The train gag in which Shaggy made train noises and Scooby went down the tracks holding a flashlight to simulate a train to scare the Miner 49'er is parodied here
The Galloping Goose mimicking a train in a tunnel to scare other cars out of his old railroad tunnel is very similar to Shaggy and Scooby's own train imitation in a mine tunnel to trap the Miner '49er.
