Flange climb derailments: causes and prevention
WEBAug 7, 2023 — If the L/V exceeds Nadal's limit, there is risk of flange climb. Figure 2 shows that for a friction coefficient of 0.5 and a flange angle of 75 o, the Nadal limit is 1.13. For 63 o, the limit is 0.73. Wheels with low flange angles have a higher risk of flange climb. Figure 2 also shows that higher friction increases risk of flange climb.
Traction choices: overhead ac vs third rail dc
WEBJan 13, 2024 — A study performed for Dubai Metro found that a 1.5kV dc third rail traction system can also cost up to 13% less than a 750V dc third rail system. One cost saving measure is the ability to locate fewer substations at greater intervals which reduces maintenance costs. Typical substation spacing is roughly 1.5 - …
