Potter Street Station: the 1881 depot that looks like a castle

At the corner of Potter and Washington stands a brick building that people often mistake for a small castle: square central tower, a roofline broken by steep dormers and round-arched windows, the whole thing stretching nearly the length of a football field. It’s a train station, and it has been one since 1881.

Potter Street Station was the East Saginaw stop for the Flint & Pere Marquette Railroad, designed by New York architect Bradford Lee Gilbert and built to show off. It’s 285 feet long and two and a half stories tall — one of the largest Victorian-era depots left in the United States, and among the biggest train stations Michigan ever built. In the lumber years, when Saginaw money was flowing, this was the grand front door to the city, the place travelers stepped off into a town that thought it was going to keep booming forever.

The trains thinned out as the timber did. Passenger service ended in 1950, and the railroad kept the building as a crew base until 1986. Then came the hard chapter: a 1991 arson fire, long stretches of standing empty, the constant threat of the wrecking ball. A nonprofit, the Saginaw Depot Preservation Corporation, took it on, patched the roof with help from a state grant, and got it onto the National Register of Historic Places in 1996.

It’s still a survivor more than a showpiece — vacant much of the time, opened for the occasional event or tour. But drive past on a gray afternoon and the tower still cuts a shape against the sky that says someone, well over a century ago, expected a great many people to arrive here by rail and wanted the first thing they saw to be impressive.
