Victorian Railways initially numbered passenger and goods locomotives separately, the engines were delivered with numbers 26–31, 52–63, 70–81, 88–89. This system was changed before these locos entered service to odd numbers for goods locomotives and even numbers for passenger locos with these locomotives taking the odd numbers 19–81, 127–149. An unknown boiler from either an O or
B class was used until 1941 to power the refrigeration plant at Spencer Street where ice was made for T vans. ==Fleet summary==
