When using these boosters, turns are HIGHLY unadvised, for the consequences could be dire, resulting in a crash. See [[H.S. Track]] for a detailed description of a crash. High Speed (H.S.) tracks/rails should only be used when spanning long straight distances. It takes more Booster Rails to get up to the top speed of 15 b/s (blocks per second). It takes about 10-15 H.S. Booster tracks to get up those speeds. Players are advised to use [[H.S. Transition Track]]s when "transitioning" to higher or lower speed sections of track.
Although the top speed is possible, it is not typical to reach those speeds. The average speed is about 11-13 b/s when using H.S. Booster Tracks. This is compared to the average speed of normal Powered Rail/track is about 8-10 b/s. Overall, H.S. Tracks/Rails make long-distance travel about 27% faster than typical Powered Rails.
