A simple Google search shows its 0n30 scale.

The Atlas turntable works great with EZ track and is inexpensive plus it has a great matching Roundhouse.

The Cars in this set have interior lighting which pick up power from the rails via the wheel sets, make sure one or all of them are not shorting out the controller. Try the cars one at a time and see if the Engine runs. The wheel sets must have the insulated wheels all on one side on one truck and the opposite on the other. They could have been installed improperly.

Hi Jonathan: use 'Lock-tite' on the screw and put it back in. It will stay in. Get it at any auto supply store.

Three was to check for that and its not Polarity, you are simply checking continuity. Use an ohm meter or a simple 12 volt light to check for current or just old fashion trial and error.

I had to remove the coupler pockets on my GP 7'S and 9's to get the shells on.

If you checkout the product search section you will see that the wire is available on its own, or you could just by some 12 guage wire and a pair of terminal connector track clips from Atlas and make your own or just solder the wire to a pair of track clips.

I mostly use Tamiyas Extra Thin Cement  in the square 40 ml bottle and apply it to the back of the model and allow the cement to wick through into the hole. If the hole dosent go all the way through just drill it out with a pin vice.

Easy-attach alligator clips to the tender wheels.

It sounds to me your wheels need a good cleaning. Hunt posted this away back and its still the best wheel cleaning instructions I have seen here.
* Locomotive wheels *
"Cut a Handi Wipes or the like in four inch strips, DO NOT use kitchen paper towel. Place one strip across the track and soak the towel part over each rail with about a half capful of Isopropyl Alcohol. Place one truck, for a diesel, on the wet towel and the other truck on the track. Hold the locomotive with one hand and slowly turn up the power pack throttle to spin the wheels. When these wheels are clean, turn the locomotive around and do the other truck. Spin as many wheels as you can at a time for steam locomotive. If wheels very dirty use “Goo Gone” (not recommended for use on rubber traction tires) all-purpose cleaner in place of the alcohol and gauze pad in place of the towel. After wheels are clean then spin wheels on dry towel to remove the cleaner residue. . If you are using DCC make an extra effort to remove the cleaner residue. Finish with very, very small amount of conductive contact lube on each metal driving wheel tread and electric pick-up rub points."
An alternative to alcohol is Aerolubes ACT 6006 cleaner. For very dirty wheels some type of paste metal polish can be used on the cloth to polish the wheel face then follow up with alcohol to remove residue

Hi Jeff: coupler pockets come with every package of Kadee's. Haven't you every bought a pack? It's a simple matter to cut off the pocket attached to the truck and glue or screw Kadee's to the body. Its more prototypical and the car will preform better.

Mickey a Shay is a geared engine and it runs slow because that is fast as the real ones could go. Top speed for a shay was 15 mph and usaually ran much slower.

A DTDP switch will work as long as its momentary or you will burn out your coil. You may want to try an Atlas turnout switch.

Dave

Make sure you have a DPDT switches connected to the loop and the mainline.
