Residents are being reminded not to trespass on Island railways as work on them resumes.
Isle of Man Transport has warned anyone found to be on the lines without good reason could face a fine of £2,500.
Officials say in line with new rules issued by the government this week the works programme has commenced and that large vehicles, uneven ground and high voltage wires are just some of the hazards around the network.
The organisation has taken to social media to issue the message.
