Sixteen windows on carriages at a steam railway tourist attraction have been smashed in a second incident of vandalism in a week.
A spokesman for Telford Steam Railway said they would have to spend more than £1,500 to repair the damage.
Only a week ago thieves stole books worth thousands of pounds from the railway, which is based at Horsehay.
Volunteers are now trying to get the repairs completed in time for their Christmas special events.
Volunteer Mike Ross said they are upset by what has happened.
"The carriages are useless and of course we are starting out Santa Specials on Friday and we've got to try and get it repaired and replaced before then.
"It's just mindless. It's the usual mindless vandalism.
"It's happened in the past and now it's happened again. It's disheartening really."
