How can u go w train from 71st continental station to 90th elmhust station

To go to 90th street Elmhurst. You take the m train & get off at grand avenue- Newtown. Then you will have to walk a little to reach 90th street.

Ms. Almas, you could take an express train, then, as per Mr. Edid's recommendation, transfer to the "R," which is a local subway train.
