rowehillmaster Posted September 18, 2018 Share Posted September 18, 2018 .... I am starting the underframe, coupler and socket - to date I have not gathered much information, enough for the basics but would appreciate any details or information and help - thanks in advance, regards Andy 1 Link to post Share on other sites More sharing options...
rowehillmaster Posted September 23, 2018 Share Posted September 23, 2018 .... what style of other bogie / wagon / carriage also uses that style of bearing block - it can't of been a one off just for the Roadrailer - it seems to be rubber mounted ? 1 Link to post Share on other sites More sharing options...

Salmotrutta Posted September 23, 2018 Share Posted September 23, 2018 A great sample of archive film. If anyone is interested in producing the Roadrailer, I would certainly buy a batch. Quick one whilst I've got a spare 5 minutes. Most of you may have already have seen it. The prototype boxes on test. In the film the boxes have already undergone some strengthening work after failing MIRA SMMT testing at Oxford. The bodies cracked and wheel Hubs/nuts failed on their fist road journey whist being driven from Scotland to Oxford. It was also found that in road use the trailers would tip over laterally when stationary on roads with near standard cant, guttering and drainage crowns. In the film the Roadrailer is seen crossing Stebbing Road between Rayne and Great Dunmore. Zip forward to 1' 40". P XmasSmileSmr2.png Edit: B*ll*cks. Should have read through my own post from earlier in the thread before posting. http://www.rmweb.co.uk/community/index.php?/topic/54465-scalecraft-roadrailer/&do=findComment&comment=656938 I see from the film that the road wheels were recessed in the van-the Scalecraft model seems incorrect in this respect. If there is interest in producing Roadrailer models, I would buy a batch. Spiffing film! Thanks for sharing! Tip top! 2 Link to post Share on other sites More sharing options...
RMweb Premium ColinK Posted September 23, 2018 RMweb Premium Share Posted September 23, 2018 That driverless tug in the freight depot made me think of the Faller road system - bury a wire in the road and the vehicles follow it. 1 Link to post Share on other sites More sharing options...
rowehillmaster Posted September 25, 2018 Share Posted September 25, 2018 I now have a full size scan of C & O General Arrangement Drawing 218-R-263 'Road-Rail Van' dated 1954, it is the rounded corner early shape, like the ones that were sent to England in 1958 - but most interestingly it shows the cast rail bogie wheel carriers as used in the English version - in a text I have describing the US version it does mention the completion of the 3 improved, lighter by half a ton, versions in 1959, presumably the pattern of the majority of all the later US production ones we see. 1 Link to post Share on other sites More sharing options...
rowehillmaster Posted September 27, 2018 Share Posted September 27, 2018 There is a photo for sale on e-bay, interesting as it has text upon the rear and appears to be a PSC official photo with a number and date (Sept 1960), the strengtheners look like new additions and it still has the american six stud wheels https://www.ebay.co.uk/itm/ROADRAILER-PHOTO-ARGENTIQUE-VINTAGE-21-x-15-cm-TRAIN-WAGON-SYSTEME-AMERICAIN/382300956925?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D6a35732f97b345bcb35cf5f2790a07e4%26pid%3D100675%26rk%3D1%26rkt%3D15%26sd%3D382300956925%26itm%3D382300956925&_trksid=p2481888.c100675.m4236&_trkparms=pageci%3Af7736816-c214-11e8-84bb-74dbd18017ad%7Cparentrq%3A19781cf11660aada915ebf07fff7ca09%7Ciid%3A1 Link to post Share on other sites More sharing options...

rowehillmaster Posted September 28, 2018 Share Posted September 28, 2018 Just for interest, I now have over 60 photos from the USA of a surviving Railroader - lots of detail that will read across to the UK version and a lot of my uncertainties around the underframe have been answered - here is a small selection. 7 Link to post Share on other sites More sharing options...

