A man has been charged over the alleged knife-point robbery of a woman on a train earlier this month.
The 21-year-old Penrith woman was on a train travelling west abut 9.45pm on January 7 when a man allegedly threatened her with a knife before taking her backpack, wallet, and mobile phone.

He was refused bail and will appear in Blacktown Local Court tomorrow.
Police will allege the second charge relates to a robbery at Cambridge Park on January 6.
