Abstract
A smoke generating device for a model train that includes a smoke generating element supported by a support member. The smoke generating element can be wound around the support member is a generally helical pattern. The number of turns and the distance between turns can be varied to enhance the smoke generating properties of the device. The support member can be braided fiberglass. A length and cross-section of the support member can be varied to support smoke generating elements of different lengths. The length of the smoke generating element can be varied to produce smoke generating devices having different resistive values.
