In 1980 Procor built 18 barrier wagons for Railease which were used between Haverton Hill (Immingham) and Grangemouth on trains of dangerous tank wagon loads. A published source (Marshall) suggests these were on the frames from APCM vans, however these wagons were far longer and are reported as new build. They also had one pair of ex LMS brake vans for use as match wagons to move wagons that only had automatic couplings. They were based at Westbury for the many aggregate wagons.
