Catweasel Posted April 16, 2014 Share Posted April 16, 2014 Looking at a possible 18" gauge line. Very light rail and 32 mm gauge. Loco to be Yatton Engineering Sylva Springs fitted with radio control. Code 100 rail soldered to 12 mm copper clad sleepers to represent welded track. Very tight curves of course. Photo is of typical point. Link to comment Share on other sites More sharing options...
sir douglas Posted April 16, 2014 Share Posted April 16, 2014 So I see that you've copied from that pdf file on a certain website as well, I've already done the same for a project over a year ago, its a brilliant source. Cant wait to see some modelling of 18". Regards, Sam. Link to comment Share on other sites More sharing options...
rue_d_etropal Posted December 18, 2014 Share Posted December 18, 2014 like the point. I have probably seen where it came from, but would like to know for certain. I was considering designing some 3D printed lightweigh track like this. Link to comment Share on other sites More sharing options...
flexible_coupling Posted December 18, 2014 Share Posted December 18, 2014 like the point. I have probably seen where it came from, but would like to know for certain. I was considering designing some 3D printed lightweigh track like this. You want to be looking at http://www.kbscale.com/ I'm severely tempted to build some 2' gauge stuff soon...

bécasse Posted December 18, 2014 Share Posted December 18, 2014 I have provided detailed plans for modelling 2 foot gauge industrial track panels in 7mm scale in a new topic "Industrial 2 foot gauge track" http://www.rmweb.co.uk/community/index.php?/topic/93803-industrial-2-foot-gauge-track/ Link to comment Share on other sites More sharing options...
rue_d_etropal Posted December 19, 2014 Share Posted December 19, 2014 I am more interested in minimum gauge track, 18in ,15in or 40cm, like this http://s18.photobucket.com/user/stephenbennett/media/Decauville40cm.jpg.html and this I think is the same track,but also shows more http://s18.photobucket.com/user/stephenbennett/media/Decauville40cm_2.jpg.html Link to comment Share on other sites More sharing options...
bécasse Posted December 20, 2014 Share Posted December 20, 2014 Simon Bear in mind that track (be it of 40cm, 50cm or 60cm gauge) set to that sharp a radius was only ever intended for hand operation, although I have seen a "Type 1" point in 2ft gauge used to access a loco shed (so used by 4w locos but not for haulage). Indeed I believe that 40cm track in France was normally only ever used for hand (or possibly cable) haulage. 50cm track, however, was almost the industrial standard (rather than 60cm) in France. I do have a detailed drawing of a LH "type 2" point in 12mm gauge (just over 50cm in 7mm scale) from which the point on my layout at RAMMA last year was constructed and which certainly works perfectly - note that you can't just blow-up/blow-down drawings to suit different gauges as the crossing angle changes, they have to be redrawn from first principles. You are welcome to a copy if you let me know. Link to comment Share on other sites More sharing options...
rue_d_etropal Posted December 22, 2014 Share Posted December 22, 2014 Decauville always reconned 40cm gauge was not suitable for loco haulage, but there are a number of industrial lines around which have managed , just. There is also the brick museum railway in Brittany, which is mainly for passenger use, so suspect no sharp curves, as tide would be even more uncomfortable) Sharp curves in reality on any gauge would probably not be suitable for loco haulage, but for models , there are a lot of sharper than prototype curves in all scales and gauges. Something I might do is have motorized wagons, and have a figure somehow 'pushing' the wagon. I used standard Peco Setrack on my APA module at RAMMA, but am investigating something for a new challenge, and possibly spin offs using 3D printing. I seem to remember some very tight curves on some of the models at RAMMA. Link to comment Share on other sites More sharing options...
sir douglas Posted December 22, 2014 Share Posted December 22, 2014 theyve had tight radius 2ft track down the mines and used by battery and flame proof locos Link to comment Share on other sites More sharing options...
rue_d_etropal Posted December 22, 2014 Share Posted December 22, 2014 Quite often track was not even curved, just a series of short straights, and then there were the single blade points. It was something like the mining operations I as thinking of, with some type of (freelance) battery trammer . I have printed of and resized the point above, and for 16.5mm gauge it would be about 6in radius. Would like to see others in the range. I am sure I have seen them in some document online. It is actually bigger radius than I expected, so I will probably continue with my 10cm ones. If they work Ok then OK, but otherwise I will up the radius, or use some converted r2r points(Jouef 32cm radius) for initial project. That point drawing, has, though, shown be size of steel sleepers.
