Damage 10d4 (SP: 20d4) sonic; Range special (25,000 ft.)
The railway gun is an enormous metal structure, about 155 feet long, 23 feet wide, and 38 feet high, from which extends a long, movable metal barrel. The railway gun can travel along pre-laid tracks (such as those suitable for trains) at 120 feet per round, or overland at 24 miles per hour. Some are built to move off of tracks. This weapon requires the presence of magic to move, but does not otherwise require fuel. As a Destruction spell engine, the railway gun possesses the Calamity (blast shape), Explosive Orb (blast shape), Extended Range (2x), Extreme Range, Gather Energy, and Shattering Blast (blast type) talents, as well as the Extended Casting (2x), Energy Focus (sonic), and Shape Focus (Explosive Orb) drawbacks.
When fired, the railway gun can target a 5-foot square within its range, spend one spell point to target a circular burst with a radius of up to 30 feet, or spend two spell points to target a circular burst with a radius of 75 feet. This blast deals sonic damage, does full damage to objects, and ignores up to 10 points of hardness. The railway gun normally takes a full-round action to fire, but can extend its activation time to 1 minute to reduce its spell point cost by one. Creators - normally countries who have the budget to invest in such weapons of war - often look for ways of further increasing the range of a railway gun in order to maximize its war potential.
