[fktco00007]

It's maybe a stupid question.I want to buy a HO scale SPECTRUM HO SHAY TSUNAMI SOUND TRAIN,but there's Some doubt :
1.Is the smokestack plastic or metal?If install the smokegenerator,OK? ( SUETHE SMOKE GENERATORS ?)
2.Is the smokestack upon  the type of model? Can the diamond or upright shape be exchanged?
3.Except the smokestack,is any different about the shay (Product Code 80701-84705) ?
Thank's for help!

Dear f,
The Shays have a variety of plastic stacks. Installing a smoke unit is possible, but not easy.
Have fun!

The locomotive comes with one stack and it is installed. If you require a different stack, you will need to call the Parts & Service Dept. and order another stack and inquire about the price.
