The Downpatrick and County Down Railway is a private charitable heritage railway organisation which operates steam and diesel train services on three miles of track in Downpatrick.
The railway was hit badly by flooding in County Down in November and has still not reopened.
Police said they were still trying to identify the other suspects.
They are appealing for people with information to come forward.
