In the Discovery Channel series, host Morgan Freeman explores universal mysteries: truth, life and coincidence. And it just so happened the crew was filming Monday at the Baltimore Streetcar Museum when a small fire started.
Weekdays, the Falls Road museum is usually closed and empty. But volunteers were there about 7:30 p.m. for the filming. Bob Krueger noticed smoke and ran for a garden hose.
Out back, the mattress where a man sometimes camps was burning. The fire jumped to the museum canopy.
The mattress was "fully engulfed as the firefighters would say," said Krueger, who is not a firefighter, but who staved off the flames with his garden hose. Ashes flecked his cheeks.
Inside were the model trolleys, historic photographs and minutes from transit company meetings — a library of relics from bygone days when 500 miles of rails connected Baltimore and 710,000 people rode daily.
