Bring the thunder with General Jim’s WWII Gustav Dora Railway Cannon Gun 3-In-1 Building Blocks Set. This 3,846-piece heavyweight recreates the legendary German 80cm rail cannon, the largest-caliber rifled weapon ever unleashed in combat. Built by Germany for long-range siege warfare, this 1,300-ton steel giant hurled seven-ton shells nearly thirty miles and rolled into history as a brutal feat of wartime engineering. Though the original was demolished in retreat, its legend lives on in this massive, detailed replica. It’s a must-have build for serious collectors who like their artillery oversized and unforgettable. 

This 3-in-1 set also gives builders two alternate railway artillery options to build: the 280mm K5 (E) Leopold Train Gun and the TM-3-12 Type Railway Gun, each offering its own unique engineering style and design. Whether you assemble the iconic Dora or one of its historic counterparts, every version captures the same intricate realism and mechanical precision that General Jim’s sets are known for. 

Real-life features include an adjustable cannon barrel, loadable mortar shells, crew compartments, moveable tracks, storage boxes, and a rail-mounted carriage. The included tracks are expandable and fully compatible with General Jim’s Track Expansion Sets, allowing you to extend your railway layout or connect multiple military builds for an impressive diorama display.
