Mr Rogers' Trolley

This is a charter tram that runs frequently on Frankfurt's extensive tram network. I was lucky enough to catch it as I walked from the switch yard back to the nearest tram stop. It was still raining, as the shiny street suggests. I know very little about this tram, but the local tram enthusiasts' club in Heidelberg has a similar model that I've ridden on. I know it isn't a perfect match, but it totally reminds me of the little trolley car that starred on Mr. Roger's Neighborhood...
