Rites of Passage for a Model Railway - 9: Low-Sided, Flat and Bogie Freight Stock; Engineers' Department
Wheels of industry - models, and the real thing (not the canned, fizzy variety)
Special loading and tall orders
Low- sided wagons came in many forms. Some were used for transporting containers, some with shackles for machinery and others were tailored - with ribbed decks - for carrying steel plate to ship-building yards or bridge decking for civil engineering. Then there were machinery wagons to transport tractors and combined harvesters from the manufacturer to the supplier. Further, well wagons transported large cylindrical elements such as ships' boilers and bridge bascinets to support the superstructures.
Other special purpose vehicles carried plate glass, and trolley wagons took loads that might otherwise be vertically 'out of gauge'. Pulley wagons carried loads that were suspended within the wagon body and performed a similar function to that of a well or trolley wagon. Early in the 20th Century special wagons were built to carry armour-plating for ships. Drop-sided wagons enabled the sideways loading and unloading of machined goods for civil engineering and shipbuilding that might be too heavy for railway cranes. Trestle wagons enabled out of gauge loads to be carried diagonally, like steel plate for ship or bridge building that would otherwise entail parallel lines being closed because of width problems. And then there was the Cantilever Set that allowed bridge sides to be transported by rail to sites. The biggest challenge was the movement of boilers to power stations. A special set of wagons was engineered from other components to carry these, at a maximum loading capacity of 290 tons and this can be seen at the Shildon site of the National Railway Museum. It consists of eight large bogies and 'bridging' units made up from girder sets and heavy plating to carry the tall turbines lengthwise and was built at the Ashford Works of the Southern Region in the 1960s - see below in the reading list, BRITISH RAILWAYS WAGONS.
Robert Hendry's range of wagons colour photographs is extensive in this handy reference work. The era is British Railways, the wagons are of divers origin dating back to pre-Grouping in various stages of repair and livery. What is really useful is the colour tonal range (allowing for what time of day images were taken). Handy for weathering information. Volume 2 takes you into the diesel era of British Rail as the system became known from 1966.
The real thing and the model
Late in the 19th and early in the 20th Century containers were already in use for moving furniture for ease of handling, although the handling equipment had not kept up-to-date. The containers, built of vertical planking, had to be loaded with old cranes and manhandled into place from the wagon to the horsedrawn carts - later lorries - but gradually handling improved.
By Nationalisation containerisation was much more widespread, with different types of container available for different types of load. There were open containers with twin bars to maximise lifting; there were smaller containers that could be fitted side-by-side or end-to-end; and there were the conventional containers - that could be loaded with goods from house furniture to frozen animal carcases - to be taken door-to-door, and stored in customers' yards ready for collection. But they could not be stored in stacks yet, like modern containers. At first containers were privately owned but later the railway companies built up stocks for their own use.

Low sided, machine wagons and tank flats etc
The North Eastern and Midland Railways boasted the greatest range and size of fleets for the movement of heavy freight, then the LNER and LMS took over in the 1920s. The depression helped no-one but in the late 1930s, before WWII, traffic picked up until the weight of responsibility almost broke the railway companies' backs. Bust-to-boom.
A great element of goods on low-sided wagons took the form of machinery and steel plate. In the manner of machinery there were army lorries, tanks and half-tracks as well as mobile guns and assorted field ordnance. The War Department had bogie tank flats built, with jacks that could be screwed down to allow the tanks to trundle off without the wagon trundling off in the opposite direction! They were also fitted with vacuum brakes for faster running. Later many of these tank flats were converted to bogie bolster quads - four sets of bolsters - for transporting steel girders and the like. Machine wagons already existed for the transport of farm machinery, and in WWII these could be used in block trains for moving military road vehicles. Plate wagons were built by the score for the LNER and LMS chiefly for moving steel plate to the shipyards on Clydeside, Tees-, Tyne- and Wearside in the North East and Barrow-in-Furness and Merseyside in the North West. Added to these were four-wheeled twin bolster wagons for transporting shorter girders, rail or twisted steel lengths to be used in concrete bridging or buildings as well as 'steel mats' for bigger concrete surfaces. There were older single bolster wagons that were built to carry longer steel products where a single vehicle body length might be asking for trouble. They may also have been used for carrying long timber (tree trunks) to sawmills. 'Low-fits' could be put to many uses, and there were single plank brick wagons (as well as bogie brick wagons that were higher-sided for large loads).

Low sided and flat wagons
Departmental stock is largely ignored, but necessary for the smooth running of a railway. Many were downgraded from revenue-earning service as they wore out and served as 'internal user' (IU) vehicles that were probably shunted within loco or goods yards for tools and the supply of grease or other lubricants.
Then there were the sleeper wagons and flat wagons for moving whole, complete made-up sections of rail that would be lifted off the wagon by one crane and lowered into gaps left after another crane had lifted a previous section. This operation was carried out 'in tandem' and featured in a video recording titled BEHIND THE SCENES from Fast-Line (I still have a video recorder, but it may well have been translated into DVD form by the same people). The same video contains a section on limestone quarrying for railway ballast, ballast production from furnace slag at Lackenby (steel works) on Teesside, maintenance of the line and so on including creosoting sleepers at Hartlepool. There is even a section featuring a namesake of mine in the 1930s, who was District Engineer around Hartlepool.
Let's not forget cranes - brakedown, line maintenance and goods handling. The latter could have been either small mobile ones or yard features. And there were ballast ploughs and ballast wagons. Some of these last-mentioned were specialist vehicles that distributed the ballast outside the rails, others dropped the ballast only between the rails and the ballast ploughs were often converted brake vans known as 'Sharks'.
From the 1950s Departmental stock was especially built for the task and took the names of sea fish such as 'Dogfish', 'Grampus' and 'Sturgeon'. There was a 'Mermaid', but I won't go into that!
