The lines have different colors and this way it is very easy to figure out which one you need. There are a green, purple, blue and light blue, red, orange and yellow, and grey lines and there is also a radial brown line that kind of shows the limits of the city center. The trains run very often and you can see on the tableau in the front how long it has been since the last train. You don't need to pay for the transfer to another line anywhere. The names of the stations have also become a reflection of the time they were built. They used to carry names of Karl Marx and the revolution - now many were renamed, and if you haven't been in Moscow for a while be prepared: most of the stations in the city center now have different names. So find the most current map of Moscow metro and study before you go.
