My father and grandfather before him had shell gas stations longer than I've been alive. In 1995 Shell Oil partnered with Atlas to produce these collectable promotional train sets (also sold individually) for the holiday season. I am helping my dad clean out all his old Shell stuff, and came upon these. I also have a ton of shell LEGO sets too. Anyway, this set includes all 4 unique pieces, still sealed in original bags with their instruction flyer included. I am also offering a number of these items individually.
