MEDFIELD - The town will have to replace a fire engine that was damaged by an electrical fire last month.

The Fire Department's Engine 3 caught fire on Thursday, May 2, during checks of the town's trucks. Fire Chief William Carrico said the vehicle was a 35-year-old Mack truck.

"In order to stop the fire, we had to disconnect the battery," he told selectmen at the board's June 4 meeting.

The department, Carrico said, immediately filed a claim with the town's insurance company, and soon learned the vehicle was considered a total loss. The truck is currently at the Medfield station, and firefighters have moved its equipment to the department's operational vehicles.

Carrico said he had obtained a loaner vehicle - a 30-year-old truck - from Specialty Vehicles of Plainville to cover the town's immediate needs.

"It's not a long-term option," he said.

Carrico told the board that he would be recommending a replacement, at a cost of about $535,000. Engine 3, he said, had been used for emergency response and specialty hazards.

Selectman Michael Marcucci said such a large expense would have to go through the town's capital budget. Carrico said he understood that, and was simply trying to give the board a sense of the upcoming request.

Marcucci suggested the department include supplemental information about the roles of different fire vehicles, and their necessity in addressing emergency situations that might arise, when it makes its presentation to the capital budget committee.

The department had sought a replacement for the truck - which dates back to the early 1980s - in its capital requests this year, but the capital budget was curtailed  to balance the town budget.
