While vainly searching for hot deals for this up coming holiday season at Lego Shop at Home, your author shockingly stumbled upon a shocking discovery. While the Cargo Train Deluxe set, 7858, may seem like an ordinary train set, upon further inspection it seems the Lego designers have blatantly ripped off a fan's design for the boxcar included in it. The boxcar to which your author refers is in fact several boxcars, all sharing similar characteristics, but built by one person: Reinhard "Ben" Beneke, known simply as "Ben" on your favorite and ever reliable site Brickshelf.
Here, readers, is an image of the boxcar included in set 7858 and following it are several images of the boxcars on whose design it was based (note the similarly sloped roofs, doors, and number of wheels):
It is really unfortunate when Lego designers resort to blatantly stealing fan's designs, without giving them any compensation, let alone credit.
