Well how about the transformer still storing and providing a voltage? The light on a laptop transformer for instance, still glows for a couple of seconds even after the transformer has been disconnected from the mains...
@anyjaszemit Laptop transformers have lots of regulatory and current-smoothing circuitry (capacitors etc). I've taken one of these train transformers apart, and they're dead simple, just the transformer, a single mosfet, and a potentiometer. I've tested and run a many bulbs from a train transformer and they're always instant on, instant off.
That was great.

Good thought though.

Are you sure the lightbulb doesn't stay on because it's hot and is cooling off? It's a possibility that came to mind.

@chainer2322 Nope, it goes out instantly if I short the leads.

Good call. I would have to agree with you then :P
