The Bay Area Garden Railroad Society's waist high track features live steam
locomotives. These railroad engines are designed to be run in anybody's
backyard garden. Live steam locomotives have a butane fueled fire that
boils water. The resultant steam is then used to power the pistons. This
is the same technique full sized locomotives have used for 175 years. Many
examples of old time model steam locomotives will be seen running on the
track, all the while puffing wonderful plumes of steam.
