There is a sequence for a flickering light. This could be used with a yellow LED to represent a candle or oil lamp in a draughty building. Or it could be used with a red LED to symbolise a fire.

You could make a sequence to operate a fire scene on your railway. One sequence could make the output go on for one minute every 5 mnutes, and would power a smoke generator. Two other sequences couyld be used for different kinds of emergency lights (e.g. police and fire). Use the "output gate" function to make the emergency lights operate when the smoke generator is on.

You could use a sequence to make a windmill operate for a few minutes then be idle for a few minutes. yuo could use a sequence operating a servo to move the windmill very slowly to face into the wind.
