A fire at the Cambrian Railway Museum in Oswestry is being treated as suspicious by police. The blaze, which caused damage valued at �15,000, started on Wednesday night in a 1950s former British Rail carriage on display at the museum.
A spokesman for the Cambrian Railways Society said the fire has put plans to take part in the Home Front World War II festival next weekend in jeopardy.
Police have arrested two teenagers on suspicion of arson.
