This means that extra engines only make sense if they weigh much less than the total weight of the train, otherwise they are a waste of money.

	Another small benefit of additional engines is that they increase the maximum speed slightly, because there is some excess power available to accelerate the train to a higher speed. ~~ ~~The first additional engine adds 20%, the next one 10%, and a third extra engines add another 5%. ~~ ~~After that adding more engines will not ~~ ~~increase the speed any more. ~~ ~~The amount of this increase (in percent) is an option to the switch, the default is 35% in total. ~~ ~~If you want the game to be more realistic, you should probably disable the speed increase using multihead 0. ~~ ~~Otherwise, the parameter can be anything between 0 and 100, in which case the additional engines add 4/7, 2/7 and 1/7 of that amount, respectively.

Buy additional engines for a train.

-=Switch=-

Configuration file: multihead [<speedup>]

Command line: -M

-=Quick Info=-

The multihead switch lets you add additional locomotives to a train by holding the control (ctrl) button when clicking "Build Vehicle" in the purchase list.  Each locomotive adds its power and tractive effort to the train. The top speed of the train is that of the slowest engine plus up to the given <speedup> percentage.  If no value is specified, a value of 35% is used, however zero is a more realistic value.

The first additional engine adds 4/7 of the specified speedup to the speed of the slowest engine.  That means that one additional locomotive would add (4/7 * 35)% to the maximum speed of the train, or 20%.  The next adds 2/7, which would be 10%, and the last adds 1/7, or 5% to the top speed.  For this reason, multiples of 7 are recommended for this switch's value.
