PEMBROKE
MAKING IT UP AS I GO ALONG
RENE GOURLEY
NOVEMBER 9, 2014
Software development
Q1: WHERE’S
PEMBROKE?
Q2: WHY PEMBROKE?
THE LONG ANSWER…
Canada Atlantic
Railway
1905
Scratchbuilding
Branchline
Pembroke
Proto:87
PROTO:87
Started 1997
Model Railroad Planning
For 10x10 bedroom
Built to move
Problem section joint
In the river
Not tight
Limited operations
Limited information
Based on Goad plan
VERSION 1
Dam is not that high
Bank near station
was not square
THEN THIS…
Uninteresting shoreline
YOU SHOULD
NEVER
INSTALL
VERSION 1
AND I WAS TURNING THAT AGE!
THE SPACE (2011)
Version 1 (for nine years)
Modelling desk
Home office
Storage
Guest room
No insulation
Ugly lighting
Kid’s model
THE SPACE (2012)
Insulation
Insulated Floor
5’ high shelf at
top of foundation
THE SPACE (2013)
5’ high shelf at
top of foundation
Guest room
Cork floor
THE SPACE (2014)
Storage
Nice lighting
Storage
Home office
Modelling desk
Layout
TRACK PLAN
Alternative to
computer!
Version 1
ended here
Roundhouse
Staging
Total of 16
turnouts
Influenced by Lance Mindheim,
Trevor Marshall, Mike Cougill
“Freedom Layout”
Take advantage of sick kid
“proof of concept”
Learned a lot!
EARLY
OPERATIONS
These tracks need
to be long!
Ran out of
staging tracks
Roundhouse and
turntable make
this layout a lot
of fun!
WHAT’S THE
WORST THAT
CAN
HAPPEN?DE-RISK FIRST WITH A PROOF OF
CONCEPT
3D PRINTED SWITCH
TIES
Rail braces and slide
plates printed on ties
Ideal for 3D printing
- Quality less of a concern
- Thousands of possible
combinations
- Costs continue to come down
Half tie
HIDDEN THROW ROD
Throw rod hidden
under tie switch
rods to scale
P87 Stores point
reinforcing
Hard to get this right
Points want to rotate
3D PRINTED
TURNOUT PARTS Near scale switch rods
Finally settled on
plastic shim
BALLAST GROUT
Real dirt from ROW
in Pembroke Lots of dust
Mica
50:50 grout:dirt
PAPER SHELL
SCENERYPacking paper secured
with hot glue
Gaps open at edges
REFINE AS
YOU GO
AVOID ANALYSIS PARALYSIS
WORKING SWITCH
STAND TARGETS
Bullfrog
Switch stand target
Egregious hack!
More elegant solution
After 10 of them
(mostly all different) I
was pretty good at it
LED LIGHTING
“Warm” white
“Cool” white
Inexpensive on ebay!
Low profile
No layout
Started with three, added
one, then another before
happy
TURNOUT CONTROLS
Lego POC
3D printed in
sintered nylon
Needs to be thicker
Probably didn’t
need Bullfrogs
SKY EFFECTS
RGB Wash to
simulate sunrise
and sunset
Eliminate
shadowsNot purple
Purple
Waterproof 5050
RGB LED strip
Flip switches
ZERO-PROFILE
STAGING
Should look more
like a window sill
than staging yard
No ties. Code 55
PC board
rabbeted into
plywood
“Honey, why are
there a bunch of
tracks on the
windowsill?”
WHAT’S NEXT…
Lazy susan staging turntable base
Magnet-driven roundhouse doors
Hand-cranked turntable
Locomotive “kits”
Two controllers per train
Lots of debugging!
TAKEAWAYS
Don’t let your layout languish
• Either have a layout or a shelf
Proof of concept
• Explore new ideas, materials,…
• Verify if you have the skils
Damn the torpedoes!
• Refine on the layout
• Make progress
