The performance of a rail line is affected by the way the track is placed. Running track next to a wall, placing lampposts next to it, or having hills to climb will adversely affect the speed of a cart, and so its distance traveled.
A distance trial track was constructed to see how far different carts would travel, with and without loads. When darkness set in a number of lamps were placed on blocks set next to the track so that observations would remain accurate, but the distance achieved in all cases fell to a fraction of what it had been. For instance a player riding in a cart could reach the end of a 250 block long rail line before the lamp posts were installed, but could only reach block 187 with them in place. While trying to understand the reasons for the change, the testing surface was cleared down to the white floor and the distances traveled returned to their previous, much longer, values. To confirm the slowdown was caused by interaction with the blocks next to the track, a wall was placed along it. The distance traveled again fell to 187 blocks, as marked by the 红色砂石 column in the images. [需要验证]

Some Youtube videos suggested that diagonal track might offer better performance than straight runs. This has not proven to be the case .. another distance trial track was constructed with a length of 300 blocks. Carts with no rider travel the same distance as on the straight track, about 18 blocks before they stop, and a cart with a player riding can make it to the end of the track. The interaction with blocks next to the track seems to be a little stronger with carts on diagonal track. With lampposts placed only every 10 blocks along the track an unmanned cart could only cover 12 blocks, and with a player riding just over 180 blocks, a significant reduction.
What the tests have confirmed is the increase in speed. On each curved track a cart effectively moves 2 blocks, thus its maximum speed is 11.314 m/s, an improvement over the maximum of 8 m/s on a straight track.
上坡铁轨
A minecart with no rider, at full speed can climb 10 blocks on unpowered, upward sloping rail. This suggests that powered track is only needed at this height to keep a cart climbing. However, the cart slows so much that it can only reach another 5 blocks high with 2 lengths of powered track starting at 9 blocks high. Further testing showed the minimum number of powered blocks to keep the cart climbing well is 3 powered rails every 6 blocks starting at 9 blocks high, at the cost of a strong reduction in speed. To maintain speed in a climb a ratio of 5:4, powered versus regular rail segments, is a good compromise for decent speed at a reasonable cost, starting with 2 powered rails on the flat before the upward slope to be sure the cart starts the climb at maximum speed.
If construction cost is no object one can of course use powered rails all the way to the top to get the best possible performance.
Carts with a rider, or chest carts, have more momentum and so climb higher than one that is unloaded. With a rider a cart can climb at least 24 blocks before needed powered rails to go higher.
The time to travel the full 2 km length is different for all the other minecart type, requiring more powered rails to reach the top speed of 8 m/s. The following table lists the data collected: [3]. Note that the optimal rail spacing for a fully loaded cart differs, see the original reference for details.
最佳的利用方式需要将矿车的运动和充能铁轨的放置进行同步;将一个充能铁轨沿着线路向前或后移动一格会产生显著的影响。这是因为矿车的动量是随矿车行驶在充能铁轨之上的每一刻(1/20 秒)增加的 (by 0.9 m/s for occupied carts)。当矿车以8 米/秒的最高速度行驶在笔直的铁轨上时,它驶过每一格铁轨所花费的时间为2或3刻。最佳的放置方式应该保证将充能铁轨放置在矿车花费3刻来驶过的那一格,否则有三分之一的加速将被浪费。
A diagonal track is a track that consists of the pattern 'left corner' attached to a 'right corner' attached to a 'left corner' ... and so on. When minecarts travel on a diagonal track, the camera is held steady in the diagonal direction and the minecart visually travels diagonally along the track as well. The speed limit of minecarts is actually 8 m/s per cardinal axis, thus when traveling on 2D tracks, the cart will travel 8 m/s in both cardinal directions of travel to result in a net vector of about 11.3 m/s or the square root of 128. With a 3D track you travel as fast as 13.85 m/s or the square root of 192.
Because of this difference, there is also a difference between the optimal spacing of powered rails when used on a 2D track when compared to straight travel on flat terrain. This is currently undetermined to high accuracy but is roughly 1 every 52 blocks.[4]
There is also a difference in unmanned or storage mine carts so it is advisable to use a shorter interval if these carts will be used on the track.
It seems as if the optimal Powered Rail placing interval to make storage mine carts move is 4 (1 Powered Rail every 4th block). Compared to shorter intervals the reduction in speed is minimal. The maximal possible interval seems to be 9 as the minecart will not reliably reach its destination when using higher intervals.
使用拉杆来扳动道岔,经过预先设置的一段延迟,充能铁轨被激活。由探测铁轨触发这一延迟。In this design, the lever will always point towards the selected destination regardless of direction.
4条铁路的连接处
多条铁轨的连接处的设计可以是扩展上述的装置。在右边的设计中,乘客有更充裕的时间来选择目的地。玩家先选择左边还是右边,然后选择前边还是后边,就可以选中任意4个目的地。This design doesn't scale well 但是可以做一系列的这种装置,来通往任意数目的目的地。
多目的地选择器
可行的方案有许多许多种,多数是分割成不同单元的设计,这意味着它们可以被扩展以通往更多目的地。经常使用一系列RS或非锁存器来选择目的地 as these latches have a designated reset line (as opposed to a t-flip flop which only has one input).
Example Of A System Incorporating Some of the Basic Parts
This system consist of a "Launcher", a different mechanism for "Empty Carts", a "Junction" and a "Booster"
System works on tripwire.
The empty minecart is always moving in circles awaiting a passenger. (Empty cart compenent is not needed any longer)
When a passenger is present, tripwire will activate and the rails will switch routes for a few seconds and cart will move away from the station. (Launcher, booster and junction all infused into a simple redstone circuit.)
