I am planning a trip in April where we are driving from Pittsburgh to Niagara Falls for a day, then riding the Empire Service train from Depew to NYP, returning a couple days later via the Maple Leaf. I have seen that parking is available at Buffalo-Depew, but is it likely to be full? We would be departing at 7:30 AM on a Thursday. I could make alternate parking arrangements at nearby airport parking lots and Uber to the station if needed, but obviously it would be more convenient to park at the station.
