[@nigelericogden3200]

Indeed !!

[@welshdave5263]

So, this is the translation...

[@Steamerthesteamtrain]

Usually a loco with wheels closer to each other can handle tight curves, the drawback to a shorter wheelbase is hunting oscillation happens more on it vs a longer wheelbase. Also you should've done the minimum radius for coupling since some yards can have engines like the Pecketts and SECR P class and little space.

[@davebell4917]

Yards also have the problem of the points. I suppose somebody making their own could try to build a shorter radius version. I remember seeing very old articles about that, and I think you would need some purpose-made jigs to bend the rail, Also, the materials would matter, but steel. nickel silver, or brass? Would the bent rail need annealing? On real railways they use gauge widening on tight curves. Partly it reduces the side wear on rails and flanges. Because of the wheel profile, there's a slight taper, it can also affect wheel slip, but I look at the math on that in the research papers I found, and I get a headache.

[@SamsTrains]

Yeah that's right, thanks a lot for the info! I will have to try this some time with 0-6-0s! :D Thanks for watching, Sam :)

[@RichardKuivila1947]

x-8-x locos have too many flanges on all of those drivers. Front pair and back pair ONLY, works.

[@LordPhobos6502]

Similar story - 230mm curves for my model trams. Some locos will still make that curve too :p I used a laser-cut stencil to make the curves on soldered PCB sleepers, with room gor transition curves... I'm so happy with the trackwork :)

[@CrumpledSandwich]

@@LordPhobos6502 I had a wooden track setter laser cut for me which sits between the flexi track rails. I had two made actually with the correct spacing for Hornby tracks so the ends of the curves met the straights and points correctly. you can run old Hornby bo bos on the curves and I'm currently shortening a bubble car.

Greetings from America! I liked this experiment quite a lot, it reminded me of my grandfather's stories of his old workplace in St. Louis Missouri. He worked at a boiler fabrication plant and they had rail lines running inside the building to help transport their work. Many of the curves were so tight that only a little two axle loco would run on them and the freight cars (wagons you call them) would squeal as they went around the curves. Good memories, keep up the good work, I'm a huge fan of British steam locos. Cheers!

Back in the 1980's there was a train set that would do just that. I believe it was made by Tyco. You would build most of the layout on the level but 1/2 half of an oval would extend vertically off of the table. It was advertised going up a wall to support the force exerted by the train. A friend of mine had one and I remember it working fairly well but the train had to be run at near full throttle. If you find one or remanufacture one I would love to see the video.

1) I think that you might want to let Hornby know of your discovery , Sam... as this is genuinely impressive. Perhaps 0 Radius and -1 Radius could be the new minimum for UK HO/00 gauge layouts! 2) Perhaps this test could be redone with 0-6-0 tank and tender engines , with the 0 Radius and -1 Radius curves?

Thanks mate - it would be awesome to see Hornby release say an industrial train set with ultra tight curves - could open up a new market there! Great idea - I should really have tried other engines on it! Thanks for watching, Sam :)

This was a great video Sam I liked the reappearance of the older smokey Joe. Can't wait for more videos.-Rilian.

Hi Sam. Great fun. I did, some years back, have an exhibition layout "Yarmouth Quay" based on the Great Yarmouth Tramway. It was 2ft by 4ft with 8ins radius curve, inset into the road. Admittedly the track was all hand laid and there was some(?) gauge widening! But a Mainline 03 could do it with all six wheels flanged. Buffer lock? Yes hand knitted wire couplers, fully automatic, ex office paper clips provided the wire. The layout did many shows over five years before being sold on. Even went to the Great Yarmouth show once....

Thanks very much Andrew, that sounds fantastic - 8 inch curves must have been very extreme, great to hear it turned out well though!! Thanks for watching - Sam :)
