For anyone that wants to build a station for the main lines i have posted a video here: http://www.youtube.com/watch?v=C4RjxkK0QeE (watch out, some music kicks in after a minute and there have been some alterations made since then) A main line station will have 2 station parts, one for each direction. You do not have to include the wool - the launch <direction> sign fixes that. Have a quick look at the station directly below you as you enter the pantheon.
Obviously we dont want too many mainline stations along each NESW direction so would be cool if people could poke their neighbours and get a local one up (with substations for your homes if needed). Thanks!
-This is for all directions not just North btw
you don't need the second button either now, you can have a "launch player" sign.
when th cart is summoned it sits on the obsidian launcher and when aplayer gets in it auto lunches them.
