They can only be powered from Head End Power (HEP) from a N Class locomotive or a powervan, as they do not have a dual power system.

Their capacities vary, generally around the 300 mark though - ideal to cater for the large amounts of commuters using peak hour services to the city in the morning, and from in the afternoons.

Their are 52 First Class seats in the ACZ carriage, and usually over 200 in Economy.

Neither of the VZ sets have snack bars - as all BRN buffet cars are permanently marshalled in N type sets, plus the purpose of VZ sets is to increase seating capacity for peak services.

Wheelchair access is available to disabled passengers via the wide East End entrance doors of the BZN carriages, or when marshalled in the set, ex WCR carriages ACZ252, ACZ257 & BZ267.

A conductors van, which is significantly smaller than that of an ACN type carriage can be found at the East End of the ACZ carriage.

There are two VZ sets- VZ1 & VZ2, with the makeup of these sets changing on a monthly or so basis.

Note: Usually during the school holidays, VZ sets are broken up so that the carriages from them can be added to other N type sets to provide more capacity for this busy period of time. This has also occured during recent Seniors' Weeks.
