Model Power E-units were made by RoCo, and they are some of the better running models of the 1970s. The Model Power E9 looks better than an earlier model, the Rivarossi E8, usually sold as an AHM E8. The RoCo E-unit shell has its inaccuracies, but it does a good job of capturing the look and feel of an E-unit. Many of these models are nearly 30 years old, and even when they were new, these models were oddly noisy.
The RoCo drivetrain is unusual, with an enormous can motor, an enormous single flywheel, no real truck bolster, and axles that fit loosely in their slots. Look at how the trucks articulate to the frame and then remove the trucks by removing the brass machine screw on the bottom and sliding the truck forward (and catching the dog-bone universal joint and any springs in the universal joints; see below). Clean all the wheelsets and gears with isopropyl alcohol, and use a toothpick or cotton swab to remove the gunk. Remove the front coupler entirely and make the slot in the pilot smaller by filling it in with styrene. Once you are done with all modifications, clean the body, plastic frames, and fuel tank in warm water with dishwashing liquid. When the parts are dry, mask off the electrical contact areas and internal parts of the truck frames and paint the main frame and truck frames with flat black rust-inhibiting paint.
Reassemble the trucks by putting all the gears in place, lightly lubricating the axles with plastic compatible oil and the gear teeth with plastic compatible grease. Then install the wheelsets, making sure that the insulated side is on the plastic side of the gearbox. Test-run your unit-- sometimes, the locomotive will run better in one direction than the other.
Install couplers, put a small piece of double-sided tape or velcro inside the body to hold it on, and reassemble.
Even with the changes noted above, it's difficult to build a stock Model Power E-unit into a truly quiet, great-running model. Use the shafts and couplings in the A-Line kit to install the rear truck-- you'll need a ball coupling, two keyed couplings, and a keyed shaft.
For the other end of the motor, take one of the 4-slotted couplings from the A-Line kit (this part is normally found on an Athearn F7) and drill out the center hole with a number 32 bit (or 3.0mm). The front truck uses a ball coupling and a keyed coupling just like the rear truck, and you can use the appropriate piece from the A-Line kit to connect the motor with the front truck.
Got this a couple weeks back in a trade in another forum with the idea of modifying it with close coupling and Favely pantographs. Amtrak never ran this train, it's a Shinkhansen, the nose actually lights up in real life, too.

Power Trains are motorized, highly detailed, and authentic looking trains that feature battery operated engines with 2 speeds, working headlight, and work both on and off track. However, with a careful and complete tune-up, they can be made into quiet models that run well and out-pull models costing much more. The drivetrain is made to extremely loose tolerances, but it's sloppy in ways that allow the trucks to articulate well over rough track.


The E9 hole is easily filled with body filler, while the E7 hole is most effectively filled by gluing a small detail part or scrap piece of plastic that matches the similar object on the rear hatch. You can correct this by replacing the sides with plastic detail parts or by fabricating new tanks. Drill and tap a 2-56 hole somewhere on the tall crosspiece at the front for a ground wire. The motor drives the flywheel with a slot and key coupling; on some late units, this coupling is made of flexible rubber, which may be degraded with age. One trick to make the units track better on sharp curves is to narrow the gauge of the center wheelset ever so slightly (this is a good trick for any 6-wheel truck). Flush glass wasn't made for the side windows, and it takes forever to cut out, so while I'm waiting, I paint the edges of the window frames flat black (Floquil Engine Black applied with a toothpick works well). Part of the problem lies with the design of the dog-bone couplers (they have a lot of end-to end play and the two ends are inline rather than offset 90 degrees), part of the problem lies with the slot and key coupler for the flywheel (it requires perfect alignment of the motor and flywheel), and part of the problem lies with the motor (which seems prone to cogging even when carefully tuned).
You'll need to remove 5.0mm from the pointed shaft, and 18mm from the long shaft on the terminal end of the motor.
I have the Amtrak version, there's a blue and white version I just got a set of at Timonium MD show, and also a Coke version.
I was wondering what diameter the Rivarossi wheel are.I looked at the AHM part lists to see if wheelsets from anything else would interchange but it doesn't look like it. I've never seen those wheelsets in the stock they bring, but I would be surprised if they didn't have them.

