MINIMUM TANGENT LENGTH BETWEEN REVERSE CURVES FOR SLOW SPEED
The objective of this report is to determine the minimum tangent length between reverse curves for slow speed operation. Within the report reverse curves from 6 deg through 16 deg which have no spiral and no superelevation were studied. The test train consists were operated at speeds equivalent to 3 inches of unbalanced superelevation. The Quasi-Static Lateral Train Stability Model program was used to determine the maximum L/V (lateral/Vertical forces) ratio and the maximum coupler lateral angles and this information was analysed to determine minimum tangent lengths.
