The Barry Docks were constructed on a lavish scale with the most modern equipment, designed to enable rapid loading and discharge of vessels. Hydraulic power was provided for the operation of cranes and other plant, and the lock gates, and electric lighting was installed, as 24-hour working was in force. After 1898, the Barry Docks consisted of a basin and two docks of respectively. In 1901 the company stated that there were 21 high-level and nine low-level coal hoists with a further eight movable (using traversers) two of which were placed on No. 1 dock. Nos. 1 to 11 on No. 1 dock and 22 to 31 on No. 2 dock, were served by high-level rail tiers and short viaducts and with generally two lines for the laden wagons to a single line weighbridge and two lines from the single line empties weighbridge returns. Low-level hoists on No. 1 dock were numbered 12, then 13 to 18 on the Mole and thence 19 on the Barry Island side of No. 1 dock. Following 1915, the Barry Railway Company established low-level fixed hoists Nos. 32, 33, 34 and Nos. 4 and 5 movable, on the Barry Island side of No. 1 dock. Two earlier low-level hoists, Nos. 20 and 21 were fed from Graving Dock Junction and Caisson sidings area. In 1893 these were numbered 2 and 3 but were removed prior to 1927 and one early map shows No. 18 on the Mole, renumbered 20, 18 being substituted for one on the Barry Island side of No. 1 dock quay where three low-level hoists, Nos. 1, 2 and 3 movable (with traversers) existed either side of No. 19. Most of the 1st-generation high-level coal hoists on both docks were replaced by Armstrong–Whitworth structures capable of more rapid discharge of coal wagons. There had been three high-level movable hoists at the north end of No. 2 dock and close to Nos. 30 and 31 hoists and on one docks plan, these too were referenced "No. 3 Movable" and "No. 4 Movable." Besides other dedicated plots, that area had been used by the US Army towards the end of World War II. None of the hoists remain, and only pictorial records of their format survive. The Barry Railway General Manager, Edward Lake, told
The Railway Magazine: Other provisions for dealing with merchandise traffic have not been lost sight of. Along the south side of dock No. 2 has been erected a commodious transit shed with cellarage and ground and upper floors, and bonded stores, of 500 ft. long and 156 ft. wide. In connection therewith, cranes and other appliances have been provided to enable traffic to be received into the sheds either from ships or trucks or to be loaded from the warehouse into trucks or vessels with the utmost despatch. Close to this building a huge flour mill has erected by Messrs. Joseph Rank, Ltd. Every provision has been made thereat fur dealing with an extensive trade in the most complete manner, and no doubt this will add considerably to 'the future prosperity of the Barry Railway. A modern dock like Barry would not be complete without a cold store. and one has been constructed adjacent to the dock quays, in which frozen meat and other goods requiring cold storage are stored, and the arrangements are such that the Traffic may be discharged direct from the ship’s hold into trucks and despatched to the consuming centres or stored in the cold store with the least possible despatch and exposure. At present the store is capable of accommodating 80,000 carcasses of sheep and other goods, and is capable of being largely extended. ==Connecting to the Rhymney Railway==
