Victoria Transit Patrol Department, also formerly known as Victorian Railways Investigation Division, was a state government law enforcement agency that was in charge of responding to and investigating crimes that took place on railway property throughout Victoria, Australia.

They were expanded in 1890 with the introduction of officers who made random checks at railway stations to arrest those who evaded fares.

It was approximately one year later when the department became managed by the Victoria Police while still coming under the Metropolitan / State Transport Authority's umbrella at which time it was renamed the Transit Patrol.

When working undercover, officers had the choice of the Ruger Police Service-Six or the Smith & Wesson "Chief's Special" stainless steel 5 shot in .38 calibre.

An "H" key was also issued to enable officers to travel between carriages through the communication door to apprehend offenders and to close Railway Stations to the general public in case of emergencies.
