Geometry of ROCO O Scale Turnouts

Curtiss,

I believe they are #6's.  As far as the distance between yard tracks is concerned, just add a short length of track between the switches to get the yard track spacing you want.  The newer Atlas switches are 5's and 7.5's.  

Hope this helps.

.......I have the insert from the package which seems to indicate that stringing them one after another might yield a track spacing of 95mm or ~3.5 plus inches, but when I do this it appears quite a bit less. Does anybody have any experience with this.......

The 95 mm spacing in the instruction sheet that I just looked for these turnouts does not show any ladder spacing, but does show that if you place two 'back to back' for a crossover, the distance between track centers is that 95 mm -- say, 3.75 inches However, this sheet is from a later production turnout, and is more abbreviated than earlier editions [ blue ink ] as I recall, which may have had more track layout sketches.

You might make sure the turnouts are assembled correctly if you purchased used;  I've purchased some over the years that have had RH frog sections with LH blade sections and vice versa, whether they were assembled -- even soldered -- or in boxes.

I'll look again, but although this is the 'standard' turnout on my layout, I don't think I have any "pure" ladder layouts to measure the resultant spacing -- sorry.

Best regards, SZ

I measured these yeasr ago and decided they were very close to #6.  It is my standard turnout, but again I don't use them for my yard ladder either.  

I set my track spacing at 4 inches.   On an earlier layout I used tighter spacing and ran into some problems with cars sideswiping if the track had any slight kinks.    Also with 4 inches, I can usually see car numbers which is a must for my switching paperwork.   I can also get my fingers in to rerail cars if necessary.

To get 4 inches I think you need to put a short section of straight track between each switch.  

My guess is they might come to less than 3.5 inches if you just string them together without a spacer piece.

I just checked my coal mine tracks.    There are 2 parallel tracks set up on 4 inch centers.    so not quite a yard but it shows the switch spacing.    I have an 8 1/4 inch long section of straight track separating the switches to get the 4 inch track spacing.

To get the spacing you want, try temporarily setting down two parallel tracks on the spacing you want and then locating the switches with diverging routes feed them.    Then measure the length of track required between the switches.

Thank you to those who have relied ; it was most helpful.  I have inserted a shirt section of straight track between turnouts and it works fine.
