Minecart Tracks (or Rails) are Non Solid blocks first seen in the First "Seecret Friday Update" to Infdev. The block, like other Non Solid blocks, has 1 sprite and appears as a 2D image in the players hand. Tracks do not appear anywhere on a natural map. For now, tracks can only be crafted in Infdev and Alpha mode.
A Track's purpose is to provide a line where Minecarts can move across easily.
Crafting
16 track pieces can be crafted from 6 Iron Ingots and 1 Stick, in the pattern below:

Behavior
Tracks next to one another will attach to each other automatically. If two perpendicular track pieces meet, the track connecting them will turn into a curve.
If a track leads up to a 1 block high ledge, the piece placed up against the ledge will turn into a ramp if another track is placed on top of the ledge.
Redstone Torches, Stone Buttons, Levers and Pressure Plates will change the direction of a curved track piece. Since there is no cross section track, this is how the player must have a track system that leads in more than 1 one direction. In rare cases, curved track sections will not change appearance when their direction is changed. If a track switching mechanism seems to be inexplicably broken, test it by running a cart on the track rather than by looking at how the track appears to be oriented. Electricity will not affect normal track blocks or track ramps.
If a straight track piece leads to a curve block and isn't attached to the curve, a Minecart will run over the gap and continue to go straight over the curve.
At 'T' intersections, trains will always travel south or west, as shown in the below diagram:
If water flows against a track, it will remove it and drop the track as a resource, similar to Torches.
