Since the M.R.W.A. opened the only vans it had owned were the fourteen B class 6 ton vans. 

In 1914 two new BL class vans (272 and 273) were built using parts of written off F class four-wheeled brake vans. Unlike the earlier vans they had louvres in the top half of the sides. They were also 16'-0" long unlike the 14'-0" B class. A further pair (184 and 191) were built in 1915 using parts of the B class vans with the same numbers. No more were ever built and in 1932 this class of four vans became BL841-844. They were written off in 1964 and not taken into W.A.G.R. stock.
