I had the misfortune to have to take apart my Super 381, so I thought the inside of the thing might be of interest to some of you. Mine is the conventional version, painted for Milwaukee Road Olympian Hiawatha. The locomotive is powered by two repro Bild-a-Loco motors running off of one old-fashioned electro-mechanical E unit. There are four idler wheels under the cab, set up in what looks a lot like most of a 400E leading truck. The wheels are sprung in exactly the same manner as a 400E or 392E. The most interesting feature is the superstructure bolted to the top of each motor. If you look closely, you will see a black steel block sandwiched in between the sheet metal sides. These are traction weights, giving the unit its very considerable heft and, most likely, plenty of traction.
The problems that caused me to pull the unit apart underline the absolute necessity of bolting the unit correctly into the cage when shipping. I got this unit off the Bay from what I think was an estate sale. The unit rides in a steel cage that sits inside the box. The pillars that screw into the trucks to hold the unit in place in the cage were not properly in place, and one of the 6mm screws was broken off in the body of the pillar. The unit had been padded for shipment, but some handrails and the bell were pretty bent up, and the couplers were pretzeled. I had to remove the body to deal with the handrails. Getting the body off was easy; it's held in place with four screws on the center section of the frame. Getting it back together was a problem as the frame was a bit sprung and it took a lot of pressure to get the screw holes to line up.
Fixing the thing was a pain, but on the other hadn I got it for a bit under 900 bucks, shipped, which is a considerable saving from the $1299.95 MSRP.
One question for anybody who bought one of these new. The catalog shows flagpoles in the holders on the pilots. There were no flagpoles on my unit or in the box. Were these units in fact supplied with flagpoles, or is this just another case of artistic license in the catalog art?
Here are the pictures, with and without the body. I also took a picture of it next to a 385E for a size comparison. The Super is about two feet long. I also added a couple of pictures of the matching observation car.
