* Prologue
I always forget how to build these things. So might as well write it
down.

The idea of a refit station is to not clog up your network with empty
trains. A train delivers one cargo at the station, enters a depot,
refits to a different cargo and then enters the station to pick up the
new cargo.

To prevent trains from piling up in the depots we need to add some
fancy signalling. On the way in we use a one-way entry-signal, and a
one-way combo-signal. On the way out we use a one-way exit-signal. To
make the depot available as soon as the leaving train is on the
loading platform we need to add a path-signal after the exit-signal.

By staggering the station by two tiles we can build the traditional
diagonal ro-ro station and have the correct amount of breaking space
in front of it.

* Refit Yard
To refit trains outside of a station a refit-yard can be used.
