I'm planning a layout to use Peco OO/HO Finescale track, but I cannot find any information about the actual size, angle and radius of the points/switches and crossings (short of trying to measure photographs in website catalogues ). I haven't yet been able to get a copy of the Peco catalogue (and don't know if this info is in there anyway). Does anyone have these critical dimensions to hand, or know a website that has them, or some templates that could be printed out?
Small radius Y -- 24" radius, 24 degree angle, #2.25 frog Large radius Y -- 72" radius, 12 degree angle, #4.5 frog Small radius turnout -- 24" radius, 12 degree angle, #4.5 frog Medium radius turnout -- 36" radius, 12 degree angle, #4.5 frog Medium radius 3-way -- 24/36" radius, 12 degree angle, #4.5 frog Large radius turnout -- 60" radius, 12 degree angle, #4.5 frog Curved double radius t/o -- 60/30" radius, #4.5 frog Double slip -- #4.5 frog (matches long crossing) Long crossing -- 12 degree angle Short crossing -- 24 degree angle
As I understand it, Peco switches (at least in N-scale) have a diverging track that starts at the through track as a curved section and then transitions to a straight section. The dimensions that I would like to have for layout planning purposes are as follows (I would attach a diagram if I knew how). All are for the centerlines of the tracks. I'm interested in N-scale. - The distance, from each end of the through track, to where the diverging track starts. - The radius of the curved section of the diverging track. - The arc (i.e. angle covered) of the curved section. - The length of the straight section of the diverging track. Is there anybody out there that can get these, for any of the turnout sizes?
That's great Rob . Do you also know the overall length of each unit by any chance? The radius of the small switches surprises me - I thought they'd be about 12..18 inches. I'm doing an industrial setting in HO and was planning on a general 18" minimum radius for plain track. Am I being optimistic with that? (It won't be traversed by anything with more than 4 axles.)
