And in a bid to head off any disruptions, those trains will be monitored by two new drones.
Metro previously rented drones to monitor major events such as the Grand Prix, but the new purchase means they’ll be used more often to track crowd sizes and detect trespassers.
“They will be used extensively in this and future events. It allows us to zoom in and see what’s happening from above, especially to watch trespassers that might slow our trains,” Metro chief operating officer Catherine Baxter said.
“We’ve spent many weeks working hard to prepare the network to be as robust as possible. We can spot vandals and keep our trains going smoother and safer”.
Metro have also introduced a CCTV trailer which can make use of thermal imaging to target vandals and trespassers at night.
Images recorded will be stored by Metro and passed on to police.
Anti-horseracing groups are expected to be joined by other activists at Flemington this year and Victoria Police say they will monitor the event closely.
Police are being stationed at level crossings near Flemington Racecourse, such as Kensington station.
On Melbourne Cup day in 2017 a car was driven on to train tracks and its tyres deflated with a woman inside the vehicle as part of a protest over the treatment of asylum seekers.
In a separate incident, a banner was unfurled from a crane above the Flemington track.
“We respect the right of anybody to exercise their right to peacefully protest, but we have many people travelling in our public transport and its important that we make sure that the network keeps moving,” Public Transport Minister Melissa Horne said.
