Some St. Joseph residents are worried that the bluff below their property is eroding and could collapse, taking railroad tracks along with it.

The Herald-Palladium reports that residents along Old Lakeshore Drive expressed their concerns Monday to city commissioners, who said they shared their fears of a possible train derailment along the CSX Transportation line that carries Amtrak passengers and freight cars.

Houses along the road aren’t in danger because they’re on the opposite side of the street.

Mayor Mike Garey says that based on photographs, it appears that a collapse isn’t “a matter of if, but when.”

Anson Lovillette says that for 15 years, he has been sending letters and photographs to CSX officials, who have assured him they’re monitoring the situation.

The newspaper couldn’t immediately reach CSX officials for comment.
