Heh, never mind...turns out "horse train" is the default, and the tracks for a horse train are identical to those for a steam engine.

Seriously, anyone use a horse train when steam is available?

[hectobar]

yes, Becasue they are a lot more powerfull at the begining of the game. When Steam engines cannot use multiple traction.
