L.M.S 4-6-0 5MT Black 5 Atlantic specification Atlantic cost

Select technical detail to view a description of our steam kit design.

       This class of locomotives was intorduced by the new CME of the LMS, Sir William Stanier in 1934. Over a period of years a total of 842 were built.As with any design built over a long period there is an inevitable proess of development ant the Black 5 was no exception. The obvious visible changes were for the straight throatplate 2A boiler to the sloping version 3A and between Walshaerts, Stephenson and Caprotti valvegears. The boiler dome and water feed boxes also varied. The tenders used were all 7ton 4000g Stanier roll top, early versions being riveted and later all welded.

        Liveries started with the 1928 style fully lined black and went through various black based schemes with variations  in lining and lettering. Four of the class were painted in green for a short period. Only four of the class received names.


       Our model is based on the Walshaerts valvegear prototype with either the 2A or 3A boiler. In common with our other designs, the working valvegear will be a robust, slip eccentric, protected between the frames. The outer Walshaerts valvegear will move in a prototypical manner but not be functional, what has been referred to as ‘Bullshaerts!

 There is a book in the ‘Locomotives in detail series’ No2 by Jennison & Clarke published by Ian Allen in 2004 which details the variations of the class.


       These kits produced for those whose machining facilities or skills are limited or whose modelling time is at a premium.

          The boiler is built, tested and certified. The cylinder units come as a ‘loose assembly’ with pistons and valves in place ready for you carry out the final assembly and seal it up. Items such as hand and axlepump bodies are pre assembled. The kit includes  laser cut steel items, etched brass components, all machining done, pressure gauge, screws, nuts, rivets, ‘O’ ring seals, springs etc. to complete the assembly.

           You will require a bench and vice, some hand tools, a drilling facility (which could be an electric drill on a stand) and a small gas torch for soldering. The work includes bending sheet metal, drilling piloted holes out to size, tapping threads in holes ( in many cases nuts could be used instead), soft and hard ( silver) soldering of small items.

           The model making hobby is littered with part built projects which have been abandoned because the modeller has hit a problem. Included in the price are two hours of our time, a ‘get out of trouble’ service. It could be advice on the phone, a practical soldering training session in our works, correcting a mishap or setting valve timing. Apart from phone calls, a modest charge will be made for time spent over your two hours.

          We can also supply replacements for individual components providing they are returned for us to identify. For etched items there will be charge depending on the size. Whitemetal returned with stamped addressed packing are free. Laser cut steel may be a problem as there are minimum order quantities involved and we shall only order a limited number of spares.

           The Construction  Guide comprises over  30 pages of photographs, exploded diagrams produced on 3D CAD and text, together with identification diagrams and drawings. It takes you through each stage, including jigs and methods, settings and adjustments, finishing with operation and use.
