Another one of my obscure questions... I have built a test/ photo plank. It has a 10 chain curve with checkrail. To make it fit in the required space it doesn't have a transition zone- but it's for photos/test not running. I have checked a cant/speed table that was pointed out to me by a resident of this good parish (though I cannot recall who-sorry) and a 10 chain with 5.5 inch cant gives a speed limit of 30MPH. However, it has been suggested to me that this table would only apply to stone ballasted track and that on a cinder/ash ballast, as I intended it to be, the cant and thus speed would be much lower. Would anyone care to tell me if that's the case? Thanks Derek EDIT: Perhaps the title should be "maximum cant on a slow speed line with cinder ballast" but I can't change it. |
