Duncan wakes up in pure confusion, finding himself on standard gauge rails in a location he's never seen before.
He sees steam in the distance and can hear a fast-paced chuffing.
A few moments later he hears Gordon's whistle. Gordon comes around a bend and is heading towards him at full speed!
"Eeerrgh, get out of my!"
Duncan closes his eyes as he braces for impact and his subsequent death.
...
Duncan wakes up screaming. He's looks around with panicked wide eyes, breathing heavily. He calms down once he realizes he's in the sheds, safe on his narrow gauge rails. He breaths a sigh of relief, seeing that no one is around to witness his frightened awakening.
What a strange and oddly terrifying nightmare!