This toilet very wellspring go an expensive hobby if you are relying on trial run and fault for learning. A decoder such as a TCS T4 LED works extremely well with these locomotives, as long as the motor is in good shape and doesn't draw excessive current.
Remove the body shell by removing the large screw on the winterization hatch (E9) or behind the cab (E7). Some E9 units were sold with the steps in the proper location for an E9, but many were sold with the steps in the E7 location, or no steps at all. It's surprising how quickly this swap will improve a locomotive, especially since the alternative is to settle for a poorly-running locomotive or to spend hours troubelshooting.

One side of the model picks up power from all 6 axles and is grounded to the frame, while on the other side, 4 axles pick up power from wipers. Remove the fuel tank by carefully rocking it back in forth; it's held in by two lugs that fit into the frame, and the brown plastic of the fuel tank and trucks can be slightly brittle with age, so the lugs may break off. Some units have black gears, but most have red gears; if the gears are discolored (pinkish), they should be replaced. Denatured alcohol usually works, but it may take a long time and it may not fully remove all the paint from crevices. A good source of thin washers is the worm gears; washers from the worm assemblies may be removed and used on the flywheel and replaced with thicker shim washers from an Athearn unit. Place a small dab of silicone caulk in the coupling as you assemble it and let the caulk leak around the edges.
Spare parts are hard to come by, but many parts are shared with other RoCo locomotives, including the Model Power Shark, Model Power FA, Atlas FP7, and Con-Cor E7.


If one breaks off, when you reassemble, use double-sided Scotch tape to hold the fuel tank on; if both lugs break off, glue the tank back on when you reassemble. Some units seem to have been soldered with acid flux solder so the wiring may be extremely corroded.
The locomotive should now be in pieces, and you're ready to start the cleaning and tuning process. If you have an E7, now is the time to remove the number indicators (although I usually leave them). Although a frame-mounted coupler would be ideal in the rear, there is not a lot of room for one. If you have an E9 with the steps in the wrong place, now is the time to carve them off, or scour swap meets for the correct fuel tank. Shimming the worm gears is probably the single most effective way to quiet these units; out of the box, the worm gears have excessive play, and the stock thrust washers are far too thin to limit play.
Secure the motor with the original clip, or, for a firmer mount, with strong tape (I use Gorilla Tape). Dummy units of all these models can supply parts, though beware that some (but not all) dummy units lack any gears at all (even on axles). In all units, the wiring seems slightly undersized, so I typically remove all wire, solder, and flux and start over.
I truck-mount the rear coupler removing the existing coupler and sawing most of the box off with a hobby saw. Then rotate the flywheel and spread the exuded silicone evenly around the outside of the coupling to make a thin layer. Model Power HO graduated table civilize Set demonstrate for operating purposes only model power trains. On the E7, one of the exhaust stacks was also a sprue location; you'll need to sand and carve that stack down and drill it out to match the others. Then I place masking tape over the top of the two small openings in the tab sticking out the rear of the frame, flip the truck frame over, and fill the holes with epoxy. This will prevent the silicone from popping out of the key, since it won't really stick well to the plastic. The most important part of building a good model is to acquire enough spares that you can pick the best parts to build one unit that runs well.
It's also a good time to cut open the chicken-wire intake grills on the sides; I cut them out by drilling holes and carving with a hobby knife, leaving some pieces in place to match old photographs of carbody framing. When the epoxy is dry, I drill and tap a 2-56 hole where the original coupler pivot was and I mount a short-shank offset coupler. You could remotor the unit, but the motor is not the only source of the drivetrain noise, and the gigantic motor is also one of the great selling points of this model, so I'd suggest keeping it-- as long as you've got a good one. Then, scrape off the molded-on chicken wire, retouch the paint, and glue wire mesh or stainless grilles in place. The plastic does not seem to become brittle with age, and it's soft enough that this is a relatively easy modification.
