With the debut of service on the new, $1 billion “Green Line” light rail train this weekend, I find myself trying to sort out some surprisingly deep feelings that have sprung up from the well of old St. Paul memory and pride.

University Avenue will carry more than sleek trains covered in slick corporate ads. It has always carried family histories and deep-seated associations – good and bad – of life in St. Paul, where University Avenue once was the main route of passage through town. And may become once again, at least symbolically, with the arrival of the new-age street cars after an absence of 60 years.

I am told I rode on one of those last University Avenue street cars in 1954, a four-year-old carried on the lap of my Irish-born grandmother (She would have approved of a “Green Line”) who learned when my father was a baby that a brief street car trip up and down University Avenue was the perfect sleeping tonic for a fussy baby. A few years ago, as crews were ripping up six decades of asphalt to make way for the new train, they discovered forgotten veins of granite cobblestones, some of them with grooves machined into them to hold the old street car rails. Strangely overcome, I bought a bunch of the heavy stones for $2.50 a piece and took them home, my car’s suspension bottoming out, using them to edge my garden. The stones my grandmother and my father and generations of my family passed over for years, carrying their hopes and their worries, and carrying me.

The 4th & 5th generations of St Paul Colemans to ride the rails on "the Avenue" try out the new Green Line Saturday, June 14.

It’s hard to exaggerate how important University Avenue is to St. Paul, even if it has been by-passed by the multitudes driving in the blind trench of Interstate 94 in recent decades, traveling through the heart of the Capital city with hardly more to see than car-blown litter, scraps of truck tires and graffiti on a railroad overpass or two.

I-94 is a blank tunnel. University Avenue — the Central Corridor — was the artery, carrying not just cars, but life.

My mother was born in the intersection of University and Rice Street, in the back seat of a police car racing to the hospital but arriving 10 minutes late. Her parents had a small grocery on the south side of University, at Farrington, living above the store on the edge of Rondo, the impoverished but proud integrated neighborhood nearly erased by the big ditch that was dug to build the freeway. On the other side of University is Frogtown, where my father grew up, his dad working for the railroad, his mother selling scarves downtown. Connecting the two neighborhoods, and separating them as well, the street cars unknowingly bound the two families together. My mother’s stepfather, Abraham Levenson, from Lithuania, riding the same cars Hannah Kennedy Coleman, from Ireland, was riding. Those connections eventually would lead to a marriage, and to me: They were forged at the end of the line, downtown at The Golden Rule, the department store where my grandma worked and my mother was trying to get hired as a store model. She seemed like just the right girl, my grandmother thought, to introduce to her son.

So I’m pretty sure I wouldn’t be here if they had all been driving on I-94. And maybe you wouldn’t be here, either.

My brother – the one who is mayor – will be part of the opening ceremonies Saturday at The Union Depot in downtown St. Paul. But he won’t just be cutting the ribbon as an elected official. But as a descendant of a century of immigrant families -– Colemans, Finnegans, Levensons, Alfords and more – who found their futures in a St. Paul where there were no “fast lanes” or chauffeured Town Cars, just an egalitarian, everyone’s-equal transportation system where they took their seat, or held on to an overhead strap, to make their way in a city where they were as welcome as anybody else. And where, often, they came to know just about everyone else. It’s ironic that, as America becomes more and more divided in terms of income equality, light rail returns to a street where it once helped build a city.

We need it to work again.

University Avenue does more than connect St. Paul and Minneapolis. It has connected people and their stories, and, ultimately, their family histories. Here’s hoping the Green Line prods a few of those drivers on I-94 to look up and see where they are. And to take a chance on the light rail.

You never know where it might lead them.