rowehillmaster Posted September 28, 2018 Share Posted September 28, 2018 .... have you noticed this is an early 'no side door' version without the strenghteners above the wheel pivot supports ? - it is number 186 (I have some number series information and will check it out) Link to post Share on other sites More sharing options...
rowehillmaster Posted September 28, 2018 Share Posted September 28, 2018 The story of this surviving Roadrailer #186, gets curiouser and curiouser ! - my Chesapeake and Ohio Historical Newsletter Vo. VIII - No. 12 December 1976 states -: The prototype models were built without side doors, to increase the strength of the sides as structural members. However, doors were later added to the prototype Railvans (and all subsequent RoadRailers were built with them) Numbers 170 -199 Date/Builder 1964 C&O Grand Rapids So it was one of the last built ? - with no stiffeners or side door and skids on its undercarriage legs like the prototypes? I have found a photo of #186, in a field near Wyoming Yard in Grand Rapids, Michigan taken in June 1980, but it sits tight between two others and you cannot tell if it has a side door, ? In the Chesapeake and Ohio Historical Newsletter Vo. VIII - No. 12 December 1976 it tells of six sitting in a field at Wyoming Yard in Grand Rapids - same group ? - in that group is number 149, with no side door ! The others in the field are 141, 150, 152, 166 & 185 Number 149 does not exist in the C&O numbering/build list !, it has 150-152 built 1959 by Visioneering Co. Cleveland, and 153 -157 built 1959 by Visioneering Co. Cleveland in the 1980 photo number 149 is of a differing construction / underframe to number 186 and any other I have seen, with or without side doors. The build list does have 115-144 built 1964 by C&O Grand Rapids The Chesapeake and Ohio Historical Magazine July/August 1998 Vol. XXXI states -: the RoadRailers in that Grand Rapids field have all been scrapped, except one which is in the B&O Museum Collection in Baltimore - I have a photo of that and it is number 170 - and that is not in the field in 1980, and it has a side door. I have a picture of number 186, on its rail wheels at Grand Haven Michigan taken in 1987, it has no side door. The earliest picture I can find of it where it is now is 2002 Oh the questions ! 2 Link to post Share on other sites More sharing options...
rowehillmaster Posted September 29, 2018 Share Posted September 29, 2018 ..... I have located the air motor - this is an air motor .... here is the air motor on the Roadrailer .... you can just make it out in this picture of one of the UK Roadrailers, ( i have messed about with the contrast to try and enhance it here is another shot of the US one, note the air reservoir (moved on the UK version to the rear spine piece slope as the additional frame strengtheners are there you can see that here ..... that took some working out ! 3 Link to post Share on other sites More sharing options...
jrg1 Posted October 1, 2018 Share Posted October 1, 2018 Is the air motor maker Ingersoll Rand? They were used on gas turbines as starters for the compressor. Link to post Share on other sites More sharing options...
Porcy Mane Posted October 1, 2018 Share Posted October 1, 2018 (edited) Is the air motor maker Ingersoll Rand? Rotax (on the British Version) Edited October 1, 2018 by Porcy Mane Link to post Share on other sites More sharing options...
rowehillmaster Posted October 2, 2018 Share Posted October 2, 2018 I have not found out the US versions part suppliers - Rotax were selling to the US aircraft manufacturers in the 1950s through their Canadian division, so it could well be the same - I will let you know if I find out different.

rowehillmaster Posted October 5, 2018 Share Posted October 5, 2018 More info - one of the US photos had a makers plate that listed 3 Patents - a bit of searching and digging on the US Patents Office website and each of them is available as a .pdf ! - lots of diagrams on the transfer mechanism, the coupler and the brakes - very interesting - a couple of examples -: 6 Link to post Share on other sites More sharing options...
rowehillmaster Posted October 7, 2018 Share Posted October 7, 2018 I have learnt an awful lot from the patent images and descriptions, I now understand how the ball joint on the front coupler works - at one point I thought the rear receptacle pivoted ! -: 5 Link to post Share on other sites More sharing options...

Go prototypical - a ball on a stem, fitting into a keyhole socket. Pretty much what Scalecraft did - but they used a truncated pyramid rather than a ball. Regards, John Isherwood.

Mr_Tilt Posted October 9, 2018 Share Posted October 9, 2018 So long as the vehicles are nose heavy enough an L shaped rod or bar going through the transom of the leading vehicle, or adaptor wagon, should keep them in contact. If it's thick enough it should look enough like the real thing to be convincing. 1 Link to post Share on other sites More sharing options...
rowehillmaster Posted October 23, 2018 Share Posted October 23, 2018 .... been playing again - as my initial model has the flatter top roof and in the absence of detail, I have made a coloured decal (my interpretation of colours) to recreate the look - what do you think ? 4 Link to post Share on other sites More sharing options...
