If this is the concern, then it&#x27;s a misplaced one, especially for streetcars. It&#x27;s totally common in European cities for the busiest streets (with shops etc) to be exclusively lanes of recessed rail. Trucks have no problem delivering supplies; in fact, it looked a lot more pleasant than trying to weave in and out of traffic and hope to god loading area parking isn&#x27;t blocked a la busy streets in US cities...
