+Minecart=トロッコ
+Minecarts can be used for a quick transportion on rails.=トロッコは、レールを使った高速輸送を可能にします。
+Minecarts only ride on rails and always follow the tracks. At a T-junction with no straight way ahead, they turn left. The speed is affected by the rail type.=トロッコはレール上にしか乗らない為、常に線路に沿って走ります。直進できない丁字路では、取り敢えず左折します。速度はレールの種類によって異なります。
+You can place the minecart on rails. Right-click it to enter it. Punch it to get it moving.=レールの上にトロッコを置けます。右クリックで乗り込みます。パンチすると動き出します。
+To obtain the minecart, punch it while holding down the sneak key.=トロッコを入手するには、スニークキーを押しながらパンチします。
+A minecart with TNT is an explosive vehicle that travels on rail.=TNT付きトロッコは、レール上を行きかう爆薬車両です。
+Place it on rails. Punch it to move it. The TNT is ignited with a flint and steel or when the minecart is on an powered activator rail.=レール上に配置。パンチで移動。TNTが着火するのは、火打石と打金を使った時か、稼動中のアクティベーターレール上にトロッコが乗った時です。
+To obtain the minecart and TNT, punch them while holding down the sneak key. You can't do this if the TNT was ignited.=トロッコとTNTを入手するには、スニークキーを押しながらパンチしてください。TNTに火が着いていた場合は、無理です。
+A minecart with furnace is a vehicle that travels on rails. It can propel itself with fuel.=かまど付きトロッコは、レール上を走行する車両です。燃料で自走できます。
+Place it on rails. If you give it some coal, the furnace will start burning for a long time and the minecart will be able to move itself. Punch it to get it moving.=レールの上に置きます。石炭を与えると、かまどが長時間燃え続け、トロッコが自走可能になります。パンチすると動き出します。
+To obtain the minecart and furnace, punch them while holding down the sneak key.=トロッコとかまどを入手するには、スニークキーを押しながらパンチします。
+Minecart with Chest=チェスト付きトロッコ
+Minecart with Furnace=かまど付きトロッコ
+Minecart with Command Block=コマンドブロック付きトロッコ
+Minecart with Hopper=ホッパー付きトロッコ
+Minecart with TNT=TNT付きトロッコ
+Place them on the ground to build your railway, the rails will automatically connect to each other and will turn into curves, T-junctions, crossings and slopes as needed.=地面に置いて線路を作ると、レール同士が自動的につながり、必要に応じてカーブや丁字路、踏切、坂道などに変化します。
+Rail=レール
+Rails can be used to build transport tracks for minecarts. Normal rails slightly slow down minecarts due to friction.=レールを利用して、トロッコの輸送路が敷けます。普通のレールは、摩擦の関係でトロッコが少しずつ減速していきます。
+Powered Rail=パワードレール
+Rails can be used to build transport tracks for minecarts. Powered rails are able to accelerate and brake minecarts.=レールを利用して、トロッコの輸送路が敷けます。パワードレールは、トロッコを加速させたり、ブレーキをかけたりできます。
+Without redstone power, the rail will brake minecarts. To make this rail accelerate minecarts, power it with redstone power.=レッドストーン動力なしだと、このレールはトロッコにブレーキをかけます。このレールでトロッコを加速させるには、レッドストーン動力を供給してください。
+Activator Rail=アクティベーターレール
+Rails can be used to build transport tracks for minecarts. Activator rails are used to activate special minecarts.=レールを利用して、トロッコの輸送路が敷けます。アクティベーターレールは、特殊なトロッコを作動させるために使われます。
+To make this rail activate minecarts, power it with redstone power and send a minecart over this piece of rail.=このレールでトロッコを作動させるには、レッドストーン動力を与えたレール上にトロッコを送り込みます。
+Detector Rail=
+Rails can be used to build transport tracks for minecarts. A detector rail is able to detect a minecart above it and powers redstone mechanisms.=レールを利用して、トロッコの輸送路が敷けます。ディテクターレールは、その上にあるトロッコを検知でき、その際レッドストーン機構の動力源となります。
+To detect a minecart and provide redstone power, connect it to redstone trails or redstone mechanisms and send any minecart over the rail.=トロッコを検知してレッドストーン動力を供給するには、レッドストーン導線またはレッドストーン機構に接続し、任意のトロッコをレール上に送り込みます。
+Track for minecarts=トロッコ用の線路
+Speed up when powered, slow down when not powered=稼動中は加速、非稼動中は減速
+Activates minecarts when powered=稼動中はトロッコを作動
+Emits redstone power when a minecart is detected=トロッコを検知するとレッドストーン動力を放出
+Vehicle for fast travel on rails=レール上を快速移動するための車両
+Can be ignited by tools or powered activator rail=道具や稼動中のアクティベーターレールにより着火が可能
+Sneak to dismount=スニークで降りる
