In 1904, the coming of the interurban electric railway made railroad travel possible between downtown Milwaukee and East Troy, Wisconsin, and at this location a trestle was built across a two-acre pond or waterhole in a pasture on the Kingston farm. The sinkhole appeared to be an ordinary farm pond bordered by a twenty-foot-deep marsh, but as interurban cars crossed the two-hundred-foot trestle, strange groaning and gurgling sounds came from below, leading John I. Beggs, supervisor for the TREM&L system, to nickname it the Devil's Teapot. On Friday morning, April 20, 1917, just after a westbound interurban car passed over it, the trestle collapsed into the sinkhole. After that, westbound passengers had to leave the car at Muskego Centre station east of here on Pioneer Drive, walk across a boardwalk built over the sinkhole, and board another interurban car to continue toward Big Bend, Mukwonago, and East Troy, with lanterns lighting the boardwalk in the evening. The TMER&L Company tried repeatedly to stabilize the crossing, first laying sixteen-foot oak planks across the sinkhole, only to have water ooze over the tracks, and then deciding to fill the sinkhole and lay tracks directly across it. Twenty-six workers from Milwaukee were hired for the effort, but over the next year the sinkhole swallowed dump cars full of gravel, ten thousand old railroad ties, and a thousand hand-cut trees from Big Bend while continuing to gurgle and bubble. One Friday night, seven railway dump cars loaded with gravel were left on the track ready to unload, and by Monday morning all seven had rolled in, sunk, and were never recovered. A year later the sinkhole was finally filled and tracks were laid across the trembling ground, but the tracks sank every year and workers had to raise them another foot each year until improved highways for cars and trucks helped bring the electric interurban into history.
