HEUMANN-LOTTER TYRE PROFILE

The Heumann-Lotter tyre profile was evolved with the idea of giving somewhat greater safety against derailment of lcomotives and rolling-stock. This profile was applied to all engine and tender wheels, and was felt to be of particular value with tender-first running with the tender nearly empty, a condition which gave the greatest risk of derailment. Before adoption as the standard profile by the German Federal Railway, 68 percent of all tyre-turning costs were due to needed flange re-profiling. Observations showed that the tyre mileage was 30 percent greater with the new profile than with the old.
