These bow-ended carriages were built to two diagrams in 1923 and 1924 respectively, differing only in that H26 had Pullman gangways and buckeye couplers. They were rebuilt during the late 1930s and received modern integral sliding vents in place of the toplights and H26 received scissors gangways to match H29. The kit depicts this rebuilt style. One (9574) received 6-wheel bogies; please specify when ordering if you wish to model this carriage.
