Summary: | The OCA was arguably the final development of the traditional, general-purpose open wagon although the decline in general merchandise traffic resulted in the type never being fully employed. Most of the OCAs were soon transferred to departmental use, while others were rebuilt as timber carriers. The latter have now mostly been replaced by bogie types, with the unmodified wagons remaining on infrastructure duties. | |
Profile: |
NB: This is a brief profile. It will eventually be upgraded to the standard of later profiles, with more detailed information.
The fleet of 400 OCA wagons arrived a couple of years after the OBAs, but looked much more modern due to their all-steel bodywork. Designed as a general purpose open goods wagon, the OCAs had three drop doors on each side, with removable stanchions in between. Turnover bolsters in the floor made the type suitable for a variety of loads.
Delivered in bright red livery with the Railfreight logo in white, the type could often be seen in Speedlink consists, reaching many parts of the country. The decline in general freight traffic hit the type however, and in 1984 about 150 were transferred to departmental use as type ZDA 'Bass'. The numbers were prefixed with a DC (or ADC) and many received the grey and yellow fleet colours. A more drastic change was the rebuilding of many as OTA timber wagons.
The remaining OCAs were evidently still under utilised and further conversions took place, both to OTAs and to ZDAs. Many of the original ZDAs were later rebuilt as ZCA 'Seahorses', with low-sided steel bodies suitable for ballast and spoil loads. These initally carried the grey and yellow colours.
Sectorisation and privatisation affected the fleet liveries. Many of the remaining OCAs were repainted in the new Railfreight livery of dark grey with yellow ends. Under EWS's policy of resource pooling, most of the unmodified ZDAs were recoded back to OCAs, many still retaining their original livery. It is not known if any OCAs received Loadhaul, Mainline or EWS livery.
