Popularity of 50cm track
From the text it seems like the 400mm system was mostly a prototype and the 600mm system the most widespread, but how common was the 500mm system? Was it just a stop-gap prototype or was it popular among those that didn't quite needed the capacity (and cost) of the 600mm system? — Preceding unsigned comment added by 84.48.66.184 (talk) 00:43, 3 October 2011 (UTC)
