The Rail and Maritime Transport Union is calling for the safety of train staff in Auckland to be improved after two assaults at the weekend.
The union says two train inspectors working for passenger rail network operator Transdev were assaulted at the Ranui and Swanson stations on Saturday.
In one of the incidents the worker was attacked by about eight people, leaving him with a fractured eye socket.
Union Auckland regional organiser Stuart Johnstone says the incidents highlight the need for more security on the network.
He says it might be time to increase staffing from one to two managers per train, and more Maori wardens could also help.
Transdev says it increased the coverage of security personnel on trains late last year and has employed a security manager to liase with police and Maori wardens to help resolve incidents.
