Difference between revisions of "ICI 19052 Bogie Steel Hopper Wagon"

Construction

The wagon is of all steel construction. It is mounted on diamond frame pattern bogies of 6 ft. wheel-base, 26 ft. between centres, and is equipped with automatic vacuum brakes in addition to hand-brakes on either side, the power cylinders being fixed at each end of the frame and applying four blocks to each bogie.^[1]

The hopper is 29 ft 6 in long by 7 ft 11 in wide at the top, decreasing to 18 ft 3 in by 2 ft 1.5in at the bottom, with a depth of 7 ft 11 in. This gives has a capacity of 1,230 cubic feet, equating to a load variously quoted as between 43.5 tons and 48 tons.^{[note 1]} The load is discharged between the rails through two bottom doors, each having a clear opening of 7 ft 7.5 in by 2 ft 1.5 in. These doors are fitted with a patent opening and closing device, the load inside forcing them open when they are released and at the same time compressing the springs that control them. On reaching their full-open position the doors are held in a catch until the load is discharged; on being released the energy stored in the springs forces them back into the closed position. The whole operation of releasing, discharging, and reclosing was said to take less than 2 minutes^[1].

Service

The 8FThe British Railways system of classifying steam locomotives by power using a number from 0, least powerful, to 9, most powerful, followed by either F for freight, P for Passenger or MT for Mixed Traffic.'s tractive power made it possible to introduce large vacuum-braked bogie hopper wagons designed specifically for this traffic. For something like thirty years the 8FThe British Railways system of classifying steam locomotives by power using a number from 0, least powerful, to 9, most powerful, followed by either F for freight, P for Passenger or MT for Mixed Traffic.'s remained closely associated with this service; other motive power included Super DAn LNWR 0-8-0 goods engine's and Derby 4's although class 9FThe British Railways system of classifying steam locomotives by power using a number from 0, least powerful, to 9, most powerful, followed by either F for freight, P for Passenger or MT for Mixed Traffic. locomotives were never used on these runs before diesel traction replaced the 8Fs. After steam ended, the rakes of the wagons remained in regular use on limestone traffic, initially hauled by Class 25 type 2s and latterly by Class 37 type 3s.^[1]

Preservation

Although there is no record that 48773 was used to haul ICI mineral traffic, owning group the Stanier 8F Locomotive Society decided in 1993 to preserve one or more of the wagons in view of their close association with the 8FThe British Railways system of classifying steam locomotives by power using a number from 0, least powerful, to 9, most powerful, followed by either F for freight, P for Passenger or MT for Mixed Traffic. class, none having been saved for preservation at that time.^[1]

Negotiations with the SVRSevern Valley Railway secured the agreement for the Railway to accept two wagons if the 8FThe British Railways system of classifying steam locomotives by power using a number from 0, least powerful, to 9, most powerful, followed by either F for freight, P for Passenger or MT for Mixed Traffic. Society could obtain and transport them, and subject to inspection of their running capability and general condition. The two selected wagons were purchased from Buxton Lime Industries Ltd. on 8 November 1993. Delivery of both wagons was scheduled to allow them to make an early appearance in a photographic freight charter on 3 May 1994 but an extended commitment of three Alleleys' low loaders prevented this. Delivery was re-scheduled for 7 May; in the event 19129 arrived on the day but 19052 was delayed by various technical and administrative problems and finally arrived at Kidderminster on 16 May.^[1]

The 8FThe British Railways system of classifying steam locomotives by power using a number from 0, least powerful, to 9, most powerful, followed by either F for freight, P for Passenger or MT for Mixed Traffic. Society had chartered two inspection saloon specials for their AGM on 18 June 1994. Having failed to make the earlier freight charter, they had hoped to attach the wagons so they could be displayed in use. However it transpired that to do this, the hoppers would need to be accompanied by a brake van, requiring repetitive shunting during the day which could not be accommodated. By that time, one hopper was at Kidderminster, largely concealed behind visiting diesels and other stock in the yard, and the second was at Highley.^[1]

After arrival both wagons remained in "as received" condition for many years, latterly stored on the Stourport Triangle.

  19052 in April 2015, unrestored

The Society's Board planned to restore the older wagon, 19052, in the experimental livery of 1936/37. Smaller lettering for 'I.C.I.' was used on pre-war hoppers; a very much smaller 'Ltd.' was not added after late 1937.^[1] Cosmetic restoration finally took place during 2020.

• 

  At Kidderminster following repainting, November 2020

The Board also decided that the later wagon (BR TOPS no. 19129, no 3329 built in 1952) was to be restored in I.C.I's. post-War colour specification at overhaul, all grey with black wheelsets and white lettering.^[1] However this still remains an ambition as of 2023^[update].
