Over the weekend while I had the other trains at home, this bunch of mostly locomotives turned up on my shelf at the store. Since I’d never messed with taking a locomotive apart before, I was pleased when the Iowa Interstate came apart right in my hands. It didn’t have a brand name, but that’s apparently normal for genuine Athearn Blue Box locomotives and cars made between the ‘70s and ‘90s. These mid-level trains have well-detailed plastic bodies and fittings, and are known for their solid drivetrains. The underside of the cab (ceiling?) is strangely pebbled, and it took a minute to figure out the pebbles are kind of like BBs and add weight for traction. Further mass is added with the investment cast frame and solid metal fuel tank.
The motor and drivetrain are pretty cool. The center section where the green wires come together is the armature, windings, and magnets. The motor’s shaft comes out both ends, and on the right are the brushes (where the black band goes around the shaft). The shaft then goes through a large brass flywheel on both sides. After the flywheels are the smallest u-joints I’ve ever seen, then slip yoke shafts, two more tiny u-joints, and then the gearboxes. Power comes to the motor through the wheels and green wires. Everything turns smoothly, and though I didn’t have a transformer to power it up, I’m pretty certain she’ll run.
The Canadian National locomotive and baggage car make a nice pair since both are motorized. The Burlington Northern set includes a powered locomotive, unpowered locomotive, baggage cat, and caboose. The brown car has a damaged truck and that’s too bad since it’s a specialty tunnel-boring machine. The collection also includes the three blue locomotives, red caboose, and bonus Museum of Science and Industry black wax locomotive souvenir. There’s definite resale value in this bundle of collectible cars and locomotives and priced at only $125, there’s plenty of meat left on the bone.
