... the prototype they are really quite rare, despite being much loved by modellers. For example your design is difficult prototypically, because a) having two turnout stretcher bars exactly opposite each other causes problems with the rodding runs to the signal box, and b) on passenger lines your Y-turnout would need to be a wide-gauge style of catch points to protect the outer lines, and c) that makes the interlocking and signalling more complicated than needed. Much more likely on the prototype would be something like this: 2_220950_230000000.png The middle road continues to a short spur, which is a useful place to park an odd wagon or brake van. A tandem turnout then provides two conventional crossovers to the outer roads, and the turnouts are conveniently staggered. However, to return to your design, a symmetrical Y-turnout can be created using an irregular half-diamond template, with the peg on split deflection to create a switch front. I set the K-crossing angle to 1:24, which conveniently means you can use "A ...
