The LNWR Study Group

D1	Open goods wagon - 9in sides, to carry 7tons	The most numerous of all LNWR wagon types with over 20,000 being built between the 1850s and 1909. Early exampled had dumb buffers which were later replaced by self-contained buffers, then the familiar 3bolt type. They were 15ft 6in long but those bult after 1889 were 16ft. Only six survived into LMS ownership in 1923	×
D2	Open goods wagon - 20in sides, to carry 7tons	Until about 1900 these 15ft 6in wagons were the second most numerous type of LNWR wagon with about 14,000 being built between 1870 and 1906. They were virtually identical to the D1 except for having two 11in planks and these also were increased to 16ft after 1889. 453 were taken over by the LMS in 1923. See also D6.	×
D3	Open goods wagon - 20in sides, fall doors, to carry 7tons	A dropsided wagon very much like a ballast wagon (D62), but for general merchandise and without the raised end stanchions. Introduced by 1880. Early examples were 15ft 6in long, but those built after 1889 were 16ft. 71 survived into LMS ownership in 1923. See also D5	×
D4	Open goods wagon - 36in sides, door on each side, to carry 7tons	Another very common wagon, with 15,000 built in just ten years between 1894 and 1903. Very useful for loose goods like coal, or almost any other type of consigment loaded through its drop doors on either side. About 3,600 were still in use at the Grouping in 1923. See also D9.	×
D5	Open goods wagon - 20in sides, fall doors, to carry 10tons	Some standard D3 wagons were uprated from 7tons to 10tons capacity by replacing the axleboxes and journals (8in x 3.75in instead of 6in x 3in). They were probably all 15ft 6in long and around 100 were converted in that way. A few D7 were also converted to this type and about 45 in total lasted into LMS ownership.
D6	Open goods wagon - 20in sides, to carry 10tons	A handful of D2 wagons were fitted with the larer journals (see D5) from about 1886, with more conversions of both 15ft 6in and 16ft wagons between then and 1913. Their total number was probably less than 100 and larger and newer types (D84 and D103) but also the availability of D6, D62, D62a and others, meant these were used less and less, the last being withdrawn during the Great War.	×
D7	Slate truck wagon (fall doors), to carry 10tons	Fifty of these fascinating wagons were built in 1885 for transporting LNWR narrow gauge wagons loaded with slate from Blaenau Festiniog to the coast. Each 10ton D7 transporter wagon could carry three of the small wagons crossways.
D8	Open goods wagon - 22in sides (West Cum), to carry 10tons	Just 50 of these were built in 1877 and a further 40 in 1881, for stone traffic. Allocated to the West Cumberland District, they were early Examples of the 16ft length, rated at 10tons and had doors on one side only! It is not clear when they were withdrawn but some survived into LMS ownership.	×
D9	Open goods wagon - 36in sides, door on each side, to carry 10tons	Built between 1884 and 1907, these were similar to D4 but with the larger axleboxes and rated at 10tons. Some 9,000 were built new, but a lot more were converted from D4, with a population of at least 19,000 in total. Most of which were taken over by the LMS in 1923.	×
D10	Open goods wagon - 42in sides, door on each side, to carry 20tons	These wagons looked very similar to D4 and D9 but were in fact much larger being 18ft long on a 10ft wheelbase and rated at 20tons. Primarily for sand traffic in the St.Helens area (for glass making) others were allocated for limestone traffic in West Cumberland. 150 were built and all but one survived until the Gouping.	×
D11	High sided open goods wagon, to carry 10tons	Just one wagon was built of this type in 1903. Very similar to a D9 and rated at 10tons, it had additional planking on top of the sides and ends, producing a very high wagon which was probably use for empty barrels. The experiment was evidently not a success and within 5 years the upper parts had been removed, converting it into a standard D9.
D84	Open goods wagon, to carry 10tons	The first standard designs built under the new Wagon Superintendent H.D.Earl in 1904 and to the new standard lenth of 18ft with a 9ft 9in wheelbase. Basically an enlarged D9, they replaced the earlier type completely and over 15,000 had been built by 1923.	×
D84a	Open goods wagon, to carry 10tons	This is a late addition to the diagram book and nothing is known about the wagon(s). It could even have been an LMS design. It is assumed that some were built, but how many and what they looked like is completely unknown.
D103	Open goods wagon - 9in sides, to carry 10tons	The last design of standad open wagon introduced by the LNWR in 1909, this 18ft wagon replaced elderly D1s and about 6,000 were built. Many were altered by the LMS to have dropsides (known as fall doors) and used for container raffic, before the LMS introducd their own design for that purpose.	×
