Product Description

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 a chassis, tank ends and top platforms, ladders and filler fittings for either a single (Choose SMALL option) or a pair of (Choose LARGE option) 35T Class A or B tank wagons with 7' 3" diameter barrels. Basic buffers and coupling hooks are also included.
You will need to supply a suitable length of 22mm diamter tube, rod or dowel to complete.
- 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.
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. Check prototype photographs for ladder positions.
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.
Filing a shallow groove from the bottom of each "W iron" up to the axle recess will make fitting wheelsets easier.
Depending on the wheelsets chosen, the brake blocks and hangers might need some easing with a round file.

Suitable transfers are available in 3mm Scale from Cambridge Custom Transfers including ESSO Classes A and B, REGENT and FINA, both Class B.
