Lionel used the center rail for power and the two outer rails for ground. For example, with a three-rail system, the track can loop back on itself without any issues. A two-rail system has to reverse the polarity in order to avoid a short circuit in that situation. In 1906, there was no good, easy way to do that.

Why do some model trains have 3 rails?

In the early days of railway modeling, some O scale modelers (the dominant scale at the time), made use of an outside third rail and a shoe pickup system for power. This system had the benefit of being more realistic by removing the central third rail common to O scale track, while retaining an effective power source.

What is the purpose of third rail?

Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a conductor rail) for the purpose. On most systems, the conductor rail is placed on the sleeper ends outside the running rails, but in some systems a central conductor rail is used.

Will you die if you touch the third rail?

– The third rail looks like a normal railway rail, but is electrified. The electricity is so strong that if you touch the rail, you will be seriously injured or killed. – Electricity in overhead lines can jump. You dont have to touch the overhead lines to get electrocuted.

What is the difference between O gauge and O scale?

In general use, O gauge refers to 3 rail model railroading made popular by Lionel. O Scale refers to trains that run on 2 rail O track. The term O Scale also is used to designate a commitment to scale size reproduction of real life in a scale of 1:48 size, the ratio between the real world and the model.

Is O scale bigger than G scale?

G gauge is approximately double the size of O gauge in all directions. A G gauge train by strict scale definition ought to be 1:32 scale, but most G gauge trains are bigger. LGB scales its trains at 1:22.5 scale, and Bachmann and other companies followed LGBs lead.

Which is better third rail or overhead?

At the least a human who touches the third rail is seriously injured. Overhead power is much less dangerous to both railway workers and to trespassers. The high voltage (3,000–25,000 V) is on a railway a minimum of 22′ above the rails. It may be lower on light rail and street railways.

Is the third rail always live?

Conductor rail safety is designed around our staff, who are trained to work on track. The live rail is split into electrical sections that can be isolated from each other, while allowing power to flow to other parts of the railway. However, trackside workers are trained to assume the power is always live.

Can you pee on train tracks?

While it is possible, a 2009 Mythbusters found it would be incredibly unlikely in practice. When people pee, it often dribbles, as pictured in the GIF from the show at right. To conduct electricity, one would have to reach a League of Their Own stream levels.

Has anyone ever survived the third rail?

Andy Morris hit an electrified third rail after being shoved onto tracks during a drunken fight. A down-on-his-luck construction worker survived a 625-volt zap to the head after getting pushed onto an electrified third rail during a drunken brawl in Brooklyn.

What is the biggest scale model train?

In Hamburg, Germany, housed in a nondescript brick building, youll find the Miniatur Wunderland – the largest HO scale model railroad in the world.

What happens if you pee on the third rail?

Penile electrocution is very painful. And if the electrical current is sustained, your testicles will explode. There have been plenty of reports of death while peeing, but few have confirmed that the pee-to-rail contact was the actual cause of death, rather than electrocution for touching a 600-plus-volt line.

Has anyone ever survived the 3rd rail?

Andy Morris hit an electrified third rail after being shoved onto tracks during a drunken fight. A down-on-his-luck construction worker survived a 625-volt zap to the head after getting pushed onto an electrified third rail during a drunken brawl in Brooklyn.

Can you pee on the third rail?

The stream of urine had come into contact with the 600 volts of the third rail. Because the fence is higher off the ground than a train track is, urine wont have time to separate into droplets, and the current can travel up the stream.
