The LRT cars will last for much longer than buses so their higher costs end up deferred over many more years than a bus fleet. Rubber tires wear out faster and there's still ground level pollution from dozens of buses going up and down King street with a busway, LRT should help local air quality. Rails will probably last longer than a busway, and probably end up similar in costs if rebar and concrete are used.
