Metros and Subways

They are tickes purchased during the off-peak tourist season and also tickets purchased after 9:30 a.m. rush hour.

Tickets for Underground, buses, the Dockland Light Railways and other forms of mass transit in London can be bought at machines in any Underground station, at certain bus stops, London Overground stations, most National Rail stations and the London airports, as well as, using cash, on board most London buses.

Beyond this, London has, more and more, moved toward a 'smart' card called an Oyster card. This card can be purchased from any Oyster Ticket Shop, found in hundreds of shops, newsagents and off-licenses all over London.

Oyster cards can be either set up with a Pay-As-You-Go credit amount, or used in a Travelcard setting, where-in you set an amount of time, and a number of zones, and are then free to travel within this set limit.

Either type of usage is valid on all forms of mass transit in the Greater London area, and are notably cheaper than paying cash for your travels.

By underground (tube).

Generally, no it isn't. However, some individuals might think it is scary, like if they did not like being underground or have some other phobias.

The G train (the light green line). It runs through Brooklyn and Queens only.

It is called the because of it's shape. If you look at the Paris Underground it is square but the London Underground has tube shaped tunnels and stations. Even the trains are tube shaped, apart from the lines which go overground for quite a way like the District and Circle line.

Fulgence Bienvenüe, a French civil engineer, and Edmond Huet, a engineer and director of the Paris civil works, coauthored the project of the Parisian métro. (links)

The modern London Underground schematic map was designed by Harry Beck in 1933.

Henry Charles Beck (Harry Beck), invented the iconic, topological London Underground map in 1931 while working as a draughtsman for London Underground. It was a spare time project and not part of his job description.

I don't think any metro stations in Madrid do.. I had to carry 4 months of luggage on the Metro.. Lets just ssay i didnt make it alone, and ended up getting help from some toothless guy..

When tunnel boring machines came into usethey used some of it to mix with clay slurry to create the solid walls. Some may be left as is as an earth pressure balance shield. As for the rest, landfill is the most common, they also recycle parts of the soil makeup like the silica and minerals but where you ask.... hmmm, this is stumping me.......

The nearest underground station is Tower Hill - on the District or Circle line. The Tower is a five-minute walk, and is well signposted. Last admission is 16:00.

Subways are also called 'theUnderground' ...

In New York City they're Subways, but in London, they are The Underground.

That line is the most central line and is called the Circle Line.Operating round the central of London it's a surprise it isn't called the Central Line.But there is a Central Line, and a section of it runs just north of Westminster.

The basic Métro ticket is a small piece of cardboard with a magnetic strip that costs €1,40. It's issued by RATP, the transportation authority for the Paris region. You can save money by purchasing a carnet of 10 tickets for €10,50 at the ticket window of any Métro station or from vending machines near the turnstiles. Ask for "une billet, s'il vous plait" or "un carnet, s'il vous plait." (A carnet is simply a stack of individual tickets that you can share with family or friends.)

A single ticket will take you anywhere within the city of Paris on the Métro and RER networks, and you can transfer between lines--or between the Métro and the RER--on the same ticket. You can also use tickets from your carnet on public buses, although transfers between the rail and bus networks aren't allowed.

If you plan to use public transportation extensively, you can save even more money with these special passes:

Mobilis, a pass for one calendar day. The price depends on the zones where you intend to travel; if you plan to stay within the city, a Zone 1 pass is all you need.

Paris Visite, a tourist pass valid for one, two, three, or five calendar days. Again, the price depends on how many zones you need. Children from 4 to 11 pay half-price (kids 4 and under are free), and the card offers discounts on boat cruises and certain other tourist attractions.

The Carte Orange, which requires a passport photo, is used mostly by locals. The weekly or carte hebdomadaire pass runs from Monday to Sunday, and the monthly or carte mensuelle pass is good for one calendar month.

Other passes are available for residents (including students at universities and other schools in the Paris region).

Where to buy passes: You can buy Mobilis, Paris Visite, and Carte Orange at major Métro stations, RER stations, and railroad stations in the Ile-de-France region, including those at Paris airports. Paris Visite is also available at branches of the Paris tourist office and from our partner, Rail Europe, which also sells the Paris Museum Pass.

Tips:

*

Paris is a city that's best enjoyed on foot, so a carnet of 10 tickets is likely to be your best value unless you have limited mobility, are pressed for time, or are staying a long way from tourist attractions.

*

Don't be surprised if your US credit card doesn't work in Métro or RER ticket machines that are designed to work with European "smart cards" that have embedded chips. If your card doesn't work, just go to the ticket window.

Underground railways are known, in the USA, as the subway.

The trains have electric heaters that are used on outdoor sections in cold weather. Some outdoor stations have heated waiting rooms on the platforms. The tunnels and underground stations are heated by the heat given off by electrical equipment and by the trains and passengers that pass through. No additional heating is needed and the deeper sections need cooling, especially in summer,

The tunnel between East Finchley and Morden (via Bank) is the Underground's longest and one of the longest rail tunnels in the world, 27.8km (17.25 miles). However, Morden is covered by a canopy and is therefore tru to your question but East Finchley is not. The previous station to East Finchley is Highgate, approximately 1200 metres from East Finchley.

The London bombing did occur in central London. The attack targeted the London Underground.

The trains are powered by electric motors. Electricity is provided to the trains via the third rail, an electrified rail which runs along the tracks parallell to the "running rails" (which actually guide the train) and the trains have runners which transmit the electricity to their motors inside.

Whereas mainline railways tend to have one third rail, the London Underground actually has two.
