Train rear-ends another train in Vic

A train has crashed into another in Melbourne's west, injuring passengers and staff.

The rear-end collision occurred about 7pm with both trains on the same line, heading east towards central Melbourne.

A passenger train carrying about 60 people had come to a stop near the Maidstone St level crossing, in Altona.

Police say another train from Geelong, with only a driver and conductor on board, ran into the rear of the stationary train.

Nine people - seven from the passenger train and the two from the Geelong train - had minor injuries, police say.

Police and emergency workers have remained at the crash site well into the evening.
