Manufacturer description

The pressure discharge bulk powder wagon abbreviated to Presflo was developed in 1954 to efficiently transfer and transport cement and other powders. The wagon had a capacity of 20 tons (later increased to 22 tons) and was gravity fed from the top and discharged under pressure via pressure hose and valves from one side of the wagon. Five different factories were involved in the production of the total 1920 Presflo cement wagons produced between 1955 and 1961 and so successful was the design that they were only finally withdrawn in 1987. Several Presflo wagons survive into preservation

The Dapol model of the Presflo features:

• Highly detailed body moulding

• Profiled wheels

• NEM pockets with self centring couplings

• Accurately applied livery

Catalogue listing

Model details

Dapol Presflo Amalgamated Roadstone (ARC) is a OO gauge model of a pressure‑discharge bulk powder wagon. It is supplied in the Amey Roadstone (ARC) livery, incorporates NEM pockets with a tension‑lock self‑centering coupling, and has a minimum curve of radius 1. The model carries the manufacturer part number 4F‑035‑100 and represents the era of the British “Big Four” railway companies (LNER, LMS, GWR and SR).

The original Presflo wagon was introduced in 1954 to allow efficient loading, transport and discharge of cement and other powders. It had a capacity of 20 tons, later increased to 22 tons, and discharged under pressure from a valve on one side while being gravity‑fed from the top. A total of 1 920 wagons were built between 1955 and 1961 by five different factories; the design proved so successful that the wagons remained in service until their final withdrawal in 1987. Several examples have been preserved on heritage railways.

The Dapol model is noted for its highly detailed body moulding, profiled wheels and accurately applied ARC livery. It also features NEM pockets with self‑centering couplings, replicating the appearance and operational details of the original Presflo wagon.
