Thanks. One of beauties of LEGO: You can build your own, the way you like it.
Just some new comments about the orange TGV. I have had some time to revise
the shared bogie coupler between the passenger cars. This newer design has no
extra pivot pieces, as the older design did. The only built-in pivot is on the
bogie plate. There are two "tongues" that fit into the ends of the adjacent
passenger cars: one tongue into each car. One of the tongues only translates
"in-line" with the length of the car. The other tongue can both translate
"in-line" with the length of the car AND rotate along that translation: this
rotation and translation is nearly identical to the coupler used for the BOB
train. All the cars are still connected by using yellow LEGO rubber bands.
I have also been able to add a third passenger car to the orange TGV. No
pictures, yet. This makes the train 5 units long. With the new shared bogie
coupler design the train snakes more smoothly through complex "S" curvy-curves.
Having two shared bogies on the train really makes a difference in the entire
look of the train. Through straight-aways the train's looks just scream for
full-throttle speed! I only wish I could say that the train could enter and
take a curve of 90 degrees at full throttle, but it can't. Just too much speed
for its design.
Even though I don't think the real TGV Sud-Est in orange has any double deck
observation cars, the third passenger car uses the 4559 Cargo Railway hinged
canopy trans-light blue windows and has two levels. I wish I could've used the
2 brick tall thin wall trans-light blue windows and kept the same look for each
passenger car, but I don't have *that* many of those windows.
Using the rubber bands to keep the cars close-coupled really makes the train
look quite sleek on the straight-aways, even though it does look a bit more
ungainly on the outside of a section of curved track. Need some kind of LEGO
expandable bellows between the cars to expand along the outside diameter
through curves to maintain a more "solid" and connected look.
Thanks to all who visit the pictures.
later,
James Mathis
