Is there a solution already for giving the angles of the bank for the C Track curves, i.e. 24130 curve has a bank of say 5' and the 24230 curve has a bank of 4.5' , etc. Do you know what I mean ? Does the gradiant come into account ? I'm using 3% gradients on my layout. I should know this information as I studied mathematics at university, but that was 40 years ago and now I'm lucky if I can spell mathematics !!! Anyone with ideas ? |
Take it easy . . . . or any other way you can get it !!!!

I don't use banking on curves. It causes more problems than it solves!

Thanks for that advise Ray, the more I think about it the more the problem escalates - exponentially !!! Greg |

Wasn't there a thread on this subject within the last 6-12 months? Personally I'd go for the simplest solution - be like Ray and not have banking on curves. |

Greg, I think Cem, from Turkey has his M track banked. It can be done with ramps, but how fast do you want to run trains? I don't think it's necessary. HO Locos. do run way faster than average scale speed. The first time I ran my Fleischmann ICE (years ago) it flew off the track. Lucky I had carpeting beneath the layout then. They make the awesome ICE T that really does tilt on curves, and the pantograph stays in contact with the overhead power line. It comes in a/c 3 rail also. (Not trying to sell Fleiscmann for them)

I have superelevated a few sections of track for operational reasons, however for my next expansion I intend to do it as part of the design. I have been observing the real thing and have come to the conclusion that it is necessary to make the model look right. I plan to shim the cork roadbed I place under my K track in order to accomplish this. As I said, I have done it in a few spots this way where I have experienced derailments with a few trains (specifically my VT08 going through a section of R1 curve coming off a slight upgrade at the north end of my station)

Hi guys,
Yes, I have my curves banked. With m track it is easy. A friend of mine made milder banks with his c track and it was very easy to do too. He just put 2 mm. cardboard under one side of the tracks, the result was just great.
I think banked curves add a lot of realism (and some functionality) to a layout. For me they are quite indispensible.
To anyone who'd like to try, I suggest to try it out with 2 - 4 mm cardboard (screw down the track and run a loco over it) and if you like it just go for it.
Cem. |

The superelevation is not to allow the models to run faster, nor should it cause any additional derailments. It is done for the aesthetics only and it does make the trains look very realistic. For HO scale all that is needed is 1mm of additional height. |

Dale, I agree that my interest in this is aesthetic, however I did use it as described above to solve a derailment problem on rigid long wheelbased units such as the VT08 and my BR610 where I had a small vertical inflection entering an R1 curve section. Worked great for that. |

Scale or not, but in the real world superelevation never exceeds 2-300 mm wich to H0-scale would be less than 3.5 mm. For looks and practical reasons I sugest 1-2 mm regardless of the radius, and actually less in smaller radius since you do not want to risk long heavy trains to fall in to the curve. |

Wow, great to hear both sides of the story - to bank or not to bank ? Thanks for the tip on banking the C track with about 1to 2mm. What I'll try is to use some foam adhesive tape and screw the track to base. By using foam tape it will easily bend around the outer curve of the track. I'll let you know how it turns out. |

A little bit of curve banking solved a problem I had with the GG1 on ascending/descending curves (~4% slope).
I first noticed that on ascending a curved track section (R2), the GG1's front wheels of the front truck jumped the rails. On a descent, this also occured and sometimes the front wheels of the rear truck also jumped. The jumps did not occur at a track junction but partway along the track. This didn't happen with other locos (steamers - BR86 and BR50). I also had no problems with the GG1 on unbanked level R1 and R2 curves.
