My new phone...and the Seoul subway

I recently got myself a mobile phone. It has all kinds of completely useless features that I'll probably never use but it also has a really cool feature. It has details of the subway. As you can see from the photo it has a subway map on it so you can plan your route but it also has details of all stations. The best bit is that it tells you exactly which part of the train you need to stand in for transferring from one line to the other. Think about how many times have you thought you needed to be at the front of the train to change lines only to realise that actually you need to be right at the back. The subway here is really good. It costs about 45p per ride and you can transfer to a bus for free when you come back above ground. It is also very extensive having ten lines with more under construction. You can see on Wikipedia how it compares to other systems in terms of length, number of passengers and number of stations. Mind you the figures quote for length and number of stations don't include all the items on the map as some stations are counted as being train stations and are therefore excluded even though they are serviced by subway trains and require no seperate ticket. If you include those stations then there are 389 stations in total. Line number one runs from north eastern Seoul to South Western Seoul and is 143km long and takes more than three hours to go from one end to another. Cost of that journey? 1 pound 50p.
