LIRR API does not show track number which have been announced

[Zahidur R]

I’m using the API https://backend-unified.mylirr.org/gtfs/lirr, but it doesn’t display the track numbers once they’ve been announced. 

In the screenshots, the left image shows our app and the right one is the LIRR departure board. 

The right-most column in our app’s screenshot doesn’t show the track numbers for announced trains, unlike the LIRR board. Is there a solution or perhaps a new API that could provide this?
