During the Second World War a group of seven older clerestory roofed vans was rebuilt with new bodies (type 15a). These formed the pattern for a batch of eight new vans in 1946, which used old coach bogies (type 15b). They were followed by another ten rebuilds of clerestory roofed vans in 1954, which this time had wider bodies (type 16a). Another group of ten new vans used the same design in 1955 (type 16b) but ran on coach bogies. The type 16b vans were numbered 451-460.
