Are you intending to make it a openBVE exrerior, or just another
object?
He meant, an exterior case, which can be used as a train (Used
to drive it actually, which there are many aspect that Google
Sketchup does not do such as motor sounds etc), or another still
object, that can let the route developers put it, and assume that
is another train on other platforms, in order to look real (How can
an entire stretch route, got only 1 train, the frequency sure
sucks).
