The conductor rail was moved from the central position to outside the running rails at the same time.

The conductor rails were fed direct, without any distribution.

In 1895 a cyclist died of electric shock after coming into contact with the conductor rail.

This allows the use of a high-voltage, insulated, conductor rail.

DC traction units use direct current drawn from either a conductor rail or an overhead line.

By using a conductor rail, the tunnel would be smaller, allowing increased clearance between the two tunnels.

This route was equipped with both overhead line and conductor rail to enable electric operation in June 1905.

It was designed to use its diesel engine when in the open air, but to draw current from the conductor rails when underground.

Wreckage from the collision short-circuited the conductor rails, tripping the power supply off.

Third-rail systems can suffer disruption in cold weather due to ice forming on the conductor rail.

During the electrification of the tunnel sections, for the first time in Germany, overhead conductor rail was installed on open line.

Originally the conductor rail was placed between the rails, energised at 500V dc.

There are few examples of overhead conductor rails in France and this is the first at 25kV.

It was originally electrified with an unusual fourth-rail system with a conductor rail outside both running rails.

However, older sections of 'M-Track' do have an actual conductor rail rather than studs.

Among the upgrades are axle counters, mounting of an overhead conductor rail, new switches and new tracks.

The conductor rail evolved into a pair of guiding rails required to keep the bogie in proper position on the new type of track.

Sleet locomotives were redundant London Underground cars converted to help with the removal of ice that built up on the conductor rails.

Third rail systems are a means of providing electric traction power to trains, and they use an additional rail (called a "conductor rail") for the purpose.

As on the District Railway the track was provided with separate positive and negative conductor rails, in what was to become a London Underground standard.

On the Hooton to Chester and Ellesmere Port line, a new aluminium conductor rail is being installed to cut electricity waste.

Some systems operate dedicated de-icing trains to deposit an oily fluid or antifreeze (such as propylene glycol) on the conductor rail to prevent the build-up.

The band (above) played Fanfare for the Common Man, conducted by Mr Davis, using a piece of environmentally-friendly aluminium conductor rail.

The trains have metal contact blocks called "shoes" (or "contact shoes" or "pickup shoes") which make contact with the conductor rail.

Electrification was cut back to Southport in the north in 1964, though the conductor rail remained until 1970 to serve the large depot at Meols Cop.
