  • From LGB's web site (in terms of diameter, not radius)

    R1 = 1200 mm
    R2 = 1560 mm
    R3 = 2390 mm
    R5 = 4640 mm

    Tranlated into imperial:

    R1 - 47.2" diameter (2' radius)
    R2 - 61.4" dia (2' 6' rad)
    R3 - 94.1" dia (3' 11" rad)
    R5 - 182.7" dia (7' 7"rad)

  •  Was there ever an R4?

    Is there anything larger than R5?

    Thanks, Greg

  • Not with LGB. Other manufacturers, yes, but be forewarned that their "R" designations may or may not coincide with LGB's or others'. There doesn't seem to be any kind of standardization relative to that. (Which should shock and surprise absolutely no one.)

    Tranlated into even plainer English: Wink

    R1 - 47.2" diameter (2' radius) = 4' diameter
    R2 - 61.4" dia (2' 6' rad)          = 5' diameter
    R3 - 94.1" dia (3' 11" rad)       = 8' diameter
    R5 - 182.7" dia (7' 7"rad)        =15' diameter

    Yes they are rounded up and generalized, but it makes remembering them alot easier for dummies like me Dunce

      Have fun with your trains

  • I have made a table that has all this info for quick reference:

    May be helpful.

     Was there ever an R4?

    Yes (and No).  For a couple of years they had a switch that had an R4 turnout (around 3500mm) and a single piece of R4 curved track to "parallel the main line".  The R4 curve rail was NOT sold seperate from the switch. They discontinued the R4 about '82~'85? (could have been earlier)

  •  Where would LGB's 600mm curves be on this scale, are they even smaller than R1 or are they shorter sections of the 1200mm maybe?

    The current track sections I have are stamped R=600mm (like what I'm addressing above) and R=765mm. Although I may be answering my own question an old 91/92 LGB catalog identifies R1 as 60 cm, R2 as 76.5 cm and R3 as 117.5 cm.

    There have been a few times when radius has been used to describe curvature instead of diameter, especially during the early "Chinese" track. I believe you are looking at "Chinese LGB" which has a radius of 60 centimeters, which equals a diameter of 1200 millimeters. So in fact R1=R1 whether measured in radius or diameter whether measured in cm or mm. It's all the same size.
