After a month of waiting, the granite ballast finally went in today!
A crew of five spent the day with shovels and wheelbarrows putting
down the ballast between the wooden ties and
levelling the backyard dirt around it. The kids and I got home just
as they were finishing. A supervisor is out there
now making things pretty. John is up at the
JavaOne Conference
in San Francisco’s Moscone Center, so we will have to wait for
tonight for him to see it.

When I called John to tell him about the ballast finally going
in, he had to make our conversation short. The
JMRI open
source model railroad interface software he has been working on
just won the
Duke’s Choice Award in the “Java Everywhere” category.
John had to go up to the Moscone stage with team leader
Bob Jacobsen. As the web page says, Duke’s Choice “awards spotlight
some of the most clever, practical, and inspirational Java technology
applications on the planet.”

It has been an exciting and busy day.

The team preparing the
JavaOne Conference display on
JMRI open source model railroad interface software and
Turtle open source model
train circuit boards met for the final work day at our house in San Jose
on Saturday. Photos are below.

The layout went to San Francisco on top of our truck
yesterday and is installed (and working) at Moscone Center. John
is designing and printing out paper documentation now…

The supervisor from the construction company came by this morning
to look at the site (our backyard) before starting the final phase of
soil and gravel moving. The 45 foot rail line is installed except for
the ballast:

The supervisor was going to put in the gravel today using a crew with
shovels and a wheelbarrow but once he saw the site, he decided to come
back with a Bobcat. John talked with him to be sure that the ballast
will be granite rather than serpentine rock. Serpentine is a natural
source for asbestos and we don’t want that kind of trouble in our
backyard. Work should start tomorrow (or Monday at the latest). The gravel
will come from the same local quarry supplying ballast for San Jose’s
light rail line.

John is almost done preparing the package of materials requested by San Jose
city hall so that we can formally start the special permit process to
install our caboose. We check on WP668 every day and she is still
patiently waiting for her final trip by truck and crane to our backyard.

The team preparing the
JavaOne Conference display on
JMRI open source model railroad interface software and
Turtle open source model
train circuit boards met again at our house in San Jose yesterday.
My husband John had put in time in advance putting down “grass”
(different colors of shredded foam) and ballast around the tracks for
basic scenery. John also built a stand for the layout to sit on.
He and Bob and Jon and Dave spent yesterday programming and
wiring and testing the little layout.

There may be time for one more work session before the layout goes to
San Francisco’s Moscone Center on Sunday. The
JavaOne Conference
opens 16 May 2006.

My husband invited a group of fellow model railroad enthusiasts
(aka “train nuts”) down to our San Jose home yesterday to build
a small, portable, HO-scale model rail line to demonstrate JMRI
software at next week’s
JavaOne Conference.

JMRI
model railroad interface software controls model trains
and layout accessories such as turnouts or switches, animation,
locomotive speed and direction, and sound. Bob and John and Jon have
been working on JMRI open source with several hundred people all over
the world for many years. John has also been creating open source
model train circuit boards
to interface with JMRI. Yesterday’s group was made up of
those who were available to come to San Jose.

From about ten years’ experience observing and participating in this
obsession (ahem, that is, hobby), model railroaders usually focus on one
of three major categories of passion:

• Modelling (the scenery, houses, equipment casings, etc.)
• Operations (running trains on a model layout with timing and
  behavior as much as possible like a real or “prototype” railroad)

• Computers (the hardware and software that run the trains and the layout)

Yesterday’s group (John, Bob, Jon, and Bob’s son Bear) are definitely
computer-focussed. I think they will
probably get around to adding some ballast, grass, and maybe a tree or
two, but the fun is in the equipment itself. John got the wooden frame
ready in advance. He and the rest worked for about 5 hours yesterday
and left off when they could run a model engine around the loop without
incident.

Yesterday was a bright warm day and the favored task was
anything that involved laying on the warm asphalt of the driveway
in the shade of the layout itself. The first job was to paint the silver
coating of the layout base so it would not blind the workers…

We meet again in a few days to finish up (and maybe add a little bit
of scenery). Next weekend, we will take the little layout to the Moscone
center for installation in preparation for
JavaOne.

John took the most recent photos off of one of the digital cameras
so below are images of building a 45 foot rail line in our
backyard. We are still waiting for the ballast delivery and
installation – we had hoped it would be this week. John talked with
San Jose city hall again and, after looking into several creative
alternatives, it looks like we will need a special
use permit after all to install the caboose itself.
