Back in 2006, transportation officials and leaders in Middlesex County started talking seriously about the idea of adding a train station on NJ Transit’s Northeast Corridor line in North Brunswick. There’s no train station yet but after years of delays and more discussions, the Middlesex County Improvement Authority announced on Thursday the selection of WSP USA as the design and engineering consultant for the $50 million project. During a Zoom news conference on Thursday, James Polos, the executive director of the Middlesex County Improvement Authority, called this an important step even though it will be a while before the train station is designed and built.
