Jeff, James, and Alvar worked on wiring design and documentation for the
control of switches. The layout switches are now fully documented, making
the installation of the switch cards much more easier.
John P worked on adding "corrugated tin" roofing to the produce
warehouse and also improved some P-yard switches. John M paint-matched
the floor in another extended section of roundhouse flooring.

The Building 20 Presentation is back online in the

John P. and Jeff continued to work on the interface between the PC and
System 2 in order to enable call-on directly from the PC. This will allow
us to have one single 'dispatcher' terminal again! Dick Lord put together
the boards necessary to create 'X1', 'X2', and 'X3' swing blocks, which
completes the electronics necessary for swing blocks for phase one.
Bill Onorato continued his work on the vegetable oil facility at the
East end of Gifford City. He also brought in many sheets of brick and
stone material to work on scenery! Alvar did a lot of work in the new section
of Gifford City. He installed all the roadbed, both for the trolley line
and the sidewalk, all the way to the main passenger station. Also, he
began to work on the bridge to 105th street, and the pedestrian tunnel

John P. and Jeff worked on the assignment system, which is making excellent
progress. The new assignment control allows the PC controlled
microprocessor system to do cab assignments with System 2. This design
completely eliminates the need for the PDP 11-based "S-board", which has
been decomissioned as of today. Jeff also did some System debugging- or better
Alvar built a covered cable trough to convey control and power wiring from
the new electronic switch-throwing system and the new power supply to
System 2 and the tower (signal and power distribution centers, respectively).
He also installed a 'power-on' LED directly at the new power supply, to
easily see when power is on.
John M installed another replacement section in the roundhouse floor. Now
that test painting has been completed, final painting will occur when all
the sections are in place. Andy Miller performed coupler re-alignment and
other corrective surgery on the Aaron Burr cars.

Andy began to paint the stone walls that go all around the old sections
of Gifford City. He used a technique that gives the stones a light
background and a dark foreground. John Purbrick continued work on his
produce plant, now that there is enough brick material!
Alvar prepared the wires for the next switch card. John Shriver first
transfered the center lines to the roadbed that Alvar placed down one
week ago, and then began installation of girder rail for the trolley
line. After some tests he said : "It will lay MUCH faster than the old way,
that's certain." Jeff and James continued work on System 2, doing
more and more de-dusting.
- November 18
Now that computerized assignment, computerized switch-throwing, and The
System are all operational, various layout wiring and block gap problems
are more evident. Jeff and James did some trouble-shooting on the layout
wiring and block gaps to deal with these problems. John M extended the
flooring in another roundhouse stall. John P prepared another section of
brick wall for the produce warehouse.
- November 21
Bill and John P continued to work on their respective buildings
(the vegetable oil distributor and the terminal, both on the east of Gifford City). John McNamara worked on the round house- he has
only two more bays to go before finishing the floor additions
(painting is next).
You'll soon see a big update of the Progress Gallery.
Jeff, James, and Alvar worked on installing the last three switch cards.
At 5:00am Jeff and Alvar called it quits, after fully installing #5,
doing 70% of #4, and 40% of #6. This means that with one more session
all the cards should be in! And, finally, the great news: John P brought
in a new version of this Sys3 program that allows GRAPHIC SWITCH THROWING. That is, by 'clicking' on a switch in the monitor, the switch changes
on the layout! The next and final part for a 'beta release' of the system is to integrate assignment...
On Sunday Nov 15th an article on Model Rail Roads around the Boston area
appeared in the
We have a copy of the article for you
Also, today, James and Alvar both brought in digital cameras, and took lots of pictures of the layout (over 50 of them!). These were added to a Progress Gallery which they
added to the web-site. This gallery contains many pictures of the layout
as it grows from the ground up.
Finally, the links page has been added links of web-pages of club members.

Bill continued work on his vegetable oil facility. Alvar finished
wiring all the Switch Cards, and ran power to the last three. John P.
installed a new version of the graphical interface which allows both
assignments and switch throwing.
