Forty guards vans were built and placed into service between 1956 and 1958. They were coded CP and numbered 1 - 40. One van was destroyed in a collision at Broadmeadows 1958.
To replace the ZJF_ vans in Joint Stock service, nine CP vans were recoded to JCP_. These vans were not required from the mid 1980's and were converted back to CP with their old numbers.
The 1984 recode for these was VVCP.
The CP vans were recoded to VVCP between 1983 and 1986. The numbers were reduced from 1987 with conversions and removal from service.
In 1987, four vans were placed into passenger train service. VVCP 6, 16, 25 and 34 were reclassed to CP 294, 292, 293 and 291 respectively. When control of these vans was passed to 'West Coast Rail', a private operator, the class was altered to PCP.
