Minecarts "bounce" off of obstructions on the track.A long stretch of rail or an up-slope reduces a cart's momentum and thus its speed, eventually stopping it unless the forward key is held throughout by a player riding the cart.

A stretch of an unactivated powered rail of at least two blocks length brings a loaded cart at full speed to a complete halt.A player riding in a cart may add momentum by "pushing" it using the forward control.A minecart with a player inside goes from stationary to full speed after about 13m of powered rail.Activated powered rails, down slopes, and being pushed by players or mobs add momentum to a cart, increasing its speed.A chest minecart carrying 320 items (5 stacks) travels 101m from full speed.An empty hopper or chest minecart travels 165m from full speed.A fully loaded hopper or chest minecart travels 40m from full speed.A minecart with a player inside travels 309m from full speed, staying at full speed for 176m.Minecarts move differently depending on their load.On a diagonal track they move at 11.314 m/s = sqrt(2) * 8. Minecarts move at 8 m/s at top speed on a straight track.The following are the most important properties of minecarts. 4.1.3 "Whirligig" cyclical minecart accelerator.By double tapping on the map, you can quickly enable/disable the functionality as well.

With that option enabled, you can drag the map with your finger to navigate, you can pinch to zoom in and out, and you can tap and hold to set a marker on the map. When using a touch-enabled device, an extra option for enabling/disabling touchscreen control will appear below the map. The "Save Map" button allows you to save the currently shown map as png image file. You can always remove and add the marker by double clicking on the map. The lower inputs allow you to go to a specific point (e.g., your base) of the map and set a marker there. You can use the slider below the map or your mousewheel for zooming. To scroll, use your arrow keys while your mouse cursor points at the map, or move your mouse while holding down the left mouse button. Once you entered your seed and version you can start using the map. The app does this the same way Minecraft does, so it's safe to use letters (and other characters) as well. If you type in anything else (like letters), it will be converted to a number. You should also know that a seed is always a number (up to around 20 digits).

When loading a seed from a level, the seed will automatically be stored as a level. Levels allow you to store and reuse seeds on this website, without having to load your savegame every time.
POWERED RAILS MINECRAFT WIKI WINDOWS
On Windows you can use %appdata%\.minecraft\saves to get to that folder. You can find the savegames in the saves folder of your Minecraft installation. Level.dat is a small file located in the folder of every Minecraft savegame. The latter can be done by clicking on "Load from Save." and selecting your level.dat, or by drag&dropping the level.dat file into your browser window. You can either type it in manually, or you can load it from your savegame. The first thing you should do is select a seed and version.
