In October 2008, the Pioneer Valley Transit Authority and the Springfield Redevelopment Authority released a redevelopment plan for Union Station. The plan, estimated to cost $65.2 million, called for restoring the 1926 Union Station Terminal building for reuse as an intermodal rail and bus station and fully building out the first floor and main concourse with rentable commercial space and ticketing and waiting areas for both rail and bus. The baggage/railway express building was to be demolished and baggage tunnel sealed. A parking garage and bus bays for both inter-city and regional bus services (which would replace the Peter L. Picknelly Transportation Center a block away) would go on the footprint of the former baggage building. Additionally the pedestrian tunnel to Lyman Street would be restored, and the platforms raised for handicapped accessibility. The final plan announced in December 2014, at a cost $75.7 million, additionally includes restoring and building out the upper floors of the 1926 station building to usable vacant "shell space". This would include only infrastructure and utility work on those floors, with final finishing work to be done by the eventual tenants based on their needs. This space is aimed for use by office or other commercial tenants. By the time the station opened, the full cost had risen to $94 million.
