Something I noticed while driving past the rail yard and while watching
"Extreme Machines" or was it "Trains Unlimited" is a trick that both
high-speed trains and freight trains use to reduce rolling resistance.
The trick is to cut down the rolling resistance by cutting down the
number of bogies/wheel sets. Instead of each car having two sets of
wheels, two cars are connected to one sets of wheels. I regularly see
flat bed cars that have wheels arranged like this.
____car____ ____car____ ____car____
x--x x--x x--x x--x
instead of the standard
____car____ ____car____ ____car____
x-x x-x x-x x-x x-x x-x
Anyone working on a reduced wheel set design? There are certainly some
interesting technical issues invovled. Anyway, just trying to spark more
discussion.

| (...) Hi Chris, I did just this with my #4559 about 18 months ago. I built stretched 2 wheel "Super bogies" that support the ends of adjacent cars. And, since the train end (tail) has the same s-bogie, I fashioned a tailcap that continues the train (...) (26 years ago, 20-Mar-99, to lugnet.trains)
