多车头可以给火车提供更高的载货能力和马力。它可以让火车爬坡，加速更有力，可以带动更多车厢的货物。

当你打开了“多车头”开关，火车头就被看作是像车厢一样了。由此火车头可以被挂接在（在车库鼠标拖动就可）另一台火车头的后面。多车头火车它的最高速度取决于它所有车头中速度最慢的那个，不过该火车的马力是所有车头之和。

（第三段，不清楚再说什么）

有些车头本身就是多车头了，比如Asiastar 和T.I.M. ，他们每个车头其实算作2节，一个头一个尾。这一个头一个尾它们都有着相同的速度，但是马力分别只有整个车头的一半。不过只有“头”（方向朝左的那个）可以用来创建整列火车，“尾”只是一个提供动力的车厢罢了，且“尾”必须跟在一台有编号的火车后面（一列火车有了编号才算在游戏里存在）。

英文原文:

Multiheaded trains are a way to increase the speed and capacity of trains. Multiple engines are added to the same train to allow better climbing of hills, acceleration, and greater capacity for cargo

With the "Multiheaded Trains" patch turned on, train engines are treated as cars and can be moved from one train entity to another. Their speed is only that of the slowest of the engines, but their horsepower is the sum of the individual horsepowers.

Note that this differs from TTDPatch Multihead handling in several ways: You no-longer have to create the engine as a train car by holding ctrl. Instead you simply drag the second engine onto the train it will join. Also, second engines can only subtract from the total speed, not add to it.

Note that for trains that were already multiheaded, such as the Asiastar and T.I.M. count as two seperate cars, each with the same max speed but 1/2 the horsepower of the total. Only the first head can be used to create a route, the second is only a car and must be attached to another train entity.
