I have the s gauge polar express set. I do have the smoke switch on. It takes a long time to even get it to smoke a little. How much smoke fluid should I drop in the smoke stack?

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?

have you added the correct amount of smoke oil to engine ?



part number 6-37841 lionel

Sounds like a track connection not completely together. Put a meter on various points on the track to find where it is not completing the circuit.

The instructions are sometimes a bit vague: for example, once switched on the train needs to sit and charge before it runs, but that is not very evident from the instructions and many folks spent some frustrating minutes wondering why the train wouldn't move.

There is a small heater element inside and it has burned out.

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.

You may have to check if there is power to the heating element. You can also check to see if there is too much fluid. You can also put the engine in neutral and tap the chimney hole a few time to kind of "prime" the smoke unit.

indicates a dead short to ground in the smoke unit that is overloading the transformer
replace/repair the smoke unit
