Baltimore had 440 miles of fixed rail in the past

Baltimore Sun: "During the last century, Baltimore had one of the nation's leading trolley systems, with over 440 miles of fixed rail serving us in the city and suburbs, going in all directions. Along Baltimore City's hundreds of miles of streets today, we have only about 20 miles of Metro and light rail within city limits to serve us as fixed rail public transit. These two lines generally go from north to south across the city."
