Now for more bad news. You dont say what scale you are using.

Operation on 15 radius with anything larger than an 0-4-0t and a few ore cars was an iffy proposition.

Minimum curve radius model trains coloring pages. Minimum radius on a 0-6-0 and larger is determined by play between the flanges of the front and rear drivers and the rail head along with the lateral movment flange clearance of the center drivers unless center drivers are blind at which point the engine is calculated as a long wheel base 0. For bogie vehicles the AMRA standard used 3x the length as the recommended minimum radius. Therefore the rail to rail height should be about 4 inches min.

They will make it through but they wont look prototypical. I would greatly consider 3 14 inches minimum. NMRA classic height standard is 3 132 and modern height standard is 3 532.

For boys and girls kids and adults teenagers and toddlers preschoolers and older kids at school. 30 inch is a nice mid way between 24 inch and 36 inch radius curves. Heres the specific humble pie incident I refer to.

Super coloring - free printable coloring pages for kids coloring sheets free colouring book illustrations printable pictures clipart black and white pictures line art and drawings. Minimum radius on a 0-4-0 is determined by play between the flanges of the drivers and the rail head. If you have one curve in a wye that is 15 inches but the rest of the mainline uses 18-21 inch curves you still have a 15 inch minimum radius curve on.

Typical HO passenger cars dont feel comfortable on anything less than about 30 radius. Yes 15 radius has been used successfully and there was even a time when 15 sectional track was offered commercially. If all you want to do is run trains and your not worried about the look then use 9 inch radius for better looking stick to 12 or 16.

All my locos steem and diesel 2-8-2s 4-6-2s 4 axle 6 axle and 80 passenger cars run smoth through this 26 curve but a 4 axle RDC gets to one point of the curve and it slows - sounds like grinding and then proceeds through If I run oit at a slow speed to gets. If appearance is the only concern it should be possible to use 24 radius curves on the front of the layout and 18 curves for the rear of the layout and still fit on a 4 x 8. We feature beginner and advanced help on all model railroading scales including layout track plans model railroad product reviews model train news and model railroad forums.

To figure the benchwork width needed one must add the curve diameter 2 times the radius the track width and 2 times the safety margin to the edge of the benchwork. Sharp curves look toylike and contribute to operational problems. Broad curves enhance the realism of a model.

Ive never tried this nor have I even heard of anyone doing it but I might give it a go on my next layout. The following are the minimum DIAMETER of a circle of track recommended for a given locomotive. Diameter Versus Radius.

Here I go again. Model Railroader is the worlds largest magazine on model trains and model railroad layouts. For example Kato offers 85-inch radius curves and the Japanese manufacturer Tomix offers N scale minimum curves of 103 mm radius or 4.

Last year the Australian Model Railway Association AMRA adopted a minim radius standard based on a series of formulae. Looking for help when I cant figure it out. We feature beginner and advanced help on all model railroading scales including layout track plans model railroad product reviews model train news and model railroad forums.

The smallest radius for a curve I would be tempted to lay would be a 24 inch radius but only if it was absolutely necessary as others have said the larger the curve the better any thing above 24 inch radius would be suitable. Model Railroader is the worlds largest magazine on model trains and model railroad layouts. Your spacing of 2 12 inches is very tight.

Minimum radius for a prototype NKP Berkshire works out to about 39-40 radius in HO and that means the tightest curve allowable. 4 inches height would require a 4 2 200run 31416 2 318 inches radius. The RADIUS is half the diameter.

These are recommendations by the manufacturerimporter. The nominal minimum safety margin is determined by the minimum clearance so that trains wont derail but obviously its much safer if we provide at least 3-4 outside the track so that derailed trains dont fall to the floor. An excellent article that confirms the assumptions used in the AMRA standard are valid.

The rear curves could be obscured by scenery and buildings etc. Find manufacturers who offer N-gauge track curves that are tighter than the 11 inches most enthusiasts view as the minimum radius for realistic modeling. 30-36 is considered a nice broad radius for big articulated locomotives or things like 85 passenger cars or auto-racks and whatnot.

Radius depends on what size of locomotives you want to run--typically the smallest size most people like to use is 18 radius but 22 or better is recommended for anything larger than smaller locomotives and the bigger the radius the better the curve will look. Any Berk negotiating that curve would do so at restricted speed. Eighteen inch radius usually requires small equipment and care in track laying to be sure the curve is smooth and consistent.

Now please note that I didnt say that you couldnt use smaller turnouts and curves. As an example if you want to run all locomotives from large steam to any diesel all passenger cars and all freight cars the RP-11 minimum requirements would be a number 7 turnout with a 40 radius in HO or a 215 radius in N scale.
