Polar Express locomotive will not smoke with smoke fluid in stack and smoke switch on.

Hi,

Please make sure that the wireless controlloer power switch is set to "on." Please also give the train a new command. If it does not start to run, either your engine or remote need repair and you would need to reach out to Lionel by calling 1 (586) 949-4100.

Thank you.

Make sure the batteries are in the right position in the battery box .....The springs are the (-) negative flat end of a AA battery...Compress the spring with the flat end of the battery and push the nipple end (+) into the battery box...it should snap right in....There should be an on-off switch on the locomotive as well..............

No more than 1/2 teaspoon at a time. Less is more.

There are different versions of the Berkshire 2-8-4 locomotive that comes with these sets and the process of activating chuff sound on them varies depending on which version of locomotive you have.So in order to help you I need to know which one it is. Do you have the model number of your set?

No.

Remove the shell. Soak up as much as you can. Leave out to dry or use a hair dryer on low until controls are dry.

Most Lionel engines have a small slider switch which can turn off the smoke generator. Check to see that the switch is in the ON position. Check the engine manual (available from Lionel's website) for the location of the switch.

Also, if the smoke generator is always on and no fluid had been used in the generator, it will eventually burn out. Replacement smoke generators are available from Lionel.

No doubt the transistor in the motor controller inside the engine is shorted TIP31C Q6 If you have the skills you can repair the unit. Parts are cheap, like 50 cents. Expense is shipping. Have repaired at least one that had the probblem you describe
good luck

There is a small screw hole on top of the train, down inside what looks to be the smoke stack.  Then insert 2 AAAs!
