Tutorials/Water tram

The Water Tram (Nicknamed "EATS Road" by its creator) is a fast travel creation which only requires water, a boat, and pressure plates. It was originally created by Etho, who masterminded this wondrous creation. Later improved and updated by people such as Random2251. It was created as a resource-wise version of a tram. A water tram can involve a complex delivery system, where you get a fresh boat every time you go there, or it can be as simple as a 2x3 tunnel. But a water tram absolutely requires pressure plates. Otherwise, it will just be a water tunnel, and while you can reach high speeds with it, you cannot get a massive burst of speed. But here is where the water trams special system comes in.

The water tram relies on water currents to get it at a high speed, but since water only goes eight blocks, you need multiple water currents. But, if you just place random water sources at random intervals, you will go into a current going backwards from where you want to go, so you don't get anywhere, at least on the boat. Or very slowly. However, pressure plates cannot have water going over them, like ladders and signs, so this is a key part.

What you do is make an infinite water spring, which you can easily do with 2 buckets of water. Then, you fill your buckets with water, and set off. You build your tram road so it is two blocks wide for the water part. Then, you put two water sources at one end, let it flow for several blocks, then place two pressure plates to stop the flow. Then, you place two water blocks after the pressure plates, make sure to keep it exactly after, and do it again, and again, until you can cross great distances at ease. The best setup is to have 5 water blocks per section (1 source + 4 flowing); any more than that and your boat will hit the side of a pressure plate and break. It's also the fastest, travelling at about 7.7 blocks per second (192 blocks in 25 seconds) - 35% faster than sprinting, and without the hunger drain. If signs are used instead of pressure plates, sections can have up to 7 water blocks, but this does not significantly increase speed, and requires more resources. Making the sides of the road out of pressure plates as well is recommended; boats will break if they hit full or half blocks.

Making two parallel roads in opposite directions allows easy two-way transportation. The pressure plates can be connected to redstone circuitry and act as motion sensors.

With an appropriate mod installed, the same technique can be used with lava and minecarts. However, it isn't much faster than walking, even in the Nether, and neither as safe.
