All of the vehicles seen in the photo below are wire-following O-Gauge models on my layout, but the three out in the traffic lanes are new this week. From left to right among those three, they are:
a 1961 Chevrolet Corvair Greenbriar made by NEO
1947 Cadillac 62 Sedan made by Brooklin,
1960 Ford Ranch Wagon made by PremiumX.
The two wagons were converted to wire-following operation by AutomotionFX and are excellent runners. The Corvair is particularly noteworthy because it is a resin model: the first resin model I have ever seen converted to wire-following operation in any scale. The Cadillac is a Brooklin model that I converted to wire following myself, making the entire magnetic tiller-operated front suspension and chassis/frame from Evergreen sheet styrene, and using "robotics hobby grade" motors and gears for the drivetrain. It is powered by two 3.7 volt rechargeable Li-Ion 10440 batteries and runs at a scale 23 mph, perfect for cruising down Main Street on may layout.
A video of the Cadillac running on Main Street, and a look at slight problems it had due to its long wheelbase (1/4 longer than anything else I have run) can be seen in this video. At one point its jumps a corner curb, at another its rubs against the edge of a , a tunnel portal. (I've since rounded the corner curb and widened the tunnel portal. )
