Wondering when your train will come will get a little easier for straphangers in Astoria, according to transit sources.

Five Queens subway stations will get a system starting tomorrow that makes announcements when the next two trains are coming.

Although riders won’t get countdown clocks, they will know at least when the next N or Q train is arriving, sources say.

The 39th Avenue, 36th Avenue, Broadway, 30th Avenue and Astoria Boulevard stations will have the new announcements.

Although numbered lines like the 2 and 3 have countdown clocks, most lettered ones do not have announcements for riders, sources added.
