I and a couple other people were doing some stuff with some speed record data. Organizing the data, making some graphs, etc.
While doing the train speed records, though, we noticed an oddity. For some reason, there's an 80 year gap between when one record was set - 1854 - and when it was broken - 1934. The records go:
46 km/h (29 mph) 1829 48 km/h (30 mph) 1830 96.6 km/h (60 mph) 1848 125.6 km/h (78 mph) 1850 131.6 km/h (82 mph) 1854-06 166.6 km/h (104 mph) 1934-07-20 168.5 km/h (105 mph) 1935-03-05
This... doesn't really match the distribution for the rest of the records.
(speed is in meters per second)
So, being curious, I'm wondering: Why was there no increase in the speed record for 80 years? Was there no new technology being developed?
