks
