I just did a quick run through and cleared a jam or too and checked minecart inventories. Heres some general rules to keeping the system running if I'm not around
* Clear jams. Jams create mroe jams. The sooner you track down a rogue cart, the better. Even destroying the cart is fine. I carry a lighter for cart disposal, though you have to break the track near it to start the fire.
* Be aware of how the cart inventory system works. Each 2 way route has a chest at each side. These chests should optimally contain a single line/line and a half of carts. If less, please make more carts (or just dupe em in the chest, like I do) and if its more than a line and a half, take some out. The nature of how we can teleport means theres going to be some bias in what chests get what and the distribution is not necessarily going to be even. If a station doesn't have cart waiting, its probably out of carts. I might add a double chest to all of the service rooms for storing excess/spare carts. You shouldn't have to do this very often, but its good to keep an eye on it.
* You can still somtimes get nailed by dead zones (the kind that make ghosts) if you're impatiant. It happened to me today. I logged in and spawned all the way on the floating islands then went all the way to Detonation Station, where I hit an unloaded area just before the exit. If you just logged in, wait a bit for things to load between each station. If I waited a bit longer, the station would have been fully loaded. Also remember, DO NOT EXIT THE GAME UNTIL YOU HAVE TELEPORTED SOMEWHERE. This shouldn't happen much with how the tracks are designed, but if it does /warp or /spawn and then I advise to take the time to walk to where you got ghosted. The chunk will refuse to load, so don't walk into it. Once you get that, log out and log back in. You should be falling in the void. Then when you /spawn there shouldn't be a ghost.
Actually as a general rule, NEVER EXIT THE GAME IN A CART (if you get disconnected because you accidently road a cart into a treasure chest, don't worry, that never makes ghosts). If you get stuck ever, teleport somewhere safe and then turn off the game.
Anyways I'd be interested in hearing what destinations people would like to see trains too.
