Is there elevator or escalator service for the A train at the 68th street station?

Yes there are 4 large elevators, no escalators. Elevators are the ONLY way to get to the lower subway track of the 1 trains. BUT now, for the next few months, until sometime in 2020, the 168 Street Station is skipped by the 1subway trains! The elevators are under renovation! There is a shuttle bus from 157 Street Station.

You mean 168th? Yes there is an Elevator.

Of course!!

Yes
