Update, June 12, 1.44pm:
Police investigations into criminal damage to Bendigo's Royal Tram in April are ongoing.
Investigators have released an image of a person they believe might be able to assist with their inquiries.
The heritage tram was installed at Rosalind Park's piazza about a month before it was damaged.
The decorated W2 Class Tram 275 complements Bendigo Art Gallery's Tudors to Windsors exhibition.
Investigators have urged anyone with information to contact Bendigo Police on 5448 1300 or to make a confidential report to Crime Stoppers on 1800 333 000 or online at crimestoppersvic.com.au
Vandals have smashed two windows and tagged the back of Bendigo's Royal Tram on Monday night.
Chief executive of Bendigo Heritage Attractions Peter Abbott said he was "frustrated and disappointed" by the attack.
He said he hoped the offenders were caught on the many CCTV cameras near the tram. The Rosalind Park location for the tram had been partly chosen because of these, Mr Abbott said.
Mr Abbott's main priority was to restore the tram in time for the crowds of tourists that have been using it as a selfie-spot, he said.
The inside of the tram appears to be undamaged.
Mr Abbott said the graffiti should come off the back of the tram without too much trouble.
Heritage Attractions will do some patch repairs and get the windows replaced.
The cafe should be able to open as normal on Wednesday, Mr Abbott said.
The incident has been reported to the police.
