However, the Great Depression, a post-World War Two switch to mostly natural gas and electric heat in American homes, and heavy industry ’ s lessening coal use doomed the area coal fields.

Two failed immediately in the 1850s, but the electric line carried supplies to the village and fort as well as bringing thousands of people to the old beach amusement park.

Two guitars were used, often one acoustic and one electric, and a variety of effects.

Two City Line branches are currently being electrified on the overhead AC system with completion planned for 2016, which will give an almost completely electric network.

Two types of trains are used, an older type consisting of an electric locomotive with double-decker cars, and Electric Multiple Units where the motors are on board the car.

In addition to original material, their set list included extended covers of Steppenwolf's " Born to Be Wild ", The Jimi Hendrix Experience's " Purple Haze ", Moby Grape's " Hey Grandma ," The Lemon Pipers ' " Blueberry Blue ," The Doors ' " Love Me Two Times ", and an electric version of " Debora " by Tyrannosaurus Rex.

Two mechanical elements, one that is stationary ( the stator ) and one that is movable ( the rotor ) have two different voltages applied to them, which creates an electric field.

Two factors limited the widespread use of electric headlamps: the short life of filaments in the harsh automotive environment, and the difficulty of producing dynamos small enough, yet powerful enough to produce sufficient current.

The Behn Brothers also built their home in Condado and to their memory Two Brothers Bridge or Puente Dos Hermanos is named in their honor as founders of Puerto Rico Telephone and the new electric tramway line that linked the county to Old San Juan.

Two different basic designs have been invented for high-acceleration linear motors: railguns and coilguns.

Two 300 kW DC motors were installed to drive the cable.

* Propulsion: Two side-mounted ramjet engines ; four solid propellant boost motors

Two three-phase induction motors.

Two contra-rotating gyros were housed under the front seats, spun in a horizontal plane at 3500 rpm by 24V electric motors powered from standard car batteries.

Two generations of the Revopak were produced-the early 1971-1973 models used hydraulic motors which drove the compaction rake by means of chains, while the later models utilised a simpler and more robust drive system which consisted of twin synchronised hydraulic rams to operate the compaction system.

Two key performance parameters of brushless DC motors are the Motor constants Kv and Km.

Two important performance parameters of DC motors are the motor constants, K < sub > v </ sub > and K < sub > m </ sub >.

Two Moorish styled chimneys – unused since steam power had been replaced by electric motors in 1933 – were demolished in 1941, as it was feared that a bomb strike from German bombs might topple them on to the pumping station.

Two versions of the North American NVCS version exist: earlier motors used pistons with two compression rings and a single oil ring and put out five less horsepower, while later GA16DEs have a single compression ring and a single oil ring.

Two main versions will be produced: an oil-bathed " wet " multi-plate clutch version which utilises hydraulic fluid for shifting, and a " dry " single-plate clutch version which uses electronic motors to control the transmission.

Two driving motors have been preserved.

Two Brush built 1915 Stock ( also known as ' Ealing Stock ') driving motors, numbered 3937 and 3941, which had been withdrawn from the Central London line, were converted into the electro-diesel locomotive.

Two electric motors were situated at the rear of the car, produced 2. 5 hp ( 1. 9 kW ) each.

Two Mark 75 motors set an endurance record by running non-stop for over over 68 days on Lake X.

Two locomotives SNCF BB 20011 and 20012 were used to develop and test the dual voltage traction system, microprocessor control systems and auxiliary motors, BB 20012 was used to develop and test the pneumatic and electrical braking system.
