195mm curve directly.
The 195mm curve will connect with the 220mm curve by using the curved
turnouts 8568 and 8569. You will need one of each for each connection.
However, those curved turn outs are known to be a kind of a problem for
derailments if not set perfectly.
The combination will look like this:
outer curve in a 180° turn to the right:
8531 - 8568 - 8521 - 8521 - 8569 - 8531
inner curve in this turn_
8569 - 8521 - 8521 - 8521 - 8521 - 8568
If you want to connect those lines in a straight you have two options:
With a 25 mm gap as will result from using the 195mm and the 220mm curve
radii, you just need two right or two left turn outs. They will connect
the lines perfectly. When you want just to merge the two lines just
replace one turn out with a 8591 490mm curve.
If you have a 50mm gap between the lines, as you will in your example
then you need to set the two turn outs and fill in a 8507 112.8mm
straight to get the right distance.
