I think you're confusing CETC switch numbering system with high speed turnout numbering. In the CETC system (carried over to the ARINC system) switch numbers (more or less) indicate the track the switch starts on to the track the switch goes to going south to north and west to east. The No.23 switch therefor takes you from No.2 track to No.3 track. There are of course some exceptions to this system especially in larger plants.
Turnout numbers, based on the speed of the switch, are even numbers. Amtrak uses two types of turnouts on main tracks. They are a number 20 turnout which is good for 45MPH and a number 32 turnout which is good for 80MPH (I think, might be 90MPH now). The No.21 switch (2 to 1 track northbound) at "Grove" is a number 32 turnout which got you a "Cab speed" back when I had CETC 1 on afternoons. Out west on BNSF, where I now work, we use a number 24 turnout which is good for 50MPH.
