You can install high speed turnouts, but it's tight down in those old tunnels. They would need structural modifications. You cannot install "high spped" turnouts. All a high speed turnout is, is a higher frog number, with a longer length switch. Try building it on your model railroad. I did. I could not use No. 6 switches in my terminals because the terminal would then be longer than my table. I had to settle for No. 4 switches in the terminals. ERGO slower trains. NYP has an incredibly complex interlocking system with train running across many switch point between the platform and the tunnel. The train must be clear of the entire route before the interlocking plant will allow the realignment of switches for the next train. After all that *is* what an interlocking plant is, and why they call it thus. RORA
