The Diagram 1410 van was the most numerous ventilated van built by the London & South Western Railway (LSWR). Construction began in 1885 and more than 1,000 were built, with various detail differences introduced over the lifetime of the vans. These characterful vehicles feature outside framing, sliding doors and were built with a reduced height when compared with vans built later on. In addition to its own fleet, the LSWR also constructed ten vans for the Somerset & Dorset Joint Railway (S&DJR). Curiously, the same Diagram number was assigned to this build despite the obvious difference – the lack of vents on the ends. Finished in S&DJR Grey livery, this model is fitted with a single sided brake, Panter axle boxes and plain tapered buffers.
