"When you have metal connecting with the power rail, that's a lot of electricity."

The following table shows how many amperes are supplied by each power rail.

Workers had been instructed to work in the dark with the power rails live, even during rainstorms.

Most used a system of multiple power rails that allowed one car to speed up momentarily and move to the outside to pass.

The complex trackage remains, but the overhead power rails are long gone.

The water rose high enough on the tracks to affect the power rail and interfere with the signal system, a spokesman said.

It is being built as a high capacity, electrically powered rail mass transit system.

The railcar still holds the land speed record for a petrol powered rail vehicle.

Each of the three powered rail cars seat 74 passengers, while the unpowered car seats 80.

Its specialty is material on electrically powered rail and trolley lines.

Logic is supplied by a virtual power rail.

Also, the polarity of the power rails differs.

The plough had two metal shoes attached to springs that pushed sideways against the power rails.

Powered rail transport began in England in the early 19th century with the invention of the steam engine.

These amplifiers provide several power rails at different voltages and switch between them as the signal output approaches each level.

The latchup does not have to happen between the power rails; it can happen at any place where the required parasitic structure exists.

This included the supply and laying of 11 km of track and the power rail in the tunnel.

In these units the direct current from the power rail was converted to alternating current powering induction motors.

This can be particularly useful in single-supply systems, where the negative power rail is simply the circuit ground (GND).

Almost all integrated circuits (ICs) have at least two pins that connect to the power rails of the circuit in which they are installed.

However, MD 180 remained the only link to the closest steam powered rail station in Brunswick.

A spring that pushes the shoe up against the power rail is more exposed to snow than on other models, resulting in broken connections and short circuits.

The system delivered current by overhead conductor wires and was cheaper than alternatives using power rails and required fewer electrical sub-stations.

In April 1998 EWS took over the National Power rail operations.

Traction motors are used in electrically powered rail vehicles such as electric multiple units and electric locomotives.
