What is the difference between train from subway? specifically in europe?

Question

what's better to take?

Answer 1

In European cities the underground and surface rail systems are integrated and there are frequent interchanges, as e.g. in London where all the major Network Rail terminus stations and other important stations are linked by the Underground.

Tickets are also usually arranged so that you can pay one fare and use it on any kind of transport over the route. So for instance in London, a ticket between two stations on the Network Rail system that involves changing between two terminus stations will also include the fare on the Underground line connecting those stations.

Check out Berlin, where connections between the eastern and western halves of the city have improved since reunification, e.g. a lot of U-Bahn (underground) and S-Bahn (suburban) rail stations that were closed when the Wall was built have reopened since it came down.

Answer 2

A train is above  ground and the subway as you call it, but it is called the underground in Europe and is self explanatory.

Answer 3

A subway/underground(england)/Metro is a metropolitan light rail for the mass transport of passengers in a metropolitan area.

A train gives you - besides to short distances in suburb traffic - long distance connections between towns for both passencers and cargo (freight). Hope this helps a bit.

Answer 4

Your supplemental question doesn't really make sense. It's not a question of which it is better to take but which will take you to your destination. In inner London, for example, you wouldn't take anything other than 'the subway' In some areas, however, you have the alternative of taking a 'train' or a 'subway train' - for example if you were travelling to Harrow-on-the-Hill, you could get a fast train from London Marylebone on the Chiltern services, or a fast subway train on London Underground's Metropolitan Line. If, however, you were going to the station before, Northwick Park, you could only use the 'subway'. So there really is no 'better'

Incidentally, if you are travelling across London from one main line station to another, don't assume that your ticket will cover you for travel on the Underground as one answer implies. It must ensure when booking that it will be endorsed to that effect.
