It looks a lot smaller then the original Transporter though; while I don't remember seeing stats, I always had the impression that the original Transporter was a bit wider than a Cobra III, but four times longer. By my recollection of the Lore, the Transporter was designed to shuttle cargo between station and surface; the Worm Shuttle carried passengers, and was much more the size of your ship.
I only remember this because every time I see advertisements for the Volkswagen Transporter (a van that's often sold here in Australia as a people-mover), I always find myself thinking "no, that's not right, the Transporter is supposed to carry freight, not passengers". It takes me a while to figure out why my subconscious is making me think this; it's because of all the Elite I used to play back in the Commodore 64 days.
