Here's a CAD model of the Luas I've been working on this past week. It's based on the five car Citadis 401 trams that are currently used on the Green Line. So far I have added no interior details, but might do so during the week. There is a 9V motor in the front car and all the other cars have the small train wheels. The roof is mainly a plain even surface unlike the uneven surface of the real tram roofs. I'm not sure yet if I'll change it. Your comments are welcome.
