Your blogger, like many readers, is intrigued by the renovation work going on at the Union Depot train terminal.

Earlier this year, the Star Tribune profiled the progress of the $243 renovation in photographs. The Lowertown complex will eventually become a multimodal transit hub, accommodating Amtrak, light rail, bus, car, bicycle and pedestrian traffic.

But now, the Ramsey County Regional Railroad Authority is inviting artists to apply for public art commissions at the historic neoclassical facility. The Authority is investing about $1.25 million towards public art in the space -- $1 million of which comes from the Federal Transit Administration.

The Federal Transit Administration believes "the visual quality of the nation's transportaiton system has a profound impact on making a vibrant, safe and welcoming facility," according the the Railroad Authority's news release.

There are four key areas slated for public art at the Union Depot. They include:

1. A mural to greet passengers arriving through the lower-level carriageway driveway.

2. Artwork in the atrium space that serves as an entry to the Great Hall.

3. Artwork to span the multi-story entry along Kellogg Boulevard.

4. A building-wide interactive multimedia art platform that would launch once the Depot renovation is complete.
