I have started working on a new layout and found the XTrkCad software. Since it is free, it fits my budget just fine. I have not been able to find a file with Lionel traditional O-gauge track templates. It’s not that difficult to make a template if you have accurate dimensions and I can create the straight and curve pieces using basic math.
However, I need help creating the switches. The only switch I own right now are O-27 27" switches. If someone could be so kind as to provide the necessary measurements for the other switches, I can complete the template file. I’ll be happy to share once it is done.
I need information for the following traditional switches:
O-27 42" switch
Standard O 31" switch
Standard O 42" switch
Standard O 72" switch
The information I need is:
Turnout Length
Straight Length
Offset
Best guess at angle.
I should be able to calculate the angle using the standard curve dimensions and track length but a best guess would be useful.
Well Rob…everything is modular…it may be easier to build individual files of switches, and add them to the drawings, but I’m familiar with AutoCAD, and not your program.
Tubular is measured from center of outside rail. (Fastrack is measured from the center of the center rail)
31" radius: 8-sections per circle (45-degree divisions) same with the switches.
42" radius: 12-sections per circle (30-degree divisions).
54" radius: 16-sections per circle (22.5-degree divisions).
72" radius: 16-sections per circle (22.5-degree divisions) same with the switches.
The radius of O31 track is 14.142 inches. The length of an O27 straight section is (ideally) 8.839 inches. The straight section of an O27-profile O42 turnout is 13 21/32 inches (Lionel), 13 3/4 inchesc (old-style K-Line).
Diameter of tubular track is traditionally measured to the ends of the ties, but expressed as an integer-inch value close (but not necessarily the value closest) to the measured value.
