Why light rail isn't a waste of money

Last weekend a friend of mine sent me an article from The Economist talking about why trams, streetcars, and light rail are a waste of money. The argument is basically that steetcars are expensive, less efficient, and that – despite North America’s renewed interest in them – we should instead be spending our scarce public dollars on more buses.

Here’s a snippet from the article:

…but cash spent on streetcars displaces spending on other, more cost-effective forms of public transport like buses, which offer cheaper and more-efficient service but are considerably less sexy. The capital cost per mile of a streetcar is between $30m and $75m, while a rapid bus service costs anywhere between $3m and $30m, according to the American Public Transportation Association.

Now, there’s no question that buse routes are initially cheaper to implement. You don’t have track to build. But I don’t agree that the cost structure is quite that simple if you consider the number of people you need to move in your city. I struggle to see buses as a more efficient service.

The big difference between modern light rail and buses is capacity. Toronto’s new streetcars will move about 3 times as many people as your typical bus. So you’d need to triple the number of buses and triple the number of drivers – adding to your labor costs – if you want to have a chance at moving the same number of people.

Streetcars are also electric, which means they run on a renewable energy source. We’re in the process of
