Glorious NSE Posted August 27, 2014 Share Posted August 27, 2014 To my mind the amount of roll looks about right (but as people have said, possibly doesn't give the right feeling of mass) I've got just one freightcar that's capable of a slow roll, it's an old Details West 2 bay covered hopper, with the weight added down low in the hopper bottoms, if you leave both trucks loose on that it will pendulum slowly back to rest - it's still too fast for scale, but oddly it pendulums much more slowly than your average wobbly freightcar.

Gene Posted August 27, 2014 Author Share Posted August 27, 2014 Jeez guys...throwing physics and all around....it's a freaking hobby for pity's sake!!! As the original poster I want to say...it is not my modelling or my video..I did not ask for comments about the video.....I did assume there would be comments.....to those who like it, good on you, to those that don't like it , good on you. To those who are really dissecting the "reality" or " accuracy" or "physics"....good on you too. Me...I think the guy did a credible job within the confines of HO model railroading.....we use 5-finger cranes to put locos and stock on track, we use unrealistic radii for curves, unrealistic grades, compression, most egregious to me are how most locos can seem to run,shunt,stop and start with out loco drivers...very inaccurate.... etc., etc., etc.,. Me...I like what he did, he got it pretty close to some videos I've seen....and I wouldn't try it myself. Cheers Gene Link to post Share on other sites More sharing options...
highpeak Posted August 27, 2014 Share Posted August 27, 2014 To my mind the amount of roll looks about right (but as people have said, possibly doesn't give the right feeling of mass) but the track looks exaggerated. Presumably this is because, in real life, some of the sway comes from the suspension components. I'd be pleased with it, and if he can get the track looking like its bedded into the ballast properly (i.e. nearly under it!) it will look good. Back in the days when I went out to take photographs, you'd always see some cars that were rocking much more markedly than others in the train.

highpeak Posted August 27, 2014 Share Posted August 27, 2014 I suspect both kinds of rock have something to do with joints. Link to post Share on other sites More sharing options...
F-UnitMad Posted August 27, 2014 Share Posted August 27, 2014 Okay time for a laugh... Rough track at Portway Center (O scale). Yes it uses the wrong track - bullhead rail and chairs - yes it's Peco, what I had to hand for a quick layout build. ...and being inspected at TVNAM... Staggered rail joints. Self-guarding Frog/point under construction. normal viewing angle when the track will be in place... not so bad... I'm fascinated by the way self-guarding frogs look "backwards" to normal ones, somehow. Comedy Show over. Link to post Share on other sites More sharing options...

signalmaintainer Posted August 27, 2014 Share Posted August 27, 2014 Although I'm certain the creator of the three-rail layout is rightfully proud. . .Please make it stop!!!! Not you, F-Unit. Gotta admire a guy who's not shy about using bullhead rail and SG frogs on the same layout. Link to post Share on other sites More sharing options...
F-UnitMad Posted August 28, 2014 Share Posted August 28, 2014 Sorry, should've been clearer; the SG-frog switch is for my next project, not the layout pictured, which uses a Marcway & a (slghtly modified) Peco switch, both BH rail. Link to post Share on other sites More sharing options...
F-UnitMad Posted August 28, 2014 Share Posted August 28, 2014 You are more than welcome.However, I wonder if your modelling is lacking a certain something*, * In addition to the obvious 3rd rail. Although it does have flat-bottom rail. Whatever my modelling is lacking that that layout has, I'm quite glad I'm lacking it...!!! Link to post Share on other sites More sharing options...

Prof Klyzlr Posted September 11, 2014 Share Posted September 11, 2014 Dear "Rock n Roll Rails" fans, Just saw this YT of a (HO?) layout, and apart from the switchrail<>stockrail gap,(which I'm sure Andy will pick ;-) ), the "down the barrel" viewpoint seems to show a very interesting form of model "rocking/swaying" which,while visible, does not appear to be anywhere near as pronounced as the OP example clip. Now, whether this is simply "typical HO track laying",(I know my trackwork often ends up a lot more lumpy than I intend, despite best-efforts),or a deliberate attempt to do "subtle rough track" I don't know... However, it does strike me as not so obviously "out of scale" in terms of equipment-rock physics.... Intrigued... Happy Modelling,Aim to Improve,Prof Klyzlr PS also check the P.o.V. in this clip at the 4:30 mark... https://www.youtube.com/watch?v=8PfXiFLjT0s#t=265 Link to post Share on other sites More sharing options...
F-UnitMad Posted September 11, 2014 Share Posted September 11, 2014 I like it. Maybe he should've been going just a tad slower? I'm sure Andy will slaughter it....... Link to post Share on other sites More sharing options...
Andy Reichert Posted September 11, 2014 Share Posted September 11, 2014 I like it. Maybe he should've been going just a tad slower? I'm sure Andy will slaughter it....... The motion looks pretty good to me. The track appears to have been laid very flat in model terms. Just that one foreground slight height misalignment jog (may be a track type change at what appears to be a module joint). The cars are probably on regular rigid trucks with one loose bolster screw and so tightly following whatever the tilt of the track is. Which clearly isn't much at all.
