Also you need to take into account the era of the bike. My bike racing days were in the 70's. Early 70's racing bikes could probably be compared to 80's touring bikes. Large clearances and long wheelbase.

There was quite a shift around the mid 70's. Inspired by bikes like Colnago and Masi, American builders like Eisentraut and others started building tighter steeper angled frames. By the 80's the racing bike had shrunk by inches in wheelbase, and frame angles steepened accordingly.

A touring bike in the 70's was any bike you could throw some racks on. By the 80's we had fully outfitted touring bikes with racks attached to seatstay braze-ons.

The trend continued into the 80's and 90's with clearances getting really tight. Short reach brakes, vertical dropouts, and brazed-on everything were the norm.

Track bikes have one purpose, to go fast. Generally they have a higher bottom bracket for clearance on banked tracks. All the parts are beefier, including 1/8 inch chain/chainwheel/cog. Sprint bikes have steel bars and stems, pursuit bikes have alloy stem and bars.
