Minecraft wiki entry for Train_station, associated text: The above video is a slight variation that of the first design, that uses lava instead along with pistons is available and does not rely on any glitches, thus is considered to be safe for use in the latest versions of Minecraft (1.6+). When the player arrives in a minecart, the minecart gets broken by the lava and collected by the hoppers while the player is pushed out of the exit using a glass block connected to a sticky piston. While slightly more redstone intensive than Sethbling's design (which was exceptionally simple), it does not have any problems associated with it and is thus recommended for anyone playing in 1.6+. If you are playing in Java Edition 1.5.2 or below (and not planning on updating), Sethbling's design is definitely better.
