frogster Posted February 10, 2017 Share Posted February 10, 2017 I recently was given a box of model railway magazines, whist reading a the august 2004 of railway modeller I came across an article on an Atkinson-Walker Geared steam locomotive which sparked my interest, it seemed to be a fairly unique locomotive, it also featured a model version created by the author Neil Burgess made of brass and technical drawings. As i am currently building a small industrial layout and thought that this locomotive would be an ingesting locomotive to run on the layout, so I started making one to be 3D printed in 4mm scale. . I would be greatly appreciated if anyone might have some information on the locomotive or more pictures of it since information on the locomotive is limited. 3 Link to post Share on other sites More sharing options...
Arthur Posted February 10, 2017 Share Posted February 10, 2017 One was trialled on the former Manchester Collieries system, in fact I think the photo you posted might have been taken there. There is brief mention of it in one of the books I have on the system. I'll have a look but I'm not sure that it will add much. Interesting project. 1 Link to post Share on other sites More sharing options...
£1.38 Posted February 10, 2017 Share Posted February 10, 2017 Apart from a narrow gauge design for Singapore, Atkinson Walker only built a few prototypes, including several narrow and standard gauge one-offs. There used to be a comprehensive article on the Web, but it seems to have disappeared recently. Photos are very rare. This page has photos of two of the standard gauge variants http://www.gracesguide.co.uk/Atkinson-Walker_Waggons The book on the Clogher Valley Railway by Patterson has some information on the loco built for that railway, including a cross section of a loco from an Atkinson Walker brochure. This page gives 2 photos of your loco, including the one in your post http://www.irsociety.co.uk/Archives/49/PP_49.htm 1 Link to post Share on other sites More sharing options...
Arthur Posted February 10, 2017 Share Posted February 10, 2017 The photos on the IRS link are those in Geoff Hayes' book on the Manchester Collieries system (Bridgewater Collieries became part of Manchester Collieries). 1 Link to post Share on other sites More sharing options...
RMweb Gold phil_sutters Posted February 10, 2017 RMweb Gold Share Posted February 10, 2017 (edited) In an archived RMweb thread there is this "More info. on Aktinson-Walkers can be found in 'Vertical Boiler Locomotives', Rowland Abbott, Oakwood Press."

frogster Posted February 11, 2017 Author Share Posted February 11, 2017 Thanks for the information so far, I have just made major changes to the design within the last few hours and have opted to instead of designing my own chassis for the locomotive i would use a bullant gozunder unit with a small machima 1020 motor hidden inside the boiler, but due to this i have had to make the boiler slightly over size (added about a mm all round) to fit the motor), at the moment it will have a 15:1 gearing ratio but i hope to improve that with some tricky gearing hidden in the part of the boiler that sticks out under the body. The chimney will be made from 4/16" brass tube, which can also hide the extra little shaft from the motor where you would normally fit a flywheel. I hope to print off a test print by Monday. 1 Link to post Share on other sites More sharing options...
rue_d_etropal Posted February 11, 2017 Share Posted February 11, 2017 one suggestion, I design similar models with roof attached. I design an interior which then fits in, and then build a sub base to fit motor chassis. Reason being that we tend to look at these models from above so that is the most important part to get looking right. 2 Link to post Share on other sites More sharing options...

Reason being that we tend to look at these models from above so that is the most important part to get looking right. Interesting suggestions, I'm new to this sort of project, but i did have the roof attached but after some research and understanding of the 3d printer I will be using a decided to remove the roof since it wouldn't be able to be supported well enough during printing, and with the interior the only thing I know about is the general size of the boiler, I have no idea what else was inside the loco. I have also assembled the body as such because the floor wouldn't be thick enough without the lower chassis mounting area because i wanted to hide the motor as much as possible which meant using a specific chassis that would mess with the floor if there was any separate sections between the two. But thanks rue_d_etropal for the ideas, I will take them into account if I make a model of different loco. If anyone has any information concerning the interior of the prototype that would be greatly appreciated Link to post Share on other sites More sharing options...
RMweb Gold phil_sutters Posted February 11, 2017 RMweb Gold Share Posted February 11, 2017 There is a fascinating, but very expensive series of seven (I think) volumes of 'A History of the British Steam Tram'. I bought vols. 3 & 6 very reasonably in a local second-hand shop, but some volumes are on the net at £50+. There are no AW locos in the volumes I have, but there is a huge range of similar steam trams - some quite bizarre. I can't help thinking that there are potential models lurking there. 1 Link to post Share on other sites More sharing options...

If anyone has any information concerning the interior of the prototype that would be greatly appreciated oneof the reasons I like Shapeways, is that I don't have to worry about creating the supports. also, contrary to what some think,WSF is alright for this type of model, For my WW1 Simplex, I was able to design a motor cradle which just cliped in. With any less flexible plastic this would have been more difficult. Link to post Share on other sites More sharing options...
frogster Posted February 23, 2017 Author Share Posted February 23, 2017 Over a Week late I have finally got the prototype print completed, it worked out great except for the fact that i realised that my hole in floor was off centre. I was going to upload some photos but they were too large, they will come later. Link to post Share on other sites More sharing options...
