Kangaroos collide with V/Line train almost every day, causing rail services to be canceled and some train unable to work for up to three days, the Times reported.
From March to October, V/Line train hit kangaroos and other livestock 60 times a month, causing commuters to face longer delays.
The hot spots where the kangaroo was hit were along the Bendigo, including Kangaroo Flat and Chewton, and the Seymour circuit in Wallan.
At its worst, train hit nine kangaroos in a day.
The public transport bureau's data analysis shows that only 50% of the V/Line train of some routes in the sub-developed areas will arrive on time, and the railway network in the sub-developed regions has failed to reach the punctuality target in the past six years.
Since 2015, the percentage of V/Line train cancellations has almost doubled to 3.7 percent. This year, more than 300 Bendigo train have been cancelled, accounting for 3.2 percent of the total.
At Seymour, a total of 200 rail services were cancelled, up from 120 in 2017 and 2016.
A spokesman for the V/Line said that from March to October, there had been 491 animal crashes in the railway network, averaging two per day, and that late peak hours were even more frequent.
It is understood that almost all such collisions will kill kangaroos, but they will not bring threat to passengers' safety, but will only cause some damage to train.
"We are all working hard to make sure we get everyone where they need to go," the spokesman said. "but the increase in animal impacts has affected our ability to serve people in recent months."
After train bumped into an animal, V/Line train was usually asked to stop service and send empty passengers' train to Melbourne's South Dynon and West Melbourne's maintenance facilities for cleaning up. There, train will undergo a day-long "biological cleaning" process, where workers will clean up the remains of animals and thoroughly clean up the train.
The whole process causes train to stop running for one to three days. This will also file in the system, increase the number of train cancellations, but also lead to a reduction in the number of cars. This means that train was forced to operate busy routes with fewer vehicles, leading to greater congestion.
Since October, there have been 695 train trains running in the absence of carriages.
A spokesman for V/Line said they planned to reduce the time train would stop service due to cleaning requirements.
Jacinta Allan, the director of public transport, said they had the opportunity to build more maintenance and biological cleaning facilities and institutions in subdeveloped networks.
Graeme Coulson, an associate professor of zoology at the University of Melbourne, said there was no data showing an increase in the number of kangaroos in Victoria, but he also found that the number of kangaroos being hit by cars had recently increased.
The state currently has nearly 1.5 million kangaroos, according to the state planning bureau.
There are 17,500 kangaroos in the Greater Bendigo area.
