These anti transport mines have a built-in electrical detonating circuit, consisting of one or more flashlight batteries, an electric detonator inserted into the charge, and a pressure type contact fixed to the top of the mine or separate from, but wired to, the mine. A typical electrical pressure anti transport mine is a plywood box, 5 1/2 to 6 inches long, 4 1/2 to 5 inches wide, and 2 to 3 inches high. In the box is an explosive charge, usually from 300 to 500 grams in 100, 200, or 400 gram blocks.
This mine is normally used against trains and is laid on a large charge buried in a railroad bed so the push-button contact is just below the rail or tie. The mine may also be used as a road mine.
This type of mine functions only by pressure on the push button contact which closes the circuit.
