During
the early 1970's and in response to the changes in worldwide
transportation, the NSW Public Transport Commission embarked on a major
container
wagon building programme.
A
total of 560 63' container wagons were built over a six year period in 9
contracts. These wagons were suitable for carrying 3 x 20' containers or
1 x
40' container and 1 x 20' container or two 25' refrigerated containers.
In
1974-75 Commonwealth Engineering, Granville were awarded two contracts
in the OCY programme, the first was for the wagon series numbered 14901
to 14950
and delivered in PTC Blue. The second contract was for the wagon series
numbered 15001 to 15070 and delivered in PTC Indian Red. They were
fitted with high speed, one piece, bogies meant these wagons were
suitable for attaching to passenger trains.
Commencing in the mid-80s
the SRA started to recode some NQOYs to NQOF and NQPY. These
wagons had their 2CM bogies replaced with 3 piece roller
bearing types and were used for Intrastate loading.
During the early 1990s
further modifications were undertaken, tare weight reduction
with sections of steel deck sheeting and the equipment boxes
removed and the container locks were upgraded to marine type
twist locks. These wagons were recoded NQSY and NQBY and later
migrated into the NRC fleet in 1995, they were again recoded
to RQSY and RQBY.
With the formation of Pacific National in 2002 all NRC and
FreightCorp wagons were pooled together with the FC wagons
retaining their N coding prefix.
