In the mid 1950s British Railways launched a modernisation plan which encouraged fast (up to 60mph), vacuum braked, block trains (common cargo and destination) running between distant terminals. In 1957 Charles Roberts Ltd. launched a new 35 ton (gross loaded weight), vacuum braked tank wagon design. Customers included the ESSO, Texaco, Gulf and Regent petroleum companies. Two versions were built, Class A for highly inflammable spirits such as petrol, and Class B for heavier oils such as fuel oil and bitumen. In later life, some of the Class B tankers were used for loads such as molasses, creosote and water for weed-killing trains.
Typical liveries can be seen in Paul Bartlett and Huw Millington's photographs.
NOTES- This print includes tank ends and top platforms, ladders and filler fittings for 35T Class A or B tank wagons with 7' 3" diameter barrels. The middle support of the top platform should sit on the wagon's centre line with the discharge valve-wheel vertically above the discharge pipe below the wagon's chassis.
- A kit consisting of two complete chasses along with these tank ends, fittings and ladders is available separately.
- The ladders will be quite fragile in this material. Replacement ladders in resilient Versatile Plastic are available separately, or you might prefer to replace them with brass equivalents.
- 35T Class A tank barrels were 25' 2.5" long, including dished ends. If using these tank ends, a 70mm length of 22mm diameter tube is required.
- 35T Class B tank barrels were 22' 6" long, including dished ends. If using these tank ends, a 62mm length of of 22mm diameter tube is required.
- Printed chassis for these wagons are available separately.
- Suitable transfers are available in 3mm Scale from Cambridge Custom Transfers including ESSO Classes A and B, REGENT and FINA, both Class B.
