The GWR traffic department made extensive use of the gangway fitted Siphon G ventilated milk vans for carrying passenger luggage, parcels and pre-sorted mail by regular passenger trains services and by the network of dedicated parcels and mail trains. In the mid 1920s a revised design of Siphon G appeared with inside body framing, the external vertical planked body now presenting a much more pleasing appearance. Vehicles to this basic style continued to be constructed into the early British Railways era, with the last being withdrawn circa 1980 having been used as newspaper sorting and packing vans, taking the daily national papers into the West of England.
