Comments: |
Some BDO were vacuum-piped to become BDP, and some BDV were air-piped to become BDW. It is likely that some BDO were vacuum-braked to become BDV. Many BDO/BDV/BDW were modified as BSW, JMV (later BUV) and JYV. Others were transferred to departmental use as YNV, YNW, YRO, YSW, YYR, YYV, YYW etc. BDAs were rebuilds, using wagons from most of the earlier lots. Many BDAs were converted/recoded to BEA, BFA, BMA, BTA, RSA, YAA, YNA, YVA, YXA and YYA.
