I don't believe NNEPRA is going to build the new station; MaineDOT is taking the lead on the project, which I think means the station is going to be a government building. That being the case, tax-dollars-wise, the most cost-effective solution would be to renovate the existing Ferguson showroom and spend most of the money on the platforms and any track reconfiguration. And personally, I don't want to see the "urban fabric" enhanced in that location; it should remain industrial and continue to leverage the freight rail access. No station is going to be pleasantly walkable to downtown or the Old Port; the city's topography isn't conducive to that and as much as people have said that in Europe, etc., trains can do X, Y and Z, Portland certainly isn't a consequential enough market to merit trying something that capital-intensive that would potentially involve equipment Amtrak doesn't use anywhere else on its system.
