The Electro-Magnetic Laboratory Rail Gun is a long-range naval weapon that fires projectiles using electricity instead of chemical propellants. Magnetic fields created by high electrical currents accelerate a sliding metal conductor, or armature, between two rails to launch projectiles at 4,500 mph to 5,600 mph. Electricity generated by the ...
The magnetic flux crosses the rail in a direction transversal to the first axis and creates a closed-loop on the U-shaped profile. This configuration generates a stable equilibrium along the first axis that maintains the rail centered on the flux crossing point (minimum magnetic reluctance) and allows to bear a load magnetically.
Externally, the rebuilds have received new wide-nosed cabs, a new front hood section, and a new inverter cabinet behind the cab, while retaining the underframe and engine and radiator compartments of the original Dash 9 units. Rebuilding an old Dash 9 locomotive into an AC44C6M costs only 50-60% that of purchasing a brand new AC locomotive. [3]
[4] In the off position, the poles are oriented towards the non-ferrous core. The iron blocks act as keepers by bridging between both poles. In the on position, the poles are each in one iron half, which then acts as an extension. The field is effectively passing across an air gap (at the base and top).

The AC4400CW was the first GE locomotive to offer an optional self-steering truck design, intended to increase adhesion and reduce wear on the railhead. [1] This option was specified by Canadian Pacific Railway, Cartier Railway, CSX for their units 201-599, Ferromex, Ferrosur, and Kansas City Southern Railway.
Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.
The GE Dash 9-40CW is a 4,000-horsepower (3,000 kW) diesel-electric locomotive built by GE Transportation Systems of Erie, Pennsylvania, between January 1996 and December 2004. 1,090 were built for Norfolk Southern Railway, as road numbers 8889 to 9978. 53 GE Dash 8-44CWs built to Dash 9 specifications were also built for CSX Transportation, carrying road numbers 9000 to 9052.
