Track racing bike-build

In my experience you don't notice any difference in frame geometry. Over the last 2/3 years I've been riding a 50 year old steel road/path frame, and a modern Bianchi alu/carbon road bike on the track. I notice the differences in the contact points (track drops vs compact bars, saddle more over the bottom bracket etc), rather than the differences in the geometry.

That's a pretty wild claim. are you saying a touring frame or cross frame would ride like a track frame if you get contact points in same place?
