When chilling winds blow and the temperatures drop, Metro Transit riders appreciate the warmth put out by overhead heat lamps on light-rail platforms and in bus shelters.
But in many cases, the mechanisms have not been working. Hundreds of the heat-producing units have been vandalized, and that's left riders like Kim Johnson, of St. Paul, shivering in the cold.
"It's not like a weenie roast with that heat, but it really makes a huge difference," said Johnson, a daily Green Line rider. "When we have those brutal days, it's uncomfortable. They take the edge off."
So Metro Transit this fall began installing stainless steel covers over the warmers to prevent criminals from smashing the 12-inch glass tubes that put out heat.
The grates were designed by Metro Transit electrician Jim Davis, who sought a solution to the persistent problem of fixing a unit only to have to return within days or weeks to make the same repair.
"We hope this can help us out," said spokesman Howie Padilla. "We know riders are out there and it's getting cold."
So far the agency has installed about 100 of the protective guards at bus stops along Marquette and 2nd avenues in downtown Minneapolis, and at some light-rail platforms.
If they prove successful, the heat lamp covers could be installed on more of the agency's 1,500 heaters, Padilla said.
