OBA Loads


Recommended Posts

I think they were used in conjunction with a flow of very large diameter pipes from Stanton Ironworks to Teesport for export about a decade ago- the trains were formed of alternate 4-wheel opens and BPAs, with corresponding lengths of pipe.

The OBA design was originally modified from the OAA (the prototype wagon was originally to be coded 'S**'), in order to be able to load tubes from BSC Corby, replacing vacuum-fitted stock. Unfortunately, there were clearance issues (perhaps due to door bangers?), and the vehicles couldn't use the loading bays....

Notwithstanding the problems at Corby a pool of 50 OBA's was assigned there until the early 1990's to carry steel tubes. Amongst the destinations regularly served were Bow, Cardiff Canton, Leeds Stourton, Mossend and Middlesbrough and they were a common sight in Tees Yard en route to Dawsons. However, whenever I saw them carrying tubes they were always sheeted so that you could not see the load.

 

When working from Stanton in 2000 they ran to both Hull Docks and Tees Docks with large diameter pipes for export, the destinations including customers in Peru and the Persian Gulf. In this case a single unsheeted pipe was carried while SPA's and BDA's were also noted in this traffic.

OBA wagons have been used to ship reinforcing wire coils from the Cardiff Rod Mill, and are still so used.

.

In addition, OCA wagons were used by EWS to transport a specific coil product called 'Contistretch' from Allied Steel & Wire, Cardiff.

.

But in the case of the 'Contistretch' loads, the coils were carried 'eye to the side' whereas the standard reinforcing coils carried in SPA / SEA wagons were usually carried lengthwise.

.

So, you can load both OBA and OCA wagons with coil, and cock a snoot at the rivet counters who say you should use SPA and SEA wagons.

When we still had steel trains into Mostyn (mainly long strip on BDA wagons) I remember one occcasion, around 2005-2007 when a OBA (may have been recoded by then, I have a photo somewhere) was added to the train which originated from the North East, to take away "scrap" wood packing used between layers of steel on the wagons. Perhaps the Port of Mostyn had ordered a clear up. Either way gives a nice excuse to add an OBA!
