Wich says the museum had been warned that one of its priceless artifacts — a vintage Nathan M5 Airchime Train Horn was at risk of being stolen.

He says pictures of the horn were found circulating on a Discord server in the United States.

“The fellow that saw it there actually phoned a friend of his up here who is a collector, who then immediately phoned us and warned us that perhaps our horn was in jeopardy,” said Wich.

The museum staff immediately tried to remove the horn for safekeeping from its position atop a locomotive but couldn’t because the bolts were rusty.

When they returned the next day with the right tools to remove it, they discovered it had been stolen in the middle of the night.
